Automakers come to accept that the EV revolution has begun
The last several months have been busy in the electric vehicle revolution. Governments have been announcing their phase out plans for petrol vehicles and automakers have committed billions of dollars to electrification programs. At this point automakers are practically falling over each other racing to get out their announcements. How many electric vehicles they’re developing, how much they’re investing, are they going fully electrified, and when. Suddenly no one wants to be perceived as falling behind in this revolution. And why should they? Nokia and Blackberry can attest to what happens if you do.
In the past, established automakers have been very cautious with electrification, with many simply watching to see how the situation developed. Generally, their investments could be best described as vague or immaterial to their core business of making cars. That’s clearly changed – take a look at the timeline of announcements below.
Taken as a whole these announcements are really quite striking. Most recently it was GM and Ford that released their competing declarations of electrification. GM with twenty new fully electric vehicles by 2023 and Ford quickly following up to say they had a new dedicated team for fully electric vehicles, while reiterating their previously committed $4.5 billion in investments for 13 new electrified vehicle options. Ford followed up the next day to say they were also diverting one third of their investments from combustion vehicle development.
The month prior was filled with even more announcements, including tweets between Elon Musk and Mercedes about the size of the latter’s investments. Volkswagen, BMW, Mercedes, Jaguar, Honda, BYD, and Dyson all made significant announcements about their EV programs that month, but it was Volvo’s “fully electrified” announcement that first caught the media’s attention back in July. It was a clever, if somewhat misleading PR move, but it did set important targets for their company and the competition. The fact that Tesla started producing their mass market Model 3 was almost lost amongst all this news. That’s an exaggeration of course, but only a year ago many believed their plans were impossible.
Government announcements have been another important part of the narrative, with targets that provide direction and impetus to the industry. Based on some of the lobbying it hasn’t been entirely welcome, but that’s to be expected. Anytime an entire country is talking about completely phasing out your current business model, it’s going give an industry pause. In this case there were multiple, with China, the UK, France, India, and several others weighing in with their plans to phase out combustion vehicles.
Looking at these announcements together suggests that a new phase in the electric vehicle revolution has begun. The fundamentals behind this shift are what I will argue here. My proposition is that the combined macro-economic drivers of regulation, competition, and market growth are pushing EVs to the mainstream. Be forewarned, it’s a long post, but analyzing any of these factors in isolation loses the bigger picture. Electric vehicles are coming, of that there can be no doubt.
Regulation, competition, and market growth.
You’ll notice the analysis below centers around plug-in electric vehicles (PEVs). Today a little more than 60% of new EV sales are pure battery electric vehicles (BEVs) and the rest are plug-in hybrid electric vehicles (PHEVs). PHEV’s are a transitionary technology, which currently offer some benefits that will disappear as battery costs continue to fall and range continues to increase. Note that the analysis doesn’t include hybrids without plugs, they’re old news. Also note that in talking about vehicles and vehicle sales, these are always in reference to passenger vehicles (i.e. no freight trucks). Annual passenger vehicles sales data was taken from the International Organization of Motor Vehicle Manufacturers and electric sales information is from the International Energy Agency.
Regulation:
The 2015 Paris climate agreement requires country specific greenhouse gas reductions by 2030 or sooner. As part of the agreement countries must also submit annual reports on their progress. Transport is a key part of each country’s emissions and it’s one that has a solution at hand, hence the plans to phase out combustion vehicles. France and UK announced for bans by 2040, Scotland by 2032, Netherlands 2025, Norway 2025, and India and China in development. There’s some subtlety to each. Norway for example is leaning towards economic levers to achieve their goals in lieu of outright restrictions, while India has said they expect all vehicles to be electric by 2030 without regulation being necessary, though their official policy is expected later this year.
Personally I tend to agree. I expect we will all be buying electric vehicles long before 2040 largely due to economics, especially with carbon pricing. That said, all of the government announcements are important. They provide both the public and automakers a framework in which to operate, while the more aggressive targets are actually moving the industry forward.
California and nine east coast states have long mandated a portion of sales be zero emission vehicles (ZEVs), administered through a credit system. The system gives partial credit to plug-in electric vehicles (PEVs) and more credits to long range zero emission vehicles (ZEVs). It’s basically the reason automakers have produced ZEVs in the USA. In quite possibly the biggest announcement of the year China is now doing something similar. They’ve mandated a ‘new energy vehicle’ credit requirement of 10% of sales in 2019 and 12% in 2020. Since one EV can be responsible for multiple credits it means that less than 12% of all vehicles sold will be required to be zero emission vehicles. For example, if the requirement was met with vehicles like the BMW i3, it would mean 4.6% of all vehicle sales in China would be ZEV in 2020, about 1.4 million that year. For reference there are about 2.5 million PEVs on the planet right now.
China is also looking at establishing a date for complete phase out of petrol vehicles, which has caught California’s attention. California is not eager to lose their leadership position in electric vehicles and is now looking to increase their own targets and establish their own timeline for complete phase out. I believe the quote from their governor was “Why haven’t we done something already?”. It seems that an EV target race has begun and that means mandated growth for the EV market.

Market Growth:
This one has always been a bit of ‘chicken or the egg’ scenario. Historically demand for electric vehicles was low, which automakers referenced as the reason for their limited offerings. Others argued that there could be no demand when so few options were available, especially when those that did exist had such weird aesthetics (which was an effective way to prevent scavenging from more profitable combustion sales). Tesla flipped this around with their preorders of the Model 3 and showed everyone the latent demand to the tune of nearly 400,000 preorders. Other automakers took notice. BMW even started having widespread video presentations depicting the threat of Tesla to motivate their employees.
If you’ve only heard the rhetoric of how electric vehicles constitute a small fraction of the world’s annual sales, you might have missed something important. Exponential growth. Since 2012 growth of plug-in electric vehicles has been over 40% every year. Cumulatively that means 10x more PEVs will be sold in 2017 than 2012, as shown in the graph below.

Historical data from the IEA, 2017 estimate from EVvolumes.com
Don’t get me wrong, the existing market share is almost laughably low at 1.1% worldwide (2016 data from the IEA), but over the last three years sales have grown at an average 54.6% compound annual growth rate (CAGR).
To illustrate the effect of exponential growth consider the following example about bacteria in a jar. If the number of bacteria doubles every minute and after 1 hour the jar is full of bacteria, that means at 59 minutes the jar is half-full, at 58 minutes ¼ full, at 57 minutes 1/8 full, etc. At 54 minutes that jar is only 1.6% full and everyone is thinking that bacterial will never fill the jar. It’s simplistic and exaggerated but that’s where we are today, at 54 minutes.
The example shows the power of exponential growth but also the challenge in forecasting it. Over the long term, small changes in annual growth rates can have big impacts. Solar power projections were notoriously underestimated and each year forecasts had to be revised upwards. That’s not to disparage the forecasters, it’s incredibly difficult to do what they do and certainly some caution in forecasting is warranted. But it is worth considering that electric vehicles may be in a similar situation. For example, Bloomberg New Energy Finance (BNEF) posted an EV outlook report in 2016, estimating that annual sales in 2040 would be 35% of all vehicles sold and the total PEV fleet would be 410 million. This year they revised those projections up, to 54% and 600 million. That’s 200 million more EVs, on a starting estimate of 410 million, after one year of new data. Will the next years’ forecasts also be revised upwards?
Shorter timeframes are usually more accurate, BNEF’s numbers indicate they expect approximately 2.5 million PEVs to be sold in 2020. That seems reasonable, but it would mean that PEV sales growth slows to 35% annually for the next few years. With more models coming that have better features and lower costs, and with governments now pushing the market with more aggressive targets, it seems unlikely growth will slow. So as an experiment what happens if the 54.6% growth rate over the last three years continues, to 2020 and 2025?
The impact would be impressive. The graph indicates that over 4 million PEVs would be sold in 2020, for 5% of total vehicle sales. That jumps to 37 million PEVs sold in 2025, nearly 40% of the total vehicle sales predicted. Contrast that with BNEF numbers, of 3% of sales in 2020 and 8% in 2025. Personally I think 8% is a low estimate for 2025, it works out to a compound annual growth rate of approximately 25%. Interestingly UBS increased their 2025 PEV estimate upwards by 50% this year (from 2016) to 14% of total sales – showing that short-term projections can be just as uncertain.
Perhaps 54.6% isn’t feasible, although Tesla has nearly managed it with a 47% growth rate since 2013. They did this while building up their staff, infrastructure, technology, and procedures virtually from scratch all at the same time. It’s also worth considering the history of smartphones. Globally smartphone sales grew at a rate of 46.4% year over year for ten years from 2004 to 2014, growing from sales of 27 million a year to over a billion. It was even more dramatic in China, where smartphone users accounted for about 5% of mobile subscribers in 2010 but were 70% by 2015 (Statista). That’s in just 5 years.

Data from www.gartner.com
Granted smartphones are not cars. The average smartphone costs orders or magnitude less and is traded in every two years, while the average car is traded in every 6.5 years (in the USA). A smartphone apparently has an average total lifespan of 4.7 years and a car can last to ~200,000 miles, approximately 15 years of average driving.
But electric cars do offer something cell phones never have. A lower cost. Cell phones provide a wealth of new functionality in our lives, but generally at a premium. Today, electric cars already cost less to operate than combustion vehicles, by 2018 they are expected to reach cost parity on total cost of ownership (UBS report), and by 2025 Bloomberg expects them to cost less upfront than combustion vehicles. That’s battery only electric vehicles (BEVs). Perhaps the changeover is longer than it was for cellphones, but once BEVs have an upfront cost less than petrol, why would anyone buy anything else?
Competition:
More and more manufacturers are entering the electric vehicle field with legitimate programs and their EVs are getting excellent reviews. At the end of 2016 the Chevy Bolt came out and won the North American and Motor Trend car of the year awards. Be prepared to see future EVs dominate the awards. VW already has a new e-Golf, Nissan a new Leaf, BMW an updated i3, Hyundai released their Ionic, and Audi, Porsche, and Jaguar are all coming out with pure EV models in 2018. Then there are the massive “electrification” shifts from the likes of Mercedes, BWM, Volvo, Austin Martin, VW, Ford, GM, and others. All now committing to reshaping their companies and the industry by moving to electric vehicles. There’s also that company Tesla which started making their game changing Model 3. Suddenly there’s a lot of competition and if your company isn’t one of those competing…. what are you doing? Those automakers on the sidelines are starting to look obsolete and it’s a short road from obsolete to ‘out of business’.
With automakers and governments committing to electrification of vehicles, we are going to see a significant ramp up in the electric vehicle market. More plug-in options are coming out, billions are being invested, and governments are seriously planning the end of combustion vehicles. It really is a paradigm shift. In large part we have Tesla to thank. If they hadn’t shown the world what was possible, who knows when this would have happened. Certainly the future would be a bit darker.

Tesla Optimus V3 hand and arm details revealed in new patents
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
Tesla is planning to soon reveal its latest and greatest version of the Optimus humanoid robot, and a series of new patents for the hands and arms, with the former being, admittedly, one of the most challenging parts of developing the project.
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
The designs relocate heavy actuators to the forearm, route cables through a sophisticated wrist design, and employ innovative joint assemblies to achieve human-like dexterity while enabling lightweight construction and high-volume manufacturing.
Core Tendon-Driven Hand Architecture
The primary patent, which is titled “Mechanically Actuated Robotic Hand,” details a cable/tendon-driven system.
Actuators are positioned in the forearm rather than the hand. Each finger features four degrees of freedom (DoF), while the wrist adds two more.
Tesla’s Optimus V3 robot hand looks to have been revealed in a new international patent published today.
The patent describes a tendon/cable-driven hand:
• Actuators in the forearm
• Each finger has 4 degrees of freedom
• The wrist has 2 degrees of freedom
• Tendon-driven… pic.twitter.com/eE8xLEYSrx— Sawyer Merritt (@SawyerMerritt) April 16, 2026
Three thin, flexible control cables (tendons) per finger extend from the forearm actuators, pass through the wrist, and connect to the finger segments. Integrated channels within the finger phalanges guide these cables selectively—routing behind some joints and forward of others—to enable independent bending without unintended motion.
Patent diagrams illustrate thick cable bundles emerging from the wrist into the palm and fingers, with labeled pivots and routing guides. This setup closely mirrors human forearm-muscle and tendon anatomy, where most hand control originates proximally.
Advanced Wrist Routing Innovation
One of the standout features is the wrist’s cable transition mechanism. Cables shift from a lateral stack on the forearm side to a vertical stack on the hand side through a specialized transition zone.
Boom! @Tesla_Optimus 의 3세대 구조로 추정되는, 로봇 팔 및 관절에 대한 특허가 공개되었습니다.
아티클 작업에 들어가겠습니다.
1년 넘게 기다려 온, 정말 귀한 특허인데, 조회수 100만대로 터져줬으면 좋겠네요. 😉@herbertong @SawyerMerritt@GoingBallistic5 @TheHumanoidHub pic.twitter.com/CCEiIlMFSX

This geometry significantly reduces cable stretch, torque, friction, and crosstalk during combined yaw and pitch wrist movements — common failure points in simpler tendon systems that cause imprecise or jerky motion.
By minimizing these issues, the design supports smoother, more reliable multi-axis wrist operation, essential for complex real-world tasks.
Companion Patents on Appendage and Joint Design
Two supporting patents provide additional depth. “Robotic Appendage” covers the overall forearm-to-palm-to-finger assembly, with a palm body movably coupled to the forearm and finger phalanges linked by tensile cables returning to forearm actuators. Tensioning these cables repositions the phalanges precisely.
“Joint Assembly for Robotic Appendage” describes curved contact surfaces on mating structures paired with a composite flexible member. This allows smooth pivoting while maintaining consistent tension, enhancing durability, and simplifying assembly for mass production.
Executive Insights on Hand Development Challenges
Tesla executives have consistently described the hand as the most difficult component of Optimus.
Elon Musk has called it “the majority of the engineering difficulty of the entire robot,” emphasizing that human hands possess roughly 27–28 DoF with an intricate tendon network powered largely by forearm muscles. He has likened the challenge to something “harder than Cybertruck or Model X… somewhere between Model X and Starship.”
In mid-2025, Musk acknowledged that Tesla was “struggling” to finalize the hand and forearm design. By early 2026, he stated that the company had overcome the “hardest” problems, including human-level manual dexterity, real-world AI integration, and volume production scalability.
He estimated the electromechanical hand represents about 60 percent of the overall Optimus challenge, compounded by the lack of an existing supply chain for such precision components.
These patents directly tackle the acknowledged pain points: relocating actuators reduces hand mass and inertia for better speed and efficiency; advanced wrist routing and joint geometry address friction and crosstalk; and simplified, stackable parts visible in the diagrams indicate readiness for high-volume manufacturing.
Implications for Optimus Production and Leadership
Collectively, the patents portray the Optimus v3 hand not as a mere prototype, but as a production-oriented system engineered from first principles.
The 22-DoF architecture, forearm-driven tendons, and crosstalk-minimizing wrist deliver a clear competitive edge in dexterity. They align with Musk’s view that high-volume manufacturing is one of the three critical elements missing from most other humanoid projects.
For Optimus to become the most capable humanoid robot, its hand needed to replicate the useful and applicable design of the human counterpart.
These filings demonstrate that Tesla has transformed years of engineering challenges into patented, elegant solutions — positioning the company strongly in the race toward general-purpose robotics.

Tesla intertwines FSD with in-house Insurance for attractive incentive
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla intertwined its Full Self-Driving (Supervised) suite with its in-house Insurance initiative in an effort to offer an attractive incentive to drivers.
Tesla announced that its new Safety Score 3.0 will automatically have a perfect score of 100 with every mile driven with Full Self-Driving (Supervised) enabled.
The change is designed to boost customers’ average safety scores and deliver noticeably lower monthly premiums.
The move marks the clearest link yet between Tesla’s autonomous driving technology and its proprietary insurance product. Tesla Insurance already relies on real-time vehicle data—such as acceleration, braking, following distance, and speed—to calculate a Safety Score between 0 and 100. Higher scores have long translated into cheaper rates.
Under the previous system, however, even brief manual interventions could drag down the average, frustrating owners who rely heavily on FSD. Version 3.0 eliminates that penalty for supervised autonomous miles, effectively treating FSD-driven segments as the safest possible driving behavior.
The incentive is immediate and financial. Drivers who keep FSD engaged for the majority of their trips will see their overall score rise, potentially shaving hundreds of dollars off annual premiums.
Tesla framed the update as a direct response to customer feedback, many of whom had complained that the old scoring model punished the very behavior it was meant to encourage.
For now, the program applies only to new policies in six states: Indiana, Tennessee, Texas, Arizona, Virginia, and Illinois.
Existing policyholders are not yet included, a point that drew swift questions from the Tesla community. Many owners in other states, including California and Georgia, expressed hope that the benefit would expand nationwide soon.
The announcement arrives as Tesla continues to roll out FSD Supervised updates and push for regulatory approval of more advanced autonomy. By tying insurance savings directly to FSD usage, the company is putting its own actuarial weight behind the technology’s safety claims.
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla has not disclosed exact premium reductions or the full rollout timeline beyond the six launch states.
Still, the message is clear: the more drivers trust FSD Supervised, the more Tesla Insurance will reward them. In an era when legacy insurers remain cautious about autonomous tech, Tesla is betting that its own data will prove the safest miles are the ones driven hands-free.

Tesla finalizes AI5 chip design, Elon Musk makes bold claim on capability
The Tesla CEO’s words mark a strategic shift. Tesla has long emphasized software-hardware co-design, squeezing maximum performance from every transistor. Musk previously described AI5 as optimized for edge inference in both Robotaxi and Optimus.
Tesla has finalized its chip design for AI5, as Elon Musk confirmed today that the new chip has reached the tape-out stage, the final step before mass production.
But in a brief reply on X, Musk clarified Tesla’s AI hardware roadmap, essentially confirming that the new chip will not be utilized for being “enough to achieve much better than human safety for FSD.”
He said that AI4 is enough to do that.
Instead, the AI5 chip will be focused on Tesla’s big-time projects for the future: Optimus and supercomputer clusters.
Musk thanked TSMC and Samsung for production support, noting that AI5 could become “one of the most produced AI chips ever.” Yet, the key pivot came in his direct answer: vehicles no longer need the bleeding-edge silicon.
And thank you to @TaiwanSemi_TSC and @Samsung for your support in bringing this chip to production! It will be one of most produced AI chips ever.
— Elon Musk (@elonmusk) April 15, 2026
Existing AI4 hardware, which is already deployed in hundreds of thousands of HW4-equipped Teslas, delivers safety metrics superior to human drivers for Full Self-Driving. AI5 will instead accelerate Optimus robot development and massive Dojo-style training clusters.
The Tesla CEO’s words mark a strategic shift. Tesla has long emphasized software-hardware co-design, squeezing maximum performance from every transistor. Musk previously described AI5 as optimized for edge inference in both Robotaxi and Optimus.
Now, with AI4 proving sufficient, the company avoids costly retrofits across its fleet while redirecting next-generation compute toward higher-value applications: dexterous robots and exponential training scale.
But is it reasonable to assume AI4 enables unsupervised self-driving? Yes, but with important caveats.
On the hardware side, the claim is credible. Tesla’s FSD stack runs end-to-end neural networks trained on billions of miles of real-world data. Internal safety data reportedly shows AI4-equipped vehicles already outperforming average human drivers by a significant margin in controlled metrics (collision avoidance, reaction time, edge-case handling).
Dual-redundant AI4 chips provide ample headroom for the driving task, leaving bandwidth for future model improvements without new silicon. Musk’s assertion aligns with Tesla’s pattern of over-provisioning compute early, then optimizing ruthlessly, exactly as HW3 once sufficed before HW4 scaled further.
Optimus and our supercomputer clusters.
AI4 is enough to achieve much better than human safety for FSD.
— Elon Musk (@elonmusk) April 15, 2026
Unsupervised autonomy, meaning Level 4 or higher, is not solely a compute problem. Regulatory approval remains the primary gate.
Even if AI4 achieves “much better than human” safety statistically, agencies like the NHTSA demand exhaustive validation, liability frameworks, and public trust.
Tesla’s supervised FSD has shown rapid gains in recent versions, yet real-world edge cases, like construction zones, emergency vehicles, and adverse weather, still require driver intervention in many jurisdictions. Competitors like Waymo operate limited unsupervised fleets, but only in geofenced areas with extensive mapping. Tesla’s vision-only, fleet-scale approach is more ambitious—and harder to certify globally.
In short, Musk’s post is both pragmatic and bullish. AI4 is likely capable of unsupervised FSD from a technical standpoint. Whether regulators and consumers agree, and how quickly, will determine if Tesla’s bet pays off.
The company’s capital-efficient path keeps existing cars relevant while pouring future compute into robots. If the safety data holds, unsupervised autonomy could arrive sooner than many expect.
