This is a preview from our weekly newsletter. Each week I go ‘Beyond the News’ and handcraft a special edition that includes my thoughts on the biggest stories, why it matters, and how it could impact the future.

Tesla’s recent decision to scrap Radar in favor of a Camera-based approach for Autopilot and Full Self-Driving aligned with the company’s plans and statements over the past few Earnings Calls. For CEO Elon Musk, the goal has been to get away from radar and depend on camera systems for Tesla’s self-driving plan, but some owners are not convinced of the decision. Over the past few days, I have received several emails and Tweets about the decision, with some owners still not completely confident in the vision-based approach Tesla will take.

During the Q1 2021 Earnings Call just a few months back, Elon Musk made it clear Tesla would be switching to a Camera-based system for AP and FSD. Comparing the cameras to human eyes, Musk’s explanation made a lot of sense.

Musk said:

“When your vision works, it works better than the best human because it’s like having eight cameras, it’s like having eyes in the back of your head, beside your head, and has three eyes of different focal distances looking forward. This is — and processing it at a speed that is superhuman. There’s no question in my mind that with a pure vision solution, we can make a car that is dramatically safer than the average person.”

Tesla Model 3, Model Y builds in May 2021 will no longer equip radar

Now, the thing is, eyes, while great for seeing things that are in the clear, are highly effective, and it makes a lot of sense to try and use this sort of approach for self-driving because it is how humans have driven for years. But when humans are confronted with low visibility and severe weather on the road, the confidence goes down, and many drivers adjust by traveling at lower speeds. Some even pull over and wait for the weather to subside, a move that is rare for many but some simply do not like driving in bad weather.

This is where radar comes in handy because it can identify and locate objects and how far they are away from the vehicle in the event of low visibility on the road, which is something that the human eyes, or cameras, simply cannot do.

An email from an Australian reader seemed to narrow in this point even further. A man named Peter emailed me and stated that his Model 3 recently identified a truck that was ahead of him but concealed in an opaque, white mist several car links ahead of his vehicle. “I assumed that visualization was created as a result of radar. In those conditions, the message multiple cameras blocked or obstructed appeared and the autopilot screamed and handed over,” Peter said.

He then added, “On multiple other occasions I’ve noted on the visualization screen an unsighted vehicle obstructed by an SUV ahead of me.”

Without radar, the recognition of these vehicles would not be possible, so it brings some concerns to drivers who have utilized the radar system in vehicles to gain confidence in their surroundings.

Now, in a somewhat comical response to concerns, Musk posted a Reddit response from u/YukonBurger, which stated that they worked with radar a lot and were “very, very happy” with Tesla’s decision. It basically explained that trying to jive radar and cameras together is extremely difficult, and there are instances where using your eyes is just a better option because you can see how far you are away from things. Interestingly, the post does admit that “radar is really only good for reduced visibility situations where lane-keeping will probably also be degraded enough to not be worth it.” It concluded by stating that vision is still quick enough to avoid accidents or vehicles in front of the car in a short period of time, the real issue comes from cars behind you.

It seems that the real key to vision being a better approach comes down to the fact that, in clear conditions, it won’t have an issue identifying and removing itself from danger. Even in rainy conditions, where visibility isn’t necessarily bad, the vision approach is more advantageous than using radar.

The goal, ultimately, is to make the cars act as a human would, and humans don’t have radar. Instead, they compensate for reduced visibility with less dangerous driving. Slower speeds, more cautious navigation, and less frequent lane changes. Autopilot and FSD are already pretty timid and “shy” to begin with, it’s not like they’re out there driving like pissed-off teenagers.

I think that, while this move is somewhat worrisome for some drivers, the benefits outweigh the disadvantages. This has been a part of the plan for some time, and I think that now it is becoming a reality, some are starting to put the pieces together that there won’t be any radar so visibility limitations could end up being problematic. I wouldn’t worry, because I believe the cars will adjust just as humans do, they will simply be more cautious and more courteous on the roads in these settings.

A big thanks to our long-time supporters and new subscribers! Thank you.

Tesla CEO Elon Musk reveals new details about Robotaxi rollout

The first Tesla Robotaxi unit was spotted in Austin earlier today, and CEO Elon Musk is revealing some cool new details.

Tesla CEO Elon Musk has revealed new details about the company’s relatively imminent rollout of the Robotaxi platform as the suspected launch date of June 12 continues to near.

Earlier today, the first video showing the first driverless Tesla Robotaxi in Austin was shared on X, just a day after the City officially listed the company as an autonomous vehicle operator on its website. Tesla is listed as a company in the “Testing” phase.

The initial details of the Robotaxi are being revealed by Musk, who is carefully releasing small tidbits that seem to show the capabilities of the entire Tesla fleet, and not necessarily just the vehicles that will be involved in the initial rollout in Austin.

His first tidbit is one that many Tesla owners and fans will already know: many Teslas are capable of this driveless performance, but Full Self-Driving is not yet refined to the point where the software is quite ready to handle it. Current versions are robust, but not prepared for driverless navigation. The hardware, however, will enable Teslas to be Robotaxis, even if they’re already purchased by owners:

This is one of the biggest advantages Tesla has over other vehicle makers. Simply put, the Over-the-Air software updates that will roll out to FSD users will eventually make their cars into Robotaxis as well.

However, Musk shed some details on the version of FSD that is being run in these new Robotaxis that were spotted. Musk said that the version these Robotaxis are running is a new version, but will soon “merge to main branch.”

There is also an even newer version that has four times the parameters as this newer version that the test-stage Robotaxis are using, but Musk admits that this needs significant refinement before it is released to the public.

As of now, Tesla is simply teasing the actual launch date of the Robotaxi program, but Bloomberg reported earlier this month that it will occur on June 12.

A recent video posted on X has provided a first look at Tesla’s driverless robotaxi, which is expected to be deployed in Austin, Texas, this month. The vehicle was a new Tesla Model Y, which was followed by what appeared to be a manned chase car.

The short clip suggests that Tesla may be ramping up its preparations for its robotaxi rollout in Austin.

The First Robotaxi Sighting

It was evident from the short clip that the Tesla robotaxi was operating completely driverless. In the video, which was posted on X by @TerrapinTerpene, the driverless Tesla could be seen confidently making a turn. The vehicle looked and behaved like any other car on the road, save for the fact that there was no one in the driver’s seat.

Interestingly enough, the short video also provided a teaser on where Tesla will place its “robotaxi” logo on its self-driving cars. Based on the video, the robotaxis’ logo will be tastefully placed on the front doors, making the vehicles look sleek and clean.

Initial Rollout Imminent

Recent reports have suggested that Tesla is already starting the testing phase of its robotaxi service in Austin, Texas. Expectations are also high that Tesla’s initial fleet of self-driving vehicles will be utilizing a lot of teleoperation to ensure that they operate as safely as possible.

Updates to Austin’s official website recently have hinted at Tesla’s robotaxi launch. Just this Monday, Tesla was listed as an autonomous vehicle (AV) operator on Austin’s official Department of Motor Vehicles (DMV). Other AV operators listed on the site are Waymo and Zoox, among others.

Elon Musk, for his part, has noted that by the end of June, the public in Austin should be ready to take rides in Tesla robotaxis without an invitation. He also noted in late May that Tesla has been busy testing driverless cars on Austin’s city streets without any incidents.

The Tesla Model Y claimed its position as China’s best-selling SUV in May, with 24,770 units registered, according to insurance data from China EV DataTracker. 

The Model Y edged out competitors like the BYD Song Plus, which recorded 24,240 registrations, as well as Geely’s gasoline-powered Xingyue L, which took third place with 21,014 units registered, as noted in Car News China report.

Return To The Top

The Model Y’s return to the top of China’s SUV market follows a second-place finish in April, when it trailed the BYD Song Plus by just 684 units. Tesla China had 19,984 new Model Y registrations in April, while BYD had 20,668 registrations for the Song Plus.

For the first five months of 2025, Tesla sold 126,643 Model Ys in China, outpacing the Song Plus at 110,551 units and BYD’s Song Pro at 80,245 units. This is quite impressive as the new Tesla Model Y is still a premium vehicle that is significantly more expensive than a good number of its competitors.

Year-Over-Year Challenges

Despite its SUV crown, Tesla’s year-over-year performance in China is still seeing headwinds. May sales totaled 38,588 units, a 30% year-over-year decline. From January to May, Tesla delivered 201,926 vehicles in China, a 7.8% drop year-over-year. These drops, however, are notably affected by the company’s changeover to the new Model Y in the first quarter.

Exports from Tesla’s Shanghai Gigafactory also fell, with 90,949 vehicles being shipped from January to May 2025. This represents a decline of 33.4% year-over-year, though May exports rose 33% to 23,074 units.

China’s electric vehicle market, meanwhile, showed robust growth. Total NEV sales, which includes battery electric vehicles (BEVs) and plug-in hybrids (PHEVs), reached 1,021,000 units in May, up 28% year-over-year. BEV sales alone hit 607,000 units, a 22.4% increase.

Considering the fact that China’s BEV market is extremely competitive, the Tesla Model Y’s rise to the top of the country’s SUV rankings is extremely impressive.
