Adoption of Tesla’s electric truck will be driven by regulation
It’s expected that the commercial trucking industry will begin to transform in the same way that the passenger automotive industry has. Fuel efficiency has become a new priority and electrification is now the go-to plan for achieving higher MPGs in heavy trucking. In much the same way that regulations pushed trucking towards lower pollution at the expense of efficiency in the 1970s, today’s trucking paradigm is seeing a push for more efficiency. At what expense?
A new report from Ravi Shanker at Morgan Stanley urges investors to consider electric and self-driving commercial trucking as an opportunity. Shanker says that regulations and economics will drive the industry towards electrification and autonomous technologies. The analyst says that this could happen as early as 2020, which is when new federal fuel economy regulations on heavy-duty vehicles begin to really gather steam. Although efficiency gains will be had with electrification and self-driving, Shanker makes it clear that this will be secondary to the demand created by regulatory pressure.
As usual, we look to California for a glimpse of what could be coming. California’s Sustainable Freight Action Plan calls for 100,000+ zero-emissions trucks to be on the road by 2030 in that state. There is debate as to whether this plan is realistic, but federal standards are also playing a large role. The U.S. Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (part of the federal Department of Transportation) have proposed emissions and fuel economy standards for heavy-duty vehicles. The first of these began with the 2014 model year.
For our purposes, the regulations affecting “combination tractors” (aka “tractor-trailer” or “18 wheeler”) models are pertinent. The 2018 standards are relatively loose and most in the industry believe they are achievable, but the EPA and NHTSA have proposed further standards to begin in 2021, with incremental increases thereafter through to 2027. The goals are largely aimed towards lower CO2 emissions with reductions of about four percent (depending on the vehicle type) being the goal. The reduction is not the issue with industry insiders, however, it’s the test cycle to be used, which some argue is less realistic and which disfavors other emissions that also have requirements to be met. This Phase 2 of the federal efficiency standards for heavy trucks is not yet finalized, but will very likely be the driving force behind national changes in trucks.
Equating these changes into standard numbers that the general public would understand is difficult. Heavy-duty trucks can range in fuel efficiency from 20 mpg or better down to 2-3 mpg. For most tractor-trailer combinations, MPG averages of 4-9 mpg are the norm, depending on load, tractor type, and area of operation. Most analysts calculate efficiency using fuel use in tons per mile with a relatively long distance (100-500 miles) being the average. Using this method, for example, in my time driving a tractor pulling a refrigerated trailer across all 48 states, my fuel economy average was about average for that sector of the industry at roughly 60 ton-miles per gallon. Today, these numbers are slightly higher, according to the latest U.S. Transportation Energy book. Using this method of calculation, a 2015 Toyota Prius is about a third as efficient at moving freight as was my truck.
This doesn’t mean there isn’t room for improvement, of course. There are more companies than Tesla working towards deleting the smoke stacks from big trucks.
In Europe, Volvo trucks is working hard towards a zero-emissions (at the tailpipe anyway) trucking solution with several approaches being tested. An overhead tram-like charging system has been deployed for a short stretch of highway in Sweden, aiming to improve plug-in trucks’ range in EV mode. Short-haul battery electrics and two different versions of autonomous (or semi-autonomous) systems are also being tested.
Here in the States, Volvo’s Mack Trucks is working on a handful of electrification options for heavy-duty drivetrains. So is Daimler (Freightliner, Western Star in the U.S.). Startups like Nikola also have eyes on this electric trucking future. Other startups have hoped to get into the mix as well, but the failure rate is high with companies like Smith Electric, Vision Industries, and Boulder Electric having designed and marketed innovative commercial truck options that ultimately never caught on.
Meanwhile, the largest maker of electric heavy vehicles is Chinese maker BYD, who branched out from making gadget batteries into building electric buses, trucks, and more. They are currently filling contracts internationally for buses and trucks in places as disparate at California, Malaysia, and Europe. BYD builds battery-electric, hydrogen fuel cell electric, plug-in hybrid, and hybrid drivetrains and machines for several commercial market sectors.
So we can guarantee that changes to the trucking industry are coming, but no one can say how fast or how much change that will be. Current federal regulations will drive the industry forward until 2018 and it’s likely that new standards will be in place to keep carrying change forward after that. California’s ambitious plans for adopting electric trucks will be largely regulation and incentive driven, but that has down sides as well. Many of the startups we’ve seen who’ve created electrified big rigs or delivery trucks ultimately failed when the incentives began to dry up.
For Tesla, this could mean that the financial case for the Tesla Semi will need to be more economics-based and less dependent on single market, incentives-based plans. This means that Elon and Co should be looking beyond California and it’s 100,000 vehicle plans into a broader market. We’ll discuss the potential economic case for a Tesla Semi in a future editorial.
Tesla has reached a notable benchmark in its autonomous driving program after its Robotaxi fleet surpassed one million miles of unsupervised operation. The company made the announcement during its Cybercab event in Austin on September 3.
Tesla Vice President of AI Ashok Elluswamy told attendees he was happy to report the fleet had achieved one million miles of unsupervised Robotaxi operation as a testament to safety.
The new total marked a sharp increase from the 380,000 unsupervised miles Tesla disclosed during its second-quarter 2026 earnings update in late July.
In roughly six weeks, the company added about 620,000 miles. That acceleration followed Tesla’s decision to remove in-vehicle safety monitors from most of its operations outside the San Francisco Bay Area.

Tesla first launched Robotaxi service in Austin in June 2025 with safety drivers present. It later began fully unsupervised rides and expanded into Dallas, Houston, Miami, Orlando, and Tampa. The San Francisco Bay Area remains the exception, where a safety monitor still rides in the vehicle under California permitting rules.
The company has not released a city-by-city breakdown of the one million unsupervised miles.
The milestone arrived as Tesla began offering public Cybercab rides in Austin. The purpose-built vehicle has no steering wheel or pedals and is designed only for autonomous ride-hailing. Production versions joined the existing fleet of modified Tesla vehicles already operating in the service.
Tesla’s unsupervised mileage is growing at a double-digit weekly rate according to earlier company comments, yet its fleet size remains modest compared with established competitors. Waymo has accumulated more than 200 million fully autonomous rider-only miles. Tesla has described its own unsupervised operations as having recorded zero notable incidents in the period leading up to the July update.
The one-million-mile figure reflects Tesla’s shift from supervised testing to broader driverless service in multiple states. It also highlights the company’s strategy of using both existing Model Y vehicles and the new Cybercab to scale its network.

Whether the rapid recent growth continues will depend on further city expansions, regulatory approvals, and the performance of the purpose-built Cybercab in everyday paid rides. Tesla has not specified how many of the latest miles involved the new vehicle versus the rest of the fleet.
The announcement underscores Tesla’s progress toward a larger robotaxi network while illustrating the remaining gap in total autonomous experience relative to longer-operating rivals.
Tesla AI lead Ashok Elluswamy said this week that 24-hour Robotaxi service is close. Replying on X to a rider who wanted Cybercab trips all night, he wrote that the capability would arrive “next month or so” once “the next tech to merge on the v15 plan” is ready.
The comment landed on September 4, one day after Tesla opened public Cybercab rides in Austin. It is the clearest near-term timeline yet for overnight unsupervised operation. Tesla’s paid Robotaxi network currently runs from 6 a.m. to 10 p.m. seven days a week across Austin, Dallas, Houston, Miami, Orlando, and Tampa.
next month or so. the next tech to merge on the v15 plan will enable it.

That 16-hour window is shorter than the 6 a.m. to 2 a.m. schedule the company used for much of the prior year.
Elluswamy did not name the specific feature or say whether the change would apply first to purpose-built Cybercabs, the existing Model Y fleet, or both. He also offered no city-by-city rollout list. The link to Full Self-Driving v15 is nevertheless significant.
Tesla has described v15 as a step-change architecture with seven parallel improvement tracks and roughly ten times more parameters than earlier builds. Early versions of that software already operate on the Robotaxi fleet and contain about 40 percent of the planned gains.
By July 2026, the unsupervised fleet had logged more than 380,000 miles across six cities in two states with what the company called an impeccable safety record and no notable incidents caused by the vehicles themselves. Tesla has repeatedly argued that camera-based end-to-end neural networks, rather than extra sensors, are the core of the solution.
Overnight service would test that claim in lower-light conditions and would also raise vehicle utilization, a key variable for Robotaxi unit economics. The company has already begun using public Superchargers at night and is building dedicated Robotaxi charging sites.
Riders have asked why software must change if the cars already drive in the dark. The practical answer appears to be reliability and scale: Tesla has held back mass expansion until more of the v15 stack is merged, citing the need for higher confidence before putting thousands of unoccupied vehicles on streets around the clock.
If the next module arrives on the timetable Elluswamy sketched, 24-hour service could begin in October 2026 in at least some markets.
That would mark a shift from a daytime-bounded pilot to a service that can run whenever demand exists, including the late-night hours that have so far remained out of reach.
Tesla is beginning to roll out Full Self-Driving Supervised v14.3.9 with a new active safety layer that can take control even when the driver is operating the car manually.
Tesla AI said the software can activate FSD on the driver’s behalf when an imminent collision is detected and Automatic Emergency Braking may not be enough. It may also engage if the system detects heavy distraction or an accidental FSD disengagement.
FSD Supervised v14.3.9 starting to roll out shortly
This release includes a new active safety feature set: FSD Supervised can now activate on your behalf when an imminent collision is detected and Automatic Emergency Braking (AEB) may not be enough.
It may also engage if we…

The capability is essentially Automatic Collision Evasion. However, unlike conventional AEB, which mainly applies the brakes in a straight line, this feature can use steering, braking, and acceleration together if the car calculates that stopping alone will not prevent impact and a safer path exists. The system may change lanes or move toward a shoulder when conditions allow, then continue driving after the immediate threat is handled rather than simply coming to a stop.
The intervention is meant as a last-resort safety net, not a replacement for attentive driving.
Tesla Full Self-Driving v14.3.7 early review: FSD saved me from an accident
Tesla’s own description still frames FSD as supervised assistance. Secondary reports on internal release notes say the feature can fire while the car is being driven manually if cabin-camera monitoring suggests the driver is not sufficiently attentive, such as reaching toward the back seat, or if FSD appears to have been turned off unintentionally.
After the emergency maneuver, the car is expected to alert the driver and request a return to manual control.
The safety case is straightforward. Many collisions happen in the last second because a driver is looking away, fumbles a control, or faces an obstacle that braking cannot fully solve. A system that can both recognize that AEB is insufficient and execute a coordinated evasive path can reduce those remaining high-severity events.
Re-engaging after accidental disengagement also addresses a practical failure mode: a small steering nudge that drops FSD at the worst moment. The advantage is a background safety net that uses the same vision stack already running in v14, instead of leaving the car solely to emergency braking once the driver is no longer in command.
The feature still depends on FSD being enabled and, according to reports, an active FSD purchase or subscription. It does not make the vehicle unsupervised. Drivers remain responsible, and Tesla has not published how often the system is expected to intervene or how it will handle false positives.
If the rollout is conservative and the false-alarm rate stays low, the update is a meaningful step: FSD is no longer only a feature the driver turns on. In the rare moments when disaster is already forming, it can step in.
