A new report shows that commercial vehicles are much higher polluters than passenger vehicles despite making up a much smaller portion of cars on U.S. roads. For this reason, the study’s authors say the U.S. should prioritize electrifying the commercial vehicles sector rather than just focusing on passenger vehicles.
PepsiCo- and KPMG-backed software logistics company Adiona Tech shared the Connected Thinking report on Tuesday, which suggests that last-mile combination trucks be electrified as soon as possible to help fight CO2 emissions. The company says that all urban deliveries of groceries, parcels, furniture and other goods should be performed by electric vehicles (EVs) by 2025.
“Commercial vehicles are a much bigger polluter than passenger cars and they are in desperate need of modernization,” Adiona writes in the report. “Large combination trucks are just 1 percent of vehicles on the road, but they produce 18 percent of vehicle emissions.”
The study compared Bureau of Transportation Statistics figures from 2019 to those of 2020 and 2021, looking at vehicle miles driven by passenger cars and trucks, along with their associated emissions. What it found was that emissions decreased significantly in 2020 and 2021, while truck miles and their associated emissions increased above 18 percent of road traffic emissions.

The report included several key findings, notably including that the average fuel consumption of combination trucks is roughly 20 times higher than that of a passenger vehicle. The report also says that switching just five of these combination trucks to green alternatives — such as hydrogen fuel cells or lithium batteries — would be comparable to the effects of buying EVs for 100 households.
While the average truck drives about 22,930 miles annually, the report notes that large combination trucks travel an average of 59,929 miles in the same period, and single-unit trucks only average 12,278 miles annually.
According to data sourced from the Bureau of Transportation, light-duty vehicles with a short wheelbase have an average fuel consumption of 481 gallons per year, compared to 640 gallons consumed on average by light-duty vehicles with long wheelbases, and 1,639 gallons on average by single-unit, two-axle trucks with six tires or more. However, the data also shows that combination trucks consume an average of 9,909 gallons annually.
In a press release, Adiona Tech CEO Richard Savoie highlights the need to prioritize larger freight in the fight against carbon emissions, beginning with those that travel the most.
“America needs to aggressively decarbonize the biggest emitters on the road, large freight and delivery vehicles,” Savoie said in the release. “The US automotive industry is at a crossroads, but it needs to act now to electrify every car on the road. Doing so requires connected thinking and collective action. We cannot transform the national fleet of nearly 300 million vehicles overnight, so we need to make decisions that make the biggest difference, for the lowest effort first.”
The passenger vehicle sector has adopted EVs much more quickly than others, as several automakers have now followed Tesla’s lead in building fully electric vehicles. While electrifying every car is still an important goal, Savoie explains, it shouldn’t be the only one.
“Frankly, the data shows that consumer adoption of EVs should not be America’s number one priority,” Savoie said. “Electrifying fleets is by far the most efficient way to reduce vehicle emissions. Every battery we put in a combination truck counts for 20 households buying an EV, and businesses often have fleets of hundreds of vehicles.”
“We must prioritize the electrification of these vehicles that are on the road most, travel the longest distances, and are the least fuel-efficient,” Savoie added.
Several companies have begun piloting or at least stated plans to purchase electric last-mile delivery vehicles, including FedEx, Amazon, Walmart and more.
Adiona Tech backer PepsiCo is one of the first companies to have begun electrifying its semi-truck fleet after purchasing an initial batch of Tesla Semis last year. A recent event showed some serious range results for the Semi, and PepsiCo detailed last month how the truck was helping it reach its own sustainability goals.

Tesla’s two recently-defunct flagship models, the Model S and Model X, are getting a big upgrade, according to the company’s Head of AI, Ashok Elluswamy.
Older Hardware 3 Model S and Model X vehicles have been the last major holdouts in Tesla’s Full Self-Driving v14 Lite rollout, and that wait now appears to be ending.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
At Tesla’s Cybercab launch, AI chief Ashok Elluswamy told Ryan McCaffrey that he thought the S and X build “was supposed to go out last week.” Evidently, Elluswamy expects the suite to be rolled out to those HW3 Model S and Model X very soon:
For my @Tesla friends – and specifically Model S & X owners with HW3 who are waiting on FSD v14 Lite – I spoke to @aelluswamy at the Cybercab launch, & when I asked for an ETA on v14 Lite for S/X owners, he said, “Oh, I thought it was supposed to go out last week.”
So: soon! 🙌

Those cars are not the current Model S and Model X, which already ship with Hardware 4. They are the pre-refresh flagships built around Tesla’s older Autopilot computer, often called HW3 or AI3.
Tesla stopped putting that computer in new vehicles years ago, which is why owners treat these S and X cars as a closed generation. Model 3 and Model Y vehicles on the same computer began receiving v14 Lite in late June 2026 and saw a wider North American expansion in July. South Korea followed as an early international market. The S and X versions of the same software never joined that wave.
v14 Lite is Tesla’s way of squeezing the current v14 driving stack onto hardware that cannot run the full AI 4 model. The company describes the process as distillation: behaviors learned on the newer computer, including reinforcement learning and offline models, are compressed so the older chip and cameras can use them as a guide.
Early descriptions put the distilled network at roughly 15 percent of the original size. The result is still supervised Level 2 driving. Tesla has been clear that HW3 cannot support unsupervised Full Self-Driving or robotaxi operation because of memory and bandwidth limits.
The feature list is what made the wait so frustrating for S and X owners, as plenty of new features are to be shipped with it.
Official notes for the first Lite build, firmware 2026.20.5.1, added parking, unparking, and reversing; arrival options for a parking lot, street, driveway, or curbside; speed profiles that stay available at all times; and start-from-park engagement. Tesla also claimed better handling of merges, forks, pedestrians, traffic lights, and cut-ins, plus fewer false slowdowns and smoother lane centering.
A mid-July follow-on build, 2026.20.6.10, added more of the Hardware 4 interface, including a standalone Self-Driving app and the ability to start a trip from Park without a brake-pedal confirmation.
Elluswamy called that version the one “likely going to wide release.”
That wide release already reached most other HW3 cars in the United States and Canada. International timing still depends on regional validation and regulatory approval. For S and X owners, the remaining work appears to be model-specific validation rather than a new software stack.
There is no official Tesla changelog or build number for those two models yet, only Elluswamy’s offhand timeline. Some HW3 drivers who already have Lite report large gains over v12.6; others have described new indecision or phantom braking. The next test will be whether the same software lands cleanly on the older flagships that have waited the longest.
Yesterday, we reported on Tesla Cybertruck getting some major adjustments from a manufacturing standpoint in an effort to make the all-electric pickup more cost-effective, more reliable, more serviceable, and more easily produced.
Tesla Cybertruck engineer reveals new changes in ‘constantly evolving’ pickup
One of those changes was the addition of a self-reinforcing polypropylene aero shield that sits underneath the truck. Previously, Tesla utilized aluminum for this, but the self-reinforcing polypropylene was more durable while also being cheaper and lighter.
Tesla has revealed another small change it made to the Cybertruck, and it has to do with the side repeater cameras.
Tesla does not wait for a new model year to improve its vehicles. On September 8, Cybertruck lead engineer Wes Morrill posted side-by-side photos of an updated side repeater camera housing now rolling off the line at Gigafactory Texas.
The triangular camera pod mounted on the front fender looks almost identical at first glance. A closer look reveals a revised contour that uses the air already flowing around the truck to keep the lens clearer in rain and road spray.
The side repeater camera was updated – the version on the left is the newer part which uses passive geometry to create airflow disturbance that better keep water off the lens while driving. No cost penalty, just pure vision improvement. pic.twitter.com/wAbXtcL1Jf

The side repeater cameras sit in an exposed position on the Cybertruck’s angular stainless-steel body.
In wet weather, they readily collect water droplets that can degrade the image Autopilot and Full Self-Driving use for lane changes and blind-spot monitoring. Early production trucks sometimes left owners wiping lenses by hand or accepting temporary restrictions on driver-assistance features.
Tesla has added washers to cameras on certain other models and on Cybercab prototypes, but those active systems add cost, complexity, and extra potential leak points.
The new housing solves the problem with passive geometry. Subtle changes in the surround create localized airflow disturbances as the vehicle moves. Those eddies physically push water droplets away from the optical surface. Morrill called the result “pure vision improvement” achieved at “no cost penalty.” Once the production mold is updated, every subsequent part costs the same as the original.
The advantages compound quickly. Clearer cameras in rain improve the reliability of driver-assistance features precisely when they are needed most. The design consumes no extra energy and introduces no new failure modes.
New Cybertrucks built after the tooling changeover receive the updated part automatically. Some owners of trucks delivered as late as June 2026 have already confirmed they received the revised housing. Retrofit questions have appeared in replies, and the cameras appear electrically compatible, though Tesla has not announced an official service program.
A few millimeters of reshaped housing will not make headlines the way a new battery pack does, but these changes are incremental and increase the Cybertruck’s effectiveness as a vehicle over time.
This improvement illustrates how Tesla continues to refine the Cybertruck after volume production began. Better wet-weather vision, zero added cost, and no extra hardware add up to a meaningful gain in everyday usability and safety.
Tesla is rolling out a new version of its Full Self-Driving suite to some owners that comes with the massive addition of a safety feature.
Tesla is rolling out Automatic Collision Evasion with the 2026.27.6 Software Update, which started rolling out to some vehicles last night. We received the update, along with Full Self-Driving v14.3.9, as well as v14.2 Lite, which has identical release notes as the previous version and seems to have some refinements and improvements in behavior and performance.

However, most of the attention has fallen on the Automatic Collision Evasion feature, which we covered in an article last week.
The function will activate Full Self-Driving to “try to keep your vehicle safe and then continue driving. It can engage in the following situations while you are driving manually:
- Scenario 1: A frontal collision is imminent and braking alone may not avoid it.
- Scenario 2: Your vehicle detects that you are not sufficiently attentive to the road (for example, reaching toward the back seat), or that Full Self-Driving (Supervised) may have been unintentionally disengaged.”
Essentially, FSD will take over when the vehicle determines you are not paying sufficient attention or are heading toward a potential collision. The addition of this feature is incredibly useful as distracted driving is a major issue in today’s world.
Along with the new safety feature is Tesla FSD v14.3.9, which has no additional release notes compared to the previous version, but in my first drives, my first impression is that operation is great, and parking is still sort of a pain point.
Just took a 15-mile round trip to the gym and back
Pretty on par with what FSD is nowadays – really good. Not enough time to see what’s good and what’s bad, but these first rides on any version feel shockingly good. They’re all pretty identical https://t.co/WN1qTg4bhE

Additionally, Tesla v14.2. Lite has arrived. A great review of that is available here:
— Zack (@BLKMDL3) September 9, 2026
The addition of an Automatic Collision Evasion feature is similar to that of other collision avoidance systems that are used by companies like Hyundai, Kia, and Genesis. These programs typically utilize radar and camera sensors to apply emergency brakes autonomously, though evasive steering in a manual driving mode is pioneered primarily by Tesla’s newest addition.
