Tesla case against Xpeng Motors over alleged Autopilot code theft faces roadblock

Tesla’s case against Chinese EV maker Xpeng Motors over the alleged theft of its Autopilot source code recently reached an unfortunate roadblock. In a recent update, a federal judge rejected a request from Tesla that would allow the company to access grand jury materials related to a former Apple engineer, who reportedly stole trade secrets before joining the Chinese EV maker. 

Back in mid-January, Tesla subpoenaed XMotors, the US business unit of the China based Xpeng Motors. This was seen as a bid to gather evidence in its civil lawsuit against Cao Guangzhi, who previously worked on Tesla’s Autopilot team as an engineer. Guangzhi is accused of misusing Tesla’s intellectual property for the benefit of Xpeng, his new employer. 

Tesla requested access to several materials, including the entire repository of Xpeng’s XPilot source code, referring to the Chinese EV maker’s own driver-assist system that is intended to rival Autopilot. The American electric car maker also requested access to clones of hard drives from Xpeng senior executives. 

Interestingly enough, Tesla also requested access to court records related to a criminal charge against former Xpeng employee Zhang Xiaolang, who used to work for Apple. Like Cao, the former Apple employee is accused of stealing trade secrets before joining Xpeng. Unfortunately for Zhang, the Chinese EV maker opted to cut ties with him after criminal charges were filed.

It is these requests that were denied by a federal judge on Wednesday. In an announcement, US District Judge Vince Chhabria stated that the relevance of materials related to Zhang and Tesla’s claims against Cao was “speculative and tenuous.” “Discovery of this information is not proportional to the needs of this case at this time, especially given the potential for interference with an ongoing criminal prosecution, a concern raised by the US Attorney,” the US federal judge wrote, as noted in a TechNode report.

Apart from these, Tesla will also not be provided with images of work computers from several key Xpeng executives, including CEO He Xiaopeng and President Brian Gu. This was due to the executives being employed solely by China-based Xpeng Motors, not by the company’s US-based XMotors business unit. Tesla is not coming out of its requests empty handed, however. Xpeng is still required to produce the source code for its XPilot system. The source codes from XPilot and Autopilot are poised to be reviewed by a neutral third party, who will determine if any theft was indeed performed. 

Xpeng has been pretty open about the fact that its business is inspired by Tesla, with the company stating that had used the American electric car maker’s patents to develop its vehicles. Its P7 sedan, which was recently revealed, is also poised to be a response to the Model 3, Tesla’s most successful car to date. Unfortunately, some of Xpeng’s actions in the past have suggested that the company’s inspirations from Tesla may go a bit deeper than expected. This is hinted at by the heavily Model S/X inspired interior of its vehicles, and the fact that its website seems to be a direct copy of Tesla’s configurator.

Tesla Full Self-Driving v14.3.5 Early Impressions: new features and early performance

Tesla rolled out Full Self-Driving (Supervised) v14.3.5 yesterday, and about fifty miles of driving on the new version has given me enough time to highlight what seems to be strong about the release and what is not.

Additionally, Tesla has added a few new features with this specific update, which we’ll highlight as well.

Tesla Full Self-Driving v14.3.5 Performance

The new update is business as usual. Things seem to be running completely normal and necessary, but there are a few things that we’ve seemed to pick up on based on our own experience with v14.3.5, as well as what other users are seeing.

Initially, it seems to be more aware of its surroundings, making moves that are incredibly courteous to other drives and operating just a tad more reserved than what the suite might have done previously.

We had two instances where it showed this, the first being FSD needing to pass a Flagger Force vehicle that was placing down signage for the day. Their work truck was right at the front corner of a right-hand turn; typically where most cars travel when they take that turn.

FSD v14.3.5 recognized this, slowed down, and took the turn wide with no issues:

Additionally, v14.3.5 backed up for a semi truck that was making a wide turn onto a road my car was on. This is not new, but it seemed to be backing up for courtesy; it didn’t seem completely necessary, but it might have put some peace of mind in the truck driver’s head:

X user Mike P, also a Pennsylvania native like myself, shared three clips of his Tesla running v14.3.5 performing similar maneuvers. He said:

“FSD turns right into a small alley that only fits one car at a time, sees oncoming car, reverses out of alley to make space, realizes oncoming car is actually parking, re-enters alley.”
Check it out here:

It seems like Speed Profiles are still in need of some tweaking; I am adjusting what Speed Profile I’m in frequently, constantly changing it to get it to travel at the correct speed. This was an issue for me on v14.3.4. It seems like they’re just a little inconsistent.

Terrible Parking

Parking attempts on v14.3.5 were not good. There are quite a few people who have said this:

David Moss, the Tesla owner who has taken multiple coast-to-coast drives without any interventions, also has had some issues with parking early on with v14.3.5:

New Features

Tesla has added the ability to open Camera Preview at any time. Previously, it was only available in Park. Here’s what that feature looks like in action:

Check back later this week for a longer review of what we’ve noticed on Full Self-Driving v14.3.5.

Tesla makes the cut on California’s newest EV Rebate program

California just signed a $270 million EV rebate into law and it starts this summer.

California Governor Gavin Newsom signed SB 168 into law on Monday, July 13, 2026, creating a $270 million EV rebate program that delivers money directly at the dealership rather than as a tax credit applied months later. The program, called MyFirstEV, is funded equally by California’s state budget and participating automakers, with each contributing $135.5 million to make the math work.

The timing is directly tied to the loss of federal support when the $7,500 federal EV tax credit ended, removing the most significant consumer incentive that had driven EV adoption in the U.S. California, which accounts for roughly one-third of all EVs sold nationally, moved to fill that gap with a state-level replacement.

The rebate structure is straightforward. First-time EV buyers can receive $3,500 off any new battery-electric vehicle with an MSRP up to $50,000. Used EVs priced at $25,000 or below qualify for a $1,750 rebate. The credit is applied at the point of sale, which removes the friction of the old federal system where buyers had to wait for tax season to see the benefit. The program goes live later this summer, with the California Air Resources Board expected to release full participation details next month.

For Tesla buyers, the implications are mixed. The Tesla Model 3 RWD at $42,490 and the Model 3 Long Range at $47,490 both fall under the $50,000 cap and would qualify for the full $3,500 rebate for first-time buyers. The Model Y, which starts at $44,990 after Tesla’s recent price adjustment, also qualifies. The Model X, Model S, and Cybertruck all exceed the cap and receive no benefit. As Teslarati has reported, the program also includes a carve-out exempting California-based automakers like Rivian and Lucid from the price cap entirely, a provision that puts Tesla at a disadvantage since it relocated its headquarters to Texas in 2021.

Other qualifying vehicles include the Chevrolet Equinox EV, Ford Mustang Mach-E, Hyundai Ioniq 5, Kia EV6, and Volkswagen ID.4.

Tesla Semi enters new Pilot Program with interesting challenge

The Tesla Semi is entering a new Pilot Program with Paper Transport, LLC (PTI), a Wisconsin-based transportation provider. The company will test the Semi’s Long Range configuration through “dedicated operations within the Chicago market.”

Chicago presents an interesting challenge for the Semi, as it will be a colder-weather climate that will test the Semi’s ability to operate in lower temperatures and in potentially large accumulations of snow. This is something Tesla has been testing with the Semi in Alaska and even in Northern California during the colder months, but Chicago will present a truly tough midwestern winter.

PTI says it is using the Semi to evaluate its strategy of reducing transportation emissions while maintaining performance, reliability, and cost efficiency. These are major arguments for the Semi being introduced into new fleets.

CEO of PTI Tyler Ellison said:

“PTI has been a leader in sustainable transportation solutions for over 15 years. We take a consultative approach to helping customers identify and implement the right transportation solution for their network. Our partnership with Tesla expands our portfolio alongside renewable natural gas and intermodal, giving customers more ways to reduce Scope 3 emissions without compromising service or economics.”

PTI is far from the first company to adopt the Semi within a fleet, as Tesla entered strategic agreements with PepsiCo. and its subsidiary Frito-Lay for a Pilot Program that extended throughout the California region.

Tesla has let companies like those utilize the Semi to determine whether it would be suitable for their operations. Additionally, Tesla gets valuable information regarding the Semi’s performance, knowing what to improve and what is ideal for companies that will utilize the all-electric truck for regional and nationwide logistics.

PTI plans to utilize the Long Range configuration, which is priced at $290,000 and features a range of approximately 500 miles, a three-motor powertrain, up to 800 kW of drive power, and consumption of just 1.7 kWh per mile.

VP of Maintenance at PTI, Bryan Ellen, added:

“We are excited to partner with Tesla, leveraging their ever-evolving technology. We are bullish in our estimation of the parallels available between our dedicated model and the efficiency of their fully electric Class 8 tractor. We anticipate a growing synergy between our businesses as we work to facilitate this sustainable solution for our customers.”

PTI has logged more than 87 million miles using sources like compressed and renewable gas, but now is looking to take it a step further with fully electric operations.
