The Tesla AI team successfully rolled out FSD (Supervised) for the Cybertruck this weekend. While the system has mostly been released to company employees and early access testers, the first videos of FSD (Supervised) V12.5.5 on the Cybertruck are starting to get shared online. Based on comments from Cybertruck owners so far, it would appear that FSD (Supervised) is working fairly well on the all-electric pickup truck.
Tesla Director of Autopilot Software Ashok Elluswamy noted in a post on social media platform X that the Cybertruck is the first Tesla to receive end-to-end highway driving. Release notes shared online also revealed that the Cybertruck’s FSD came with vision-based attention monitoring with sunglasses.
Among the Tesla community members whose Cybertrucks received the FSD (Supervised) update are longtime Full Self-Driving testers Whole Mars Catalog and Dirty Tesla, both of whom have been testing the advanced driver-assist system for years. Based on the two FSD veterans, it appears that the Cybertruck’s FSD (Supervised) system features a number of interesting characteristics.
The first early access build of Cybertruck FSD is out! I went for a drive from Beverly Hills to Santa Monica with @BLKMDL3 and @___alexys___ to see how it performs.

During a drive from Beverly Hills to Santa Monica in California, longtime FSD tester Whole Mars Catalog observed that the Cybertruck’s FSD system behaved just like FSD in Tesla’s other vehicles, though it needs more tuning for the larger size of the all-electric pickup truck. The Cybertruck owner also noted that FSD (Supervised) was able to make tight lane changes properly, but the system does not work in trailer mode yet.
Here’s my summary/review of FSD for Cybertruck tonight thanks to @WholeMarsBlog for the ride.
For the first FSD release it was great + better than we expected it to be. It did some things super well like having smooth turns and very smooth braking.

Fellow Tesla owner @BLKMDL3, who was with the longtime FSD tester during the Cybertruck FSD (Supervised) drive, observed that the visuals on the vehicle’s infotainment display were extremely smooth. He also noted that the Cybertruck’s FSD system displayed some smooth turning and breaking behaviors. The vehicle, however, reportedly moved a bit slow on the highway, and there were some quirks that needed ironing out.
Here’s the only mistake I saw FSD make so far in Cybertruck, but I did see it two separate times – making too sharp of a left turn.

FSD veteran Dirty Tesla, for his part, opted to test the Cybertruck’s FSD (Supervised) system during a nighttime drive in Michigan. The Tesla owner observed that corrections using the Cybertruck’s steer-by-wire system were very natural and smooth. He also observed that the vehicle was able to stay in lane, perform lane changes, and exit the highway fairly well. The vehicle, however, did require a few interventions during the drive.

Overall, the Tesla Cybertruck’s FSD (Supervised) system seems to be a pretty solid update to the all-electric pickup truck, though it is understandable that it is still only being released to early access testers. Considering how good this initial FSD (Supervised) version is on the Cybertruck, however, it would be very exciting to see just how much better the vehicle’s advanced driver-assist system could get in the coming months.

Tesla Cybercab tests are going on overdrive with production-ready units
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the vehicle being reported across social media this week.
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the autonomous two-seater being reported across social media this week. Based on videos of the vehicle that have been shared online, it appears that Cybercab tests are underway across multiple states.
Recent Cybercab sightings
Reports of Cybercab tests have ramped this week, with a vehicle that looked like a production-ready prototype being spotted at Apple’s Visitor Center in California. The vehicle in this sighting was interesting as it was equipped with a steering wheel. The vehicle also featured some changes to the design of its brake lights.
The Cybercab was also filmed testing at the Fremont factory’s test track, which also seemed to involve a vehicle that looked production-ready. This also seemed to be the case for a Cybercab that was spotted in Austin, Texas, which happened to be undergoing real-world tests. Overall, these sightings suggest that Cybercab testing is fully underway, and the vehicle is really moving towards production.
Production design all but finalized?
Recently, a near-production-ready Cybercab was showcased at Tesla’s Santana Row showroom in San Jose. The vehicle was equipped with frameless windows, dual windshield wipers, powered butterfly door struts, an extended front splitter, an updated lightbar, new wheel covers, and a license plate bracket. Interior updates include redesigned dash/door panels, refined seats with center cupholders, updated carpet, and what appeared to be improved legroom.
There seems to be a pretty good chance that the Cybercab’s design has been all but finalized, at least considering Elon Musk’s comments at the 2025 Annual Shareholder Meeting. During the event, Musk confirmed that the vehicle will enter production around April 2026, and its production targets will be quite ambitious.

Tesla gets a win in Sweden as union withdraws potentially “illegal” blockade
As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.
Swedish union Vision has withdrawn its sympathy blockade against Tesla’s planned service center and showroom in Kalmar. As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.
Vision’s decision to pull the blockade
Vision announced the blockade in early December, stating that it was targeting the administrative handling of Tesla’s facility permits in Kalmar municipality. The sympathy measure was expected to start Monday, but was formally withdrawn via documents sent to the Mediation Institute and Kalmar Municipality last week.
As noted in a Daggers Arbete report, plans for the strike were ultimately pulled after employer group SKR highlighted potential illegality under the Public Employment Act. Vision stressed its continued backing for the Swedish labor model, though Deputy negotiation manager Oskar Pettersson explained that the Vision union and IF Metall made the decision to cancel the planned strike together.
“We will not continue to challenge the regulations,” Petterson said. “The objection was of a technical nature. We made the assessment together with IF Metall that we were not in a position to challenge the legal assessment of whether we could take this particular action against Tesla. Therefore, we chose to revoke the notice itself.”
The SKR’s warning
Petterson also stated that SKR’s technical objection to the Vision union’s planned anti-Tesla strike framed the protest as an unauthorized act. “It was a legal assessment of the situation. Both for us and for IF Metall, it is important to be clear that we stand for the Swedish model. But we should not continue to challenge the regulations and risk getting judgments that lead nowhere in the application of the regulations,” he said.
Vision ultimately canceled its planned blockade against Tesla on December 9. With Vision’s withdrawal, few obstacles remain for Tesla’s long-planned Kalmar site. A foreign electrical firm completed work this fall, and Tesla’s Careers page currently lists a full-time service manager position based there, signaling an imminent opening.

Tesla Semi program Director teases major improvements
Tesla Semi Program Director Dan Priestly teased the major improvements to the all-electric Class 8 truck on Thursday night, following the company’s decision to overhaul the design earlier this year.
Priestley said he drove the Semi on Thursday, and the improvements appear to be welcomed by one of the minds behind the project. “Our customers are going to love it,” he concluded.
Just drove the redesigned Semi. Our customers are going to love it. https://t.co/KZ88sf1CDL

The small detail does not seem like much, but it is coming from someone who has been involved in the development of the truck from A to Z. Priestley has been involved in the Semi program since November 2015 and has slowly worked his way through the ranks, and currently stands as the Director of the program.
Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
Tesla made some major changes to the Semi design as it announced at the 2025 Annual Shareholder Meeting that it changed the look and design to welcome improvements in efficiency.
Initially, Tesla adopted the blade-like light bar for the Semi, similar to the one that is present on the Model Y Premium and the Cybertruck.
Additionally, there are some slight aesthetic changes to help with efficiency, including a redesigned bumper with improved aero channels, a smaller wraparound windshield, and a smoother roofline for better aero performance.
All of these changes came as the company’s Semi Factory, which is located on Gigafactory Nevada’s property, was finishing up construction in preparation for initial production phases, as Tesla is planning to ramp up manufacturing next year. CEO Elon Musk has said the Semi has attracted “ridiculous demand.”
The Semi has already gathered many large companies that have signed up to buy units, including Frito-Lay and PepsiCo., which have been helping Tesla test the vehicle in a pilot program to test range, efficiency, and other important metrics that will be a major selling point.
Tesla will be the Semi’s first user, though, and the truck will help solve some of the company’s logistics needs in the coming years.
