Tesla is now in talks with the city of Palo Alto regarding the launch of its Robotaxi service in the city. According to Palo Alto Online, the city has already held a preliminary meeting with Tesla to discuss a potential partnership.
The city of Palo Alto has been looking for an alternative transport option for its citizens, as the free Palo Alto Shuttle ceased operations in 2020. Palo Alto currently has a rideshare carpool service called ‘Link,’ which offers citizens a cheaper alternative to Uber.
Advantages for Palo Alto
Robotaxi could offer the citizens of Palo Alto an excellent alternative means of transportation. They’d be able to summon their own Cybercab for their trip rather than waiting for a pooled form of transportation like Link.
The best part is that Robotaxi, with its extremely low cost per mile, is likely to also cost the residents less while also being more convenient and more widely available. This could be a massive advantage for its residents, who were previously relying on the free shuttle network and now use the fairly inexpensive but somewhat inconvenient Link service.
Robotaxi Testing Grounds
This deal with Palo Alto could represent an excellent opportunity for Tesla to gather additional data and start testing their autonomous taxi service. However, the City of Palo Alto confirmed that “the potential Tesla deal won’t be realized for some time because of regulatory hurdles.” Tesla will need to work with two California bodies to get this off the ground.
Before this Palo Alto plan can get off the ground, the Robotaxi service will have to be approved by the California Public Utilities Commission, and the Cybercab will also have to be approved by the California Department of Motor Vehicles before it can be used. Once regulatory approval is granted, Tesla will likely begin working in earnest to get their Robotaxis off the ground.
During its Robotaxi event, Tesla announced that it plans to start its Robotaxi service with Model 3 and Model Y vehicles in 2025, with the Cybercab entering the picture in late 2026. It’s not clear whether this potential deal keeps this timeline on track or helps expedite it.
Getting the Robotaxi service off the ground in a small location will be an excellent opportunity for Tesla to refine the overall experience, from the Robotaxi app, which is expected to be a separate riding-sharing app, to the user interface in the Robotaxi.
Tesla will also need to continue developing its automated charging and cleaning hubs, which will undoubtedly need to be refined and adjusted as it gets tested in the real world.
The next two years will undoubtedly be very interesting years for Tesla, as they’ll be facing the biggest steps of regulatory approval for both Unsupervised FSD, as well as Robotaxi.
Tesla’s Cybertruck has officially earned a 5-Star Safety Rating from the NHTSA—an impressive achievement given the vehicle’s design. The achievement demonstrates Tesla’s engineering prowess. As one engineer points out, it wasn’t an easy feat.
Interestingly, the NHTSA only recently disclosed the results, despite the crash tests being completed a while ago. According to Lars Moravy, Tesla’s VP of Vehicle Engineering, the team had been aware of the 5-star rating for quite some time. While the reason for the delay remains unclear, now that the results are public, Tesla’s engineers can finally share how they achieved the rating.
Crumple Zones
Wes Morril, the Cybertruck’s Lead Engineer, wrote about the crash test video on X recently, addressing the claims that the Cybertruck doesn’t have a crumple zone. He also posted a side-by-side video (below) of the engineering analysis and the crash test itself.
Engineered Crash Safety
There’s a lot of engineering precision at play when a Cybertruck is involved in a crash. Unlike traditional crash structures that rely on crash cans and collapse points, the Cybertruck’s front gigacasting is designed to absorb and redirect impact forces in a highly controlled manner.
It all starts with the bumper beam, which crushes within the first few milliseconds of a high-speed impact. At the same time, the vehicle’s sensors rapidly analyze the crash dynamics and determine the optimal deployment of safety restraints, including airbags and seat belt pre-tensioners. These split-second actions are crucial in keeping occupants safe.
As the crash progresses, the vehicle’s structure deforms in a carefully engineered sequence. The drive unit cradle bends, directing the solid drive unit downward and out of the way, allowing the gigacasting to begin absorbing impact forces.
The casting crushes cell by cell, methodically dissipating energy in a controlled manner. This gradual deceleration reduces the g-forces transferred to occupants, making the crash much less severe. As the gigacast begins crushing, the safety restraints are deployed.
As Wes points out in his post - you can see how accurate the virtual analysis and modeling were. The video shows the simulated crash side by side with the real-life crash test and they’re almost identical. All that virtual testing helps provide feedback into the loop to design a better and safer system - one that is uniquely different than any other vehicle on the road.
All the armchair experts claimed the Cybertruck has no crumple zone and I get it, the proportions seem impossible. It was a tough one and there is a lot of engineering that went into it. Let me break it down for you:
Tesla has pioneered the use of single-piece castings for the front and rear sections of their vehicles, thanks to its innovative Gigapress process. Many automakers are now following suit, as this approach allows the crash structure to be integrated directly into the casting.
This makes the castings not only safer but also easier to manufacture in a single step, reducing costs and improving repairability. For example, replacing the entire rear frame of a Cybertruck is estimated to cost under $10,000 USD, with most of the expense coming from labor, according to estimates shared on X after high-speed rear collisions.
These insights come from Sandy Munro’s interview (posted below) with Lars Moravy, Tesla’s VP of Vehicle Engineering, highlighting how these advancements contribute to the improvements in Tesla’s latest vehicles, including the New Model Y.
However, with the new Model Y, Tesla has decided to go a different route and eliminated the front gigacast.
No Front Casting
Tesla’s factories aren’t equipped to produce both front and rear castings for the Model Y. Only Giga Texas and Giga Berlin used structural battery packs, but these were quickly phased out due to the underwhelming performance of the first-generation 4680 battery.
Tesla has gone back to building a common body across the globe, increasing part interchangeability and reducing supply chain complexity across the four factories that produce the Model Y. They’ve instead improved and reduced the number of unique parts up front to help simplify assembly and repair.
There is still potential for Tesla to switch back to using a front and rear casting - especially with their innovative unboxed assembly method. However, that will also require Tesla to begin using a structural battery pack again, which could potentially happen in the future with new battery technology.
Rear Casting Improvements
The rear casting has been completely redesigned, shedding 7 kg (15.4 lbs) and cutting machining time in half. Originally weighing around 67 kg (147 lbs), the new casting is now approximately 60 kg (132 lbs).
This 15% weight reduction improves both vehicle dynamics and range while also increasing the rear structure’s stiffness, reducing body flex during maneuvers.
Tesla leveraged its in-house fluid dynamics software to optimize the design, resulting in castings that resemble organic structures in some areas and flowing river patterns in others. Additionally, manufacturing efficiency has dramatically improved—the casting process, which originally took 180 seconds per part, has been reduced to just 75 seconds, a nearly 60% time reduction per unit.

Tesla’s new casting method incorporates conformal cooling, which cools the die directly within the gigapress. Tesla has been refining the die-casting machines and collaborating with manufacturers to improve the gigapress process.
In 2023, Tesla patented a thermal control unit for the casting process. This system uses real-time temperature analysis and precise mixing of metal streams to optimize casting quality. SETI Park, which covers Tesla’s manufacturing patents on X, offers a great series for those interested in learning more.
The new system allows Tesla to control the flow of cooling liquid, precisely directing water to different parts of the die, cooling them at varying rates. This enables faster material flow and quicker cooling, improving both dimensional stability and the speed of removing the part from the press for the next stage.
With these new process improvements, Tesla now rolls out a new Model Y at Giga Berlin, Giga Texas, and Fremont every 43 seconds—an astounding achievement in auto manufacturing. Meanwhile, Giga Shanghai operates two Model Y lines, delivering a completed vehicle every 35 seconds.
