Tesla Model S police cruiser not to blame for mishap, says Fremont PD
The Fremont Police Department released a statement on Thursday evening clarifying reports that its Tesla Model S cruiser ran out of battery during a high-speed pursuit on Interstate 680.
On Monday, the Tesla Model S gained national attention as a journalist contacted the department requesting information regarding a high-speed chase from the Irvington District of Fremont, California to Washington Boulevard. The chase eventually ended up on Interstate 680, heading south toward San Jose, CA. The journalist released a portion of the police scanner recordings from the chase, where the officer driving the Model S told other units in the pursuit that he would have to abandon due to his battery running low.
However, the suspect then drove onto the shoulder of the interstate, passing a vehicle in an increasingly unsafe manner. The Sargeant of the Fremont PD then made the decision to halt the pursuit of the vehicle as it was becoming more of a public safety risk. All three police units disengaged the vehicle, and the chase was stopped after about 10 miles.
When the Sargeant made the announcement to stop pursuing the vehicle, the Tesla Police Cruiser was at a nearby charging station. The statement from the Fremont PD stated, “at no time did the battery of the Tesla become a factor in our ability to pursue the suspect or perform our duties. This situation, while embarrassing, is no different from cases where a patrol car runs low (or even dry) of fuel.”
Fremont’s statement noted that the journalist who released the initial story contacted the department with questions and subsequently published the article. It reached the national spotlight due to public interest. Fremont Police were sure to clarify the fact that the Tesla having to drop out of the chase could have happened to any vehicle and that they recommend each officer have at least half of a tank of gas or half a battery charge when they begin their shift. “While not policy, we recommend officers begin their shift with at least a half tank of gas or in this case, a battery charge of 50%. On this date, our officer driving the Tesla noted approximately 50% of battery life when he began his shift,” they said. The fact that the vehicle had to stop was in no way the fault of the Model S.
In fact, the department has been so pleased with their Tesla cruiser, they have already had initial talks about buying a second vehicle, most likely a Model X. “So far, the vehicle is performing extremely well, and has exceeded our expectations. We are already in initial conversations about testing a second vehicle, likely an SUV model, and we look forward to providing our initial results in the near future,” Captain Sean Washington said.
The Fremont PD stated that their Model S police cruiser has outperformed their expectations and they are extremely happy with its performance, as they have tracked the performance of the vehicle since its induction into the police force. “Over the last six months, data on range, performance, equipment, and other elements has been gathered by officers through its use as a patrol vehicle. During this time we have documented two police pursuits, where the vehicle met and exceeded expectations.”
Fremont is the location of the original Tesla Factory. The company bought the facility in 2010. Previously, it was the home of General Motors from 1962 to 1982 and eventually, Toyota also produced vehicles there. Tesla and Toyota worked conjunctively to work toward producing electric vehicles. Tesla officially opened the factory as its own on October 27, 2010.
Read the full statement from the Fremont Police Department below:
Our Department has unfortunately been in the news this week for an incident involving our electric police patrol vehicle (Tesla Model S). We first deployed the Tesla in March of this year as a fully outfitted patrol vehicle. Over the first six months, the performance feedback and initial data collection has been very positive and we are in early discussions of expanding the program. During a pursuit last Friday night, the battery charge began to run low, and we’d like the opportunity to clarify and provide additional context with regard to what occurred.
On Friday afternoon, a patrol officer checked out our Tesla patrol vehicle at the start of his shift and noticed the battery was half-charged. A typical battery at full charge ranges from 220-240 miles and during an 11 hour patrol shift, Fremont patrol officers drive approximately 70-90 miles. While not policy, we recommend officers begin their shift with at least a half tank of gas or in this case, a battery charge of 50%. On this date, our officer driving the Tesla noted approximately 50% of battery life when he began his shift. While the vehicle is routinely charged between shifts, on Friday the vehicle had just been returned from our Corporation Yard. The vehicle is regularly returning at the end of every shift with 40-60%, if not more, of the battery charge remaining.
Nine hours into the officer’s shift, at 11:05 p.m., he became involved in a vehicle pursuit that lasted a total of 8 minutes. The pursuit began in our Irvington District and traveled on Washington Blvd., before merging southbound onto I680 towards San Jose. Within minutes, two additional Fremont patrol units were behind the Tesla and in the pursuit. Additionally, the California Highway Patrol (CHP) was notified and responding. As standard protocol, once CHP has sufficient units, they take over our pursuits on the freeway.
The pursuit spanned approximately 10 miles and at times exceeded 110 mph. Regular updates regarding the speed, location, general traffic and roadway conditions were provided by the second officer in the pursuit. Just before the pursuit ended at 11:13 p.m., the officer driving the Tesla responsibly notified his cover units he was going to have to back out of the pursuit because his battery was running low. Just after they passed the Montague Expressway exit, the suspect drove on the left shoulder of the road to pass a vehicle. At that time, the Fremont Police Sergeant monitoring the pursuit gave orders to terminate to ensure public safety. All three units deactivated their emergency equipment and returned to normal driving conditions. At that point, the Tesla was driven to a nearby charging station and the additional Fremont units returned to the City. CHP located the unoccupied vehicle in the area of I680 and the Berryessa exit. At no time did the battery of the Tesla become a factor in our ability to pursue the suspect or perform our duties. This situation, while embarrassing, is no different from cases where a patrol car runs low (or even dry) of fuel.
In recent years police radio traffic has become readily accessible through phone applications and its common practice for news media and even community members to monitor and even record. On Monday, a local journalist contacted our Department requesting additional details regarding the pursuit. The journalist subsequently wrote an article and released a portion of our radio traffic. Since that time, the Department has received numerous media inquiries regarding the vehicle’s battery. Unfortunately, public interest in the original story propelled it into the national spotlight.
Over the last six months, data on range, performance, equipment, and other elements has been gathered by officers through its use as a patrol vehicle. During this time we have documented two police pursuits, where the vehicle met and exceeded expectations. Our final results and data will ultimately help us determine if the EV technology meets current patrolling applications and cost effectiveness. We remain dedicated to our continued research into the benefits of using electric vehicles and the effects they have on our environment. We hope to share our initial data and feedback soon.
Captain Sean Washington stated, “So far, the vehicle is performing extremely well, and has exceeded our expectations. We are already in initial conversations about testing a second vehicle, likely an SUV model, and we look forward to providing our initial results in the near future.”

How Tesla’s Roadster fan system and thrusters are built to dominate the corners
Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.
Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.
That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY

Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.
Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

These aero features aren’t just for looks: they provide the best passive downforce package of any road car (approaching F1 levels!) with wing actuation driven by the @Tesla_Optimus actuator system https://t.co/AqrC4qUga9

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”
There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
Tesla’s Roadster comes in Performance, Thrust and Rocket versions, with a claimed 0-60 under 0.59 seconds.
Tesla finally showed the next generation Roadster on Thursday night, and the demo had more in common with a SpaceX test than a track lap. At an event outside Waco, Texas, near SpaceX’s McGregor site, the car used a mix of fans and cold gas thrusters to drive up a curved ramp until it was upside down, then flew off, flipped and landed on the pavement. “Well, it worked,” Elon Musk said. “Flying cars are real.”
The Roadster also hovered itself over a Cybercab, Cybertruck, Tesla Semi, Model Y and Model 3 while moving, and that Tesla showed it going 0 to 60 mph in one second. Musk said “this will be the actual car that’s on the roads” and that it “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. He called the result a collaboration between Tesla and SpaceX engineers that is “better than any James Bond car,” with Franz von Holzhausen and Lars Moravy on site.
Tesla published new mind-blowing stats for the car that replace the previous targets. The Performance version is road ready and seats two, with active aerodynamics and a multi-mode suction system, and Tesla lists 0 to 60 mph in under 1.6 seconds. The Thrust version is race ready, also seats two, and adds rear-mounted cold gas thrusters for a 0 to 60 time of under 0.9 seconds. The Rocket version is described as air ready, seats one, and uses perimeter-mounted thrusters for forward and upward acceleration plus lateral rotational movement.
| Configuration | Seats | 0 to 60 mph |
|---|---|---|
| Performance | 2 | under 1.6 s |
| Thrust | 2 | under 0.9 s |
| Rocket | 1 | under 0.59 s |
Tesla’s own description: “So…yes, it can fly.” It lists a 0 to 60 time of under 0.59 seconds for Rocket, a top speed of up to more than 230 mph, and range of more than 300 miles. Tesla has not yet given pricing in the information we have seen, but has reopened $50,000 reservations in the newly updated Tesla Roadster configurator. Production is planned for Giga Texas in 2027 or 2028, and Musk has said it would follow the demo by 12 to 18 months.
Every car on the road today is limited by one thing: tire grip
Roadster’s thruster system generates 4–5x the force the tires can.
More force on the same mass means significantly better acceleration – physics does the rest https://t.co/zdPRT2aKwZ

Tesla’s Roadster page adds more on how the car works. A multi-mode fan and ground sealing system pulls air from under the car, producing enough suction to hold it upside down even when stationary. Active wings, steer-by-wire with a yoke, and a Track Mode that lowers the car round out the driving setup. The cold gas thrusters use all-electric actuators for micro adjustments to stabilize the car in flight. Tesla says it cut weight with magnesium, titanium and carbon fiber, manual controls and a fixed seat position, and the exterior has hidden headlights, a full-length taillight and Ano White paint inspired by aerospace coatings. Inside are an Ultrawhite interior with gray microsuede, a center touchscreen and two smaller forward displays, and gold tinted glass modeled on spacesuit visors. Availability is tiered: Performance is by reservation, Thrust is a limited release, and Rocket is invite only. Tesla notes the car is not approved for public road use, and that Rocket is not available in all regions.

Musk has described the Roadster as “the best of the last of the human-driven cars,” and he has been open that it is a halo product. He said he is “not sure it moves the needle massively from a revenue standpoint,” and has warned that anyone whose top priority is safety should not buy it. Tesla reports third quarter earnings on October 21.

Amazon shuts out Elon Musk’s Grok Bot so he may just build his own rival store
Musk promises SpaceX will cover Grok Bot purchase errors, tells users to shop beyond Amazon.
Elon Musk said SpaceX will reimburse users if Grok Bot botches a purchase or leaks their card details. A few hours later he was telling users to take their shopping elsewhere after Amazon shut the agent out.
The first post was a reply to an X user who said Grok Bot booked him a flight after he sent a photo of his credit card. “This works well,” Musk wrote. “If Grok @Bot makes a mistake with a purchase or leaks your card (never happened yet), SpaceX will make you whole,” said Musk.
The second came after another user posted the error his Grok Bot hit on Amazon: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.” The user said his bots can no longer order from the site. Musk answered, “Just ask Grok @Bot to buy what you want someplace else and get a better deal. There are far more purchasing websites than just Amazon!” He later added, “Maybe we should start a competitor to Amazon,” a possible hint at an X shopping service.
Just ask Grok @Bot to buy what you want someplace else and get a better deal.
There are far more purchasing websites than just Amazon!
— Elon Musk (@elonmusk) October 15, 2026
The Amazon block did not start Thursday. A reply to Musk on October 10 said Amazon was blocking the bot, and Musk responded that Grok would find another way, then showed an order it placed on Lego’s website.
The latest reimbursement promise builds on late August when Musk told a Tesla investor weighing whether to give Grok Bot access to his bank accounts, “If Grok Bot messes up, we will make you whole,” as Teslarati covered when SpaceXAI added its Finance integration. That promise goes further than the company’s consumer terms, which make users responsible for what their agents do and generally cap liability at the greater of fees paid or $100. Neither Thursday post says those terms have changed, so for now it remains a statement on X rather than a published policy.
The two posts matter to Tesla owners because Grok Bot is no longer limited to a phone. Tesla brought it into its vehicles on September 22, and it is now enabled across every Cybercab and the rest of the Model Y Robotaxi fleet, as noted when Teslarati looked at why Grok Bot may be the Cybercab’s real advantage. A rider who asks for groceries or a coffee order is relying on retailers that let the agent in. Amazon has now said it will not, and Musk’s answer is to route around it.
Amazon has not commented publicly on the block in the posts Teslarati reviewed, and it is unclear whether Musk will follow through on a rival store.
So, how many of you do the vast majority of shopping on Amazon and hate that you do? Comment and let us know your thoughts!
