Tesla has officially started rolling out a new version of its insurance program’s Safety Scores beta, improving upon a few different metrics that make up the index.

As detailed on the Tesla Insurance web page, the company has updated its Safety Scores to beta version 2.2 from the previous version 2.1. The update primarily includes improvements to how Excessive Speeding is measured, along with the removal of Forward Collision Warnings (FCW) from the formula.

In addition, Tesla has slightly increased the values of related factors such as Hard Braking and Unsafe Following Time in the v2.2 formula, perhaps in an attempt to help accommodate some of the situations previously covered by the FCW rating.

Tesla’s Safety Scores are used to determine premium rates for buyers of the company’s in-house insurance program, except in California, where privacy laws prohibit the use of real-time driving data to determine premiums. The company also says that its latest formula for Safety Scores were generated using over 22 billion miles of fleet data from its cars, while the company plans to continue improving the formula as more data comes in.

At this time, Tesla Insurance is available in the following 12 states, though Safety Scores aren’t available in California for the aforementioned reason:

You can see the factors that make up Tesla’s Insurance Safety Scores below or on its website here, along with the specific formula that makes up a drivers’ 0 to 100 Safety Score.

Hard Braking

Hard braking is defined as backward acceleration, measured by your Tesla vehicle, in excess of 0.3g. This is the same as a decrease in the vehicle’s speed larger than 6.7 mph, in one second. Hard braking is introduced into the Safety Score Beta formula as the proportion of time where the vehicle experiences backward acceleration greater than 0.3g as a percentage of the proportion of time the vehicle experiences backward acceleration greater than 0.1g (2.2 mph in one second). Hard braking while on Autopilot is not factored into the Safety Score Beta formula. For vehicles with Autopilot computer 3.0 or greater, braking while the vehicle detects yellow traffic lights is also not factored into the Safety Score Beta formula. If the vehicle is unable to detect a yellow traffic light at the time of the hard braking, the event will impact your Safety Score. The percentage shown in the app is the proportion of time spent braking done with excessive force when driving and Autopilot is not engaged. The value is capped at 5.2 percent in the Safety Score Beta formula.

Aggressive Turning

Aggressive turning is defined as left/right acceleration, measured by your Tesla vehicle, in excess of 0.4g. This is the same as an increase in the vehicle’s speed to the left/right larger than 8.9 mph, in one second. Aggressive turning is introduced into the Safety Score Beta formula as the proportion of time the vehicle experiences left or right acceleration greater than 0.4g as a percentage of the proportion of time the vehicle experiences left or right acceleration greater than 0.2g (4.5 mph in one second). Aggressive turning while on Autopilot is not factored into the Safety Score Beta formula. The percentage shown in the Tesla app is the proportion of time spent turning with excessive force when driving and Autopilot is not engaged. The value is capped at 13.2 percent in the Safety Score Beta formula.

Unsafe Following

Your Tesla vehicle measures its own speed, the speed of the vehicle in front and the distance between the two vehicles. Based on these measurements, your vehicle calculates the number of seconds you would have to react and stop if the vehicle in front of you came to a sudden stop. This measurement is called “headway.” Unsafe following is the proportion of time where your vehicle’s headway is less than 1.0 seconds relative to the time that your vehicle’s headway is less than 3.0 seconds. Unsafe following is only measured when your vehicle is traveling at least 50 mph and is incorporated into the Safety Score Beta formula as a percentage. Unsafe following while on Autopilot is not factored into the Safety Score Beta formula. The percentage shown in the Tesla app is the percentage of unsafe following when driving and Autopilot is not engaged. The value is capped at 63.2 percent in the Safety Score Beta formula.

Excessive Speeding

Credit: Tesla

Excessive Speeding is defined as the proportion of time spent driving in excess of 85 mph or driving 20% faster than the vehicle in front of you, when that vehicle is going over 25 mph and is within 100 meters of your vehicle. This value is expressed as a percentage of total driving time and is capped at 10.0% in the Safety Score Beta formula. Speeding while on Autopilot is not factored into the Safety Score Beta formula.

Late-Night Driving

Late-Night Driving is defined as the number of seconds you spend driving at night (11 PM – 4 AM) divided by the number of seconds you spend driving total during the day and night. Due to the variable risk level associated with driving during each late-night hour, each hour is weighed differently, and driving at each hour will affect your Safety Score differently. For example, driving at 11 PM will not affect your Safety Score as heavily as driving at 2 AM. Drive sessions that span two days will apply to the day the trip ends. Late-Night Driving includes all driving at night (11 PM – 4 AM) including any driving done on Autopilot. The value is capped at 14.2 percent in the Safety Score Beta formula.

Forced Autopilot Disengagement

The Autopilot system disengages for the remainder of a trip after the driver has received three audio and visual warnings. These warnings occur when your Tesla vehicle has determined that the driver has not applied sufficient resistance to the steering wheel or has become inattentive. Forced Autopilot Disengagement is introduced into the Safety Score Beta formula as a 1 or 0 indicator. The value is 1 if the Autopilot system is forcibly disengaged during a trip, and 0 otherwise.

Unbuckled Driving

Unbuckled Driving is defined as the proportion of time spent driving above 10 mph without fastening the driver’s seatbelt in a Tesla vehicle, as a percentage of time spent driving above 10 mph. The value shown in the Tesla app is the proportion of time driven at a speed over 10 mph, without buckling the driver’s seatbelt, as a percentage of time spent driving over 10 mph. The value is capped at 31.7 percent in the Safety Score Beta formula.

Tesla’s formula for Safety Score beta v2.2

Tesla takes the formula pictured below, dubbed its Predicted Collision Frequency (PCF), and converts it into the 0 to 100 version 2.2 Safety Score it assigns based on driver behavior. The 2.1 Safety Score formula can also be seen on the Tesla Insurance page, though the below formula is for the newly launched version 2.2.

Tesla’s flying Roadster just revealed something bigger than the car

Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.

The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.

Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.

The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.

The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.


Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.

The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

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.


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.

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 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.

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.
