Those of us who paid for Full Self-Driving but who were not included in the initial test groups, Tesla employees and carefully selected customers, will get access to the BUTTON on Friday, September 24th.
But the BUTTON doesn't mean that you will be added to the widened group of beta testers. You have to earn it. Here's how.
This article is likely of interest only to people who paid for FSD, are in the US and who want to volunteer to teach the computer how to drive. I want to stress that this is a volunteer job. You won't earn a penny for doing this.
Pushing the button is not enough. You have to agree to allow Tesla insurance to absorb data from your driving for a week. Then Tesla will decide if it wants you in the expanded group of beta testers.
Remember, becoming a beta tester doesn't mean that your car can drive itself without your intervention. Quite the reverse. Tesla is looking for volunteers who will teach the neural network how to drive like a professional chauffeur. That's professional chauffeur, not professional race car driver.
Factors Tesla Insurance Uses
Luckily for us, a while back Reddit user /u/Callump01 reverse engineered the Tesla app to determine exactly which events Tesla uses when determining a driver's safety rating.
Callump01 was able to determine that Tesla uses these metrics when determining a driver's premium:
ABS Activation - Number of times ABS is activated
Hours Driven - Average daily driving time
Forced Autopilot Disengagements - Number of times Autopilot is disabled due to ignored alerts
Forward Collision Warnings - Number of times car detects a potential forward collision
Unsafe Following Time - Portion of time spent at an unsafe following distance
Intensity of Acceleration and Braking - Speed variance due to extreme acceleration and braking. Shown on a scale from 0-10 as measured against Tesla's internal fleet.
So here's what to do during the week where you are being evaluated by the insurance software.
Drive places. If your car is parked all the time, the software won't be able to assess your driving skill.
Engage FSD whenever possible. Tesla will want to recruit volunteers who are actually interested in using FSD. Elon Musk has said that someone who uses Autopilot would fall into the “good" category.
Drive on city streets and country roads. Autopilot is already pretty good at driving on limited access highways.
Don't accelerate aggressively unless you must do so to avoid a crash. Insurance algorithms don't like aggressive drivers.
Reduce ABS Usage
Focus far ahead. One of the statistics that is kept is the number of times ABS was activated. Reducing this number shows less aggressive driving. If you see that you are going to have to stop for a light or a stop sign, tap the brake to go out of FSD so you can slow down with regenerative braking. Insurance algorithms don't like aggressive braking, and, unfortunately, Tesla FSD, waits too long to slow down for signals and stop signs. Then it brakes aggressively. So using FSD to come to a stop will hurt your score.
Don't Accelerate Too Quickly
Don't speed very much. The Tesla insurance algorithm will look at your intensity of acceleration in addition to braking. Sometimes, you have to go faster than the posted speed limit in order to keep up with traffic. If you are in a situation where all the traffic is going faster than the posted speed limit, then you can speed up a bit, but try to stay as close to the speed limit as you can without blocking traffic. Remember, if you have to speed, keep up with the slower speeders, not the faster speeders.
If the car is braking for no apparent reason, phantom braking, use the accelerator to move the car along.
If you are approaching a sharp curve there are two things you need to think about. Without the beta version of FSD, some curves are too sharp, and standard FSD will stop working in the middle of the curve. I've experienced this at certain curves in my area. If this happens, it will lower your score. So the two things to do are, first, lower your speed before the curve by tapping the brake, and second, steer the car around the curve yourself before re-engaging FSD.
When you're using Autopilot, pay attention to the alerts. Tesla will track the number of times that Autopilot has been disengaged.
Keep Your Distance
You'll also want to pay close attention to objects in front of your. Tesla will be looking at the number of times Forward Collision Warnings have gone off.
Use a follow distance greater than one or two. Another metric that Tesla insurance uses to measure how safe someone is driving is by their follow distance. If someone follows too closely for long periods of time, this will lower their Tesla insurance rating as well.
Obey traffic rules whenever possible. Yield the right of way when you don't have the right of way. Take the right of way when you do have it, but don't crash just because you are entitled to the right of way.
Be careful to yield to pedestrians and bicyclists. Even if you have the right of way, it will mess up your day if you hit a pedestrian or a bicyclist. And you won't get to be a beta tester for FSD.
After you activate the button on September 24th the Tesla insurance calculator will show your rating in real-time so that you can tell how you're driving and can adjust accordingly. It'll also provide additional details on what is rated a “good" driver.
Tesla insurance calculator will show status in real-time & tell you what actions are needed to be rated “good driver"
The button will be available this Friday, presumably in your car. Stay tuned for more details. Tesla FSD Beta 10.1 which is set be released on October 1st, will introduce new features such as merged NNs for highway and city driving, as well as the ability to go in reverse.

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.
