Tesla has started to use real accident data from its customers to improve the safety of their cars

It’s been a couple of years since we got to know the first details of the “Tesla Crash Lab”, A laboratory in which Tesla crashes its cars to test their safety before organisms such as American IIHS or Euro NCAP. Now, the brand has just revealed how they use it to test the latest technology in crash testing.

It is about collecting and using data from the millions of vehicles in its fleet through the sensors they incorporate for autonomous driving and reproducing scenarios of accidents that occurred in the real world, with the aim of increasing the safety of your vehicles.

How data can help

In the images we can see how this new technology works to carry out crash tests, explained by an engineer who works in the brand’s safety department, in Tesla’s own laboratory located in Fremont, California. To do this, they use a Tesla Model Y, an electric SUV with space for up to seven seats.

We have already seen how cars like the Model 3, which has earned five-star ratings in all categories and the lowest probability of injury ever demonstrated by the US National Highway Traffic Safety Administration (NHTSA); in addition to obtaining the ‘IIHS Top Safety Pick +’ award went to the Audi e-tron, which is the highest possible level of security granted by the American organization.

For crash tests, and like other brands, Tesla until now did computer simulations and created 3D components to recreate the crashes through a mathematical system and assess the consequences of the impact.


As the Tesla worker explains in the video, industry standard crash tests were used as the basis, but for the firm led by Musk “those crash tests are like grains of sand on a beach.” For them, reality is infinitely more complex, since each shock is different and multiple variables intervene to take into account.

Now, Tesla has decided that to design its cars it prefers to take advantage of the real-world data provided by the sensors of its more than a million vehicles on the road, some of which are inevitably involved in accidents. Several even are being investigated by NHTSASince it appears that the Autopilot is not always able to recognize emergency vehicles.


As stated by the personnel in charge of the new type of safety tests in the “Crash Lab” with the data collected by the multiple sensors that their cars carry, now they can “detect in 10 milliseconds what kind of shock it is”And make the airbag react accordingly.

Thus, when the crash occurs, the Tesla car will be able to know the exact position of the seat and the steering wheel, regardless of how the driver has adjusted them, and deploy the airbags for optimal safety of its occupants.

After many simulations, they tested it for the first time with a pickup that crashed into a Model Y. The automaker described the results as “a world first” and said the test was a success.

These tests are added to those that the brand is carrying out to improve its “Tesla Glass”, A double pane glass with an acoustic damping layer in the center, which aims to fulfill a double function: to be safe in the event of an accident and to protect the occupants from UV rays and noise.

Some tests that could help the development of your front windshield, with the aim that it acts as lens for your autopilot camera frontal.
