- Tesla Vision can help airbags deploy up to 70 milliseconds earlier in unavoidable crashes.
- Impact sensors still make the final call on airbag deployment; cameras alone won’t deploy them.
- This feature will roll out to existing vehicles through an over-the-air software update.
Tesla vehicles use their cameras for everything from advanced driver assistance and automated driving to replacing parking sensors, and now the manufacturer has found one more use for them. As part of a recent update, the camera array will help the vehicle prepare for a crash and even deploy the airbags sooner when it detects that a collision can’t be avoided.
The automaker recently released a video explaining how this works and says that Teslas can now deploy their airbags up to 70 milliseconds earlier, which could make a difference in the event of a severe crash. Tesla contrasts this novel use of cameras with the limitations of accelerometer-based sensors, which must wait until a crash has started before determining whether and how much to inflate the airbags.
In a Tesla, the cameras can now identify the type of impact, estimate when contact will occur, and judge its likely severity before the physical crash sensors even begin measuring it. This gives the car’s restraint systems, like the seatbelt pretensioners, time to prime and prepare for impact, boosting occupant safety.
Inflating the airbags sooner, even by a fraction of a second, is important because, even though when you watch a crash test in real time, you see them popping up instantly, they actually take time to inflate. In some instances, they don’t fill up quickly enough to provide maximum protection, which is what Tesla is trying to prevent.
Even with this system implemented, Teslas still rely on traditional impact sensors to make the final decision whether to deploy the airbags, but they now have an extra layer of control from the cameras. Tesla vehicles are already among the safest on the road with very high ratings from various automotive safety organizations.
Tesla says the feature will reach existing vehicles through a software update, but it has not specified in the video which models or software versions are included. Browsing over-the-air update logs from the last few months, I didn’t find any specific mentions of airbags (other than a “Frontal Airbag System Enhancement” from a September, 2025 update).
