The speed of the airbag is remarkable. It's fully deployed and waiting moments after impact (see 54s, easier to see with 0.25 playback speed). Perhaps a rare example of an explosion that saves lives.
- unwind 4y agoYes, it's really cool to see. I imagine it's really scary to experience in a less dramatic situation, i.e. when you're not crashing but still having the bag inflate while in the driver's seat (hit when standing still etc). This article [1] has good technical details about construction and so on, two facts: the bag moves at around 200 mpg (322 km/h) when inflating, and it's all done in 1/25:th of a second, i.e. 40 ms.

- sidewndr46 4y agoI watched a video a while back where a BMW driver just drives off a cliff (and survives). He had an in-car camera. Apparently BMWs sense free-fall and just go ahead and deploy the airbags. They were fully inflated seconds before he hit the ground, probably saving his life. I thought this was a pretty interesting safety feature.
