I'm wondering along the same lines, at what speed does the car decide to deploy airbags, and at what speed to automatically brake? And how hard is the braking?

I'm wondering along the same lines, at what speed does the car decide to deploy airbags, and at what speed to automatically brake? And how hard is the braking? I'd imagine it would be pretty hard braking to prevent the car from hitting something. But one would hope the car wouldn't be going fast enough to lose control.
