On the busy Franeker ring road the car in front of you suddenly brakes hard. You do not react straight away. Your car has an autonomous emergency braking system. What does that system do?
It only warns you; you then have to do the braking yourself
It warns you first and only brakes by itself if you do not intervene
It brakes hard by itself straight away, without warning you first
Explanation
False — You stop at the warning. After the signal the emergency braking system intervenes itself: if you do not react, the car brakes hard automatically (Book p.219).
