Yikes! Easy with the shouting. I always use the brake pedal, for extra control. Although it has to be said that the emergency braking system in my car once responded fractionally quicker than I did, and the brake pedal was already depressed when I got to it. Even when the car is slowing itself ‘cos I’m decelerating e.g. for a junction, my foot is hovering over the pedal to apply more pressure when it’s needed. The question was whether the lights come on, nobody mentioned relying on the system for normal braking.
Yes I was also confused by where that reply came from 🙂
