I noticed yesterday that my brake lights stay on are when I stop (according to the dashboard representation)
I come to a stop at junction / traffic lights, take foot off brake (level road, no roll backwards etc., for me creep is OFF), car sits still, but brake lights remain on until I pull away.
I wonder if that is a nuisance for the person behind me? - never really thought about it before, but I have seen people say "I wish people in front of me would not stay stood on their brakes when we stop in line"
Interesting, in the States it seems that it is the norm that everyone stands on their brakes as they're stopped in lines. Probably why you're seeing the brake lights on with the "Hold" function.
I've seen it where there were near accidents because someone didn't have their brake lights on while waiting at a light. The person coming from behind may have thought the car was going to go or just didn't notice them, since the lights were off.
I'm guessing that some of it comes from the fact that a larger proportion of cars in Europe are manual transmissions, opposite that in the States.
