Are drivers supposed to stop when someone is waiting?
We cross 2 different ones on a busy road every day and not one single time has the traffic stopped unless we force them to by stepping out. I'm not brave enough to do that unless traffic is quite far away but when my husband is with me he is braver - I'm terrified he's going to get knocked over. But otherwise, at busy times we would never get across the road!
If they aren't compulsory then I don't see the point in them at all.
