Mark, I take on board points 2 & 3 but can't understand point 1. It is difficult to get people to walk when the green man and audio appear without them first watching that vehicle slow to an stop. I cannot believe people would 'press and go'. If a delay was introduced, are they not just as likely to walk as soon as they see the vehicle amber under the same argument?
