Got to get past the bus

A Bus is a relatively slow vehicle and as such most people, including me, do not really want to be stuck behind one. Most people will reluctantly sit behind until a safe opportunity occurs. Others choose to overtake with seamanly little regard to their own and any one else's safety. I have over the last couple of days had some scary examples of this. First, I was waiting in a queue approaching a set of traffic lights when a lady in a Range Rover started to overtake, she found to her and most people in the queue amazement that there was no where to go. She had to reverse back down the line. Luckily there was no one coming the other way or no pedestrians crossing assuming no traffic to be coming from that direction. The second had the potential to have lead to a fatal accident. I was waiting at a pedestrian crossing while a lady crossed when a car overtook me! The poor lady had to take evasive action to prevent being run over. The question is what on earth is going through these peoples minds?
