I was strolling across my local Tesco car park the other day, when a car shot backwards down one of the roadways. The driver braked sharply and then had a shouting match with someone on foot pushing a trolley. The driver then drove off at speed. What she never saw was another person pushing their trolley across the road. The driver, when reversing in anger, only looked over her left shoulder instead of both. The innocent party in all this had a very lucky escape.
Some people seem to think that in car parks the ‘rules of the road’ don’t apply and you can drive however you like. Sensible rules are sensible regardless. If you are too angry to stick to the rules then don’t drive.
