A guy on a bike, bent my Dad's wing mirror once. It was on London Bridge in stationary traffic. He bent it in so he could get passed. My Dad turned off his engine.......well he wasn't going anywhere.........he walked up behind the guy on the bike, he had had to stop by then. Tapped him on the shoulder and ask him to go on to the pavement as he wanted to speak to him about his actions............. the guy on the bike did as he asked.
My dad asked him to take off his helmet n get off his bike, the guy refused to do either...............lets just say he ended up on his side with his bike on top of him!! And the people in the cars around him applauding my Dad!
Just becareful who you hit...........It could back fire!!
You will just have to learn to ride defensively..............LIKE THE REST OF US!
