I recommend not colliding with cars. I was riding in a bike lane the other afternoon, heading straight. Then suddenly there was a car in front of me – he had been coming from the opposite direction, and was turning in front of me to go into a side street on my side of the road.
He saw me when he was already at the bike lane, and accelerated to try and make it through in front of me. He almost made it, but even with my braking, I still ran into the side of him, towards the back of the car. I ended up in a heap in the bike lane. He stopped for a moment, then decided to drive away. Fortunately a couple of nice men stopped and checked that I was ok, and volunteered to be witnesses, and urged me to report the incident to the police (which I’ve done). Hopefully I at least dented the side of his car.
Meanwhile, I escaped with no injuries, other than feeling a bit sore for a couple of days.
