I was involved in really minor car accident. I was stopped behind a car while waiting to make a left turn from one way street on to one way street. I thought that the car in front of me already went and I was watching traffic for a break so I can go, I let go of break and hit him in the bumper at around 3mph. We both got out of the car and he said don't worry about and left. I got really lucky, I thought he will play it like he got hurt and will take my insurance and will try to collect on it.
