Glad you are okay - and I sure hope he pays for your bike - sounds like the driver is trying to be accountable for his actions (so many people are not these days).

Good for you trying to memorize the license number! You never know if they are going to stop or not. I got hit by a young girl a few years ago and she was not going to stop but another motorist that saw the accident drove up beside her and that made her feel like she had to stop. It was a good thing cause i ended up sitting backwards from her on the ground and had not gotten up yet from the ground.
