The general advice I've received from the police is that if there is not personal injury, just exchange insurance information. The individual may not have wanted to wreck his vehicle, but he did not do anything to prevent the wreck. He had ample time to react and stop, but I don't think he was even looking in my direction. I jammed on the brakes and swerved - he just kept on coming across the roadway. I was in no mood to stop and chat and make a new friend.
