I don't know about jail, but I find it hard to believe that people who have demonstrated incompetence with a motor vehicle, fatal incompetence, are allowed to drive. Anyway, there really is only one long term solution: exclusive roads for non-pedestrian, non-motor vehicles. We should aim to solve these problems by making it hard for people to have them. I don't think a punishment deterrent really works in situations like these. Most people drive in a switched off mode, and they aren't going to change.
