IMHO, drivers of all ages should lose their license after the first collision in which they are determined to be at fault. They'd be issued a month long temporary permit to allow them to continue working. However, they wouldn't be able to receive their full license again until they completed a drivers ed course. Subsequent incidents could have other punishments as needed. I know it would create a huge bureaucracy, but it might help safety if people understood that driving was a privilege, not a right. It would also give us a chance to tighten up our loose education standards.
