That is pretty bad AussieVic! The worst I've ever had are morons who yell and swear at you. I've been slapped on the bum a few times, but that was by another cyclist that I was training with and he was going my speed and I knew he just meant it as a joke. One really bad group of people though is the army. When they are passing through town on the way to do training exercises their trucks are slow and take up the whole road so they slow everyone down, and on top of that each tank or vehicle might have a guy hanging out of it yelling rude stuff at you.
