I got behind one of these dumbasses a while back coming home from my inlaws. I was about 3 cars back and everytime someone would start to pass he would swerve over a little and make the person back off. I live in the country so I waited till there was a pretty long straight away. he started that swerving business again but this time I pulled out and matted it. the other detail I forgot to mention as that I had a load of firewood in the bed and a full trailer behind me. granted my truck could pull it but I wasn't steaming away like usual. the black cloud started rolling. I smoked out 2 cars before I got to these 2 idiots on the scooter. I slowed ever so slightly so that they could get the full benefit of my 7.3 
Screw those guys.
edit: on the other topic of bicycles. there are a ton around here. I used to live down near Crabtree and I'd call it the Tour de Crabtree. Every Saturday these assholes would line up and take over the road. It's not my thing but if you want the road to be shared then try sharing it yourself. We've got a guy that helps our family do odd jobs around the house. Needless, to say he's a little rough around the edges. Well, he told me the other day he pulled up beside a bike and just rode there for like 2 miles. He wasn't trying to run him off the road but just make a point. He said the guy finally got pissed and threw his water bottle at him
