There are a lot of things you can do outside the law to deal with bullies.
Although I'm 99% sure that the officer would tell me there's not enough evidence for a case if I tried your first two suggestions, the third one is a really good idea. As long as he was actually driving instead of riding with friends, and if they didn't notice me tailing them (which I bet I could pull off). Wish I'd thought about that... thanks, now I know.
To everyone else who replied, thank you. I never really cared for group therapy sessions, but I have to say this helped a lot.
