My favorite is when they're freaks about safety and try to be altruistic (ex: "where's your helmet?")...

...by slowing down, driving on your shoulder, and screaming at you.

Had someone do this at an exit to the freeway once. I had to stop and walk across.

I don't think people doing that are trying to be altruistic. They're trying to engage in harassment.
