Hehe, I encounter this in a more subtle way.
Sometimes, I do some night time cruising just to relax and think on the day and the days ahead of me, and I will get people who come up to me and just rev their engines. Others will just look at me until I acknowledge them (or not).
It's difficult, but I've learned to simply let it go and let them be asinine in front of everyone. I haven't had anyone harass me verbally, though.
