i said it once and i'll say it again. we need to attach paint ball guns to the handle bar or at least have it handy so you can shoot them when needed. but on a more serious not, my friend, she rides early in the morning, in a "bad" neighborhood, and cars would follow her all the way to her work, park in front of her job, and would drive off when she entered the building. and cars would follow her home too, but then she would do like 20 laps around the block, and the cars would still follow her. she carrys a very nice size knife in her back pocket to protect herself.
