I'm a guy, so I can only speak for myself.

Most people think I'm crazy for riding my bike on the road. I think I know why.

When I'm driving, I get harrassed, too. Minor, perhaps, but people pull @&*# all the time--cut off, tailgated, buzzed, etc. It's bad enough in a car--no wonder nobody wants to ride a bike out there on the road!

But the strange thing I can't seem to get anyone to believe is that I get much less harrassment on my bike than I do driving my car. Much less.

But that is not to say it's not a very important issue. Being on a bike makes you feel very vulnerable.
