I don't consider myself VC but I do ride in the lane and act as a vehicle 98% of the time while maintaing a very respectable speed. I tend to get yelled at, honked at and lectured to about how I should be riding on the sidewalk usualy at least once a day. We have next to zero bike facilities here. I say it is ineveitable depending on where you live. Our roads are narrow and shoulderless. I however don't just grin and bear it when the cars are jerks, I particulary love it. It is extremely fulfilling to yell at or tell the motorist they are number one to me. Nothing like having a jerk yell at you, then yelling back and seeing him slam on the brakes and get out of the car to cuss at me some more - thus slowing him down even more
How to stop them from doing this? Well, it ain't gonna be by done by teaching bicyclists more the rules, I say motorists need to be taught MORE manners. If teaching bicyclists the rules would change it, then they wouldn't be yelling at me all the time.

Then again I haven't owned a car in 2 years by choice, so from a motorist viewpoint, I'm the wrong one to ask.
