NO. I don't own a car so everywhere I go, whether it be the grocery store, library, anywhere, is by bicycle. I've gotten use to riding in traffic and learnt to respect the drivers and obey most of the laws(at least the ones that are upkept with the change in times). I don't mind riding in traffic at all and would much rather ride on the interstates than the two lane highways, even the two lane highways that have wide shoulders like here around NH. Just much safer to ride on the interstates. Been on one this summer for two miles, unplanned on, and the only thought about being there was hoping there were no cops around since it was an illegal stretch of interstate to be on with a bicycle. The road I was on dropped off onto the interstate so I got forced onto the interstate. Didn't mind it at all.

Go ride with the cars and you will get use to them. As long as you keep yourself from an environment you will never get use to dealing/interacting with the environment. Car's aren't anymore dangerous than you are. Maybe it isn't the cars that are the problem...maybe you're the problem.
