I commute about 100 miles every day. While I've had a couple bad experiences on a bike, I've had far more in a car just doing that drive. Yes, people will shout at you in a car out their car window, too.
At this point, PO'd crazy drivers simply don't faze me in any way while I'm operating any vehicle. I've simply come to expect it as a part of a system where anyone with a pulse is allowed to drive.
