We all know about the crazies out there, and are usually semi protected by our cars. Add in the ignorance of the public of how fast a bike moves, how fast it stops, and the fact that cyclists have equal right to the road as a car, and it can get really dicey.
For a while I was logging 10,000 miles /year and was blessed not to have made contact with a car since about 1975. I can not however even cout all of the close calls.
Once again, I'm glad you're OK
