Driving a car is also dangerous, more people are killed or seriously injured in motor vehicles each year than on bikes. Sure, there are far more motor vehicles on the road, but why add to the pool and become a statistic? Glad you are ok, though! My brother had a bad off a year or so back when if I recall someone doored him and I do worry about him, but that is kinda my job. I would never suggest he give up biking just because of an accident, and it has made him a more careful traveller.
