Blue haired ladies driving "land yachts" were a big factor in my giving up my bikes several years ago. Coupled with slowing reflexes, it was just getting too dangerous for daily trips to work, since the odds were growing against me. There are bad drivers who don't even seem to see emergency vehicles with lights flashing because they're in that "cocoon" envrioment of the personal automobile. On the other hand, my experience is that quite a few bike riders 1) find it impossible to drive within the limits; 2) flaunt the ability to "slice & dice" in traffic; and 3) the younger riders tend to believe that Suzuki, Honda, and Kawasaki equipped their bikes with force fields from "Star Trek" so that they don't have to worry.
