Not really. Some of the worst driving around cyclists that I've witnessed has come from members of my family (with me in the car) in places with lots of cyclists (Philadelphia and Ocean City, NJ). Close passing, intolerance of having to slow down, etc. Some people are, and always will be, overly cautious of cyclists because they don't see them often. Some people, are and always will be, a-holes around cyclists even though they are surrounded by them because they are simply jerks (on the road at least).
