Since I often ride the same routes on my bicycle each time, the motorists I encounter seem to be expecting me. So, I try to ride in a predicable manner and use proper signals and manners.
It occurred to me that part of the problem cyclists have with motorists is that motorists may not be expecting them. Then when a motorist sees them, the motorist is not sure how the cyclist will behave. This is problem magnified by the antics of many cyclists who reason, "Well, I can perform this maneuver safely, without injuring myself, so what's the problem?" So motorists often get a picture of cyclists as erratic and unpredictable, an expectation that works against our best interest.
In the final analysis, teaching motorists how to drive along with cyclists on the road depends a great deal upon the prevalence of predicatable behaving cyclists who are all following a the same (or similar) script. Teaching motorists may be more effective on the road than in the classroom.
I believe that once a motorist finds how simple and easy it is to pass a cyclist, that motorist
is well on the way to losing his/her antagonism towards us.
