Most cyclists are aware of this phenomenon. This is the urge many/most motorists have that practically forces them to get ahead of any cyclist in front of them ASAP. Blind curves, hills, stop signs just ahead, oncoming traffic and more… matters little many times. My theory is that cyclist behavior at least partially promotes this mentality. Here’s why… In practically every area I’ve ridden in or been to, almost all cyclists ride as far out of the way as possible. Curb or gutter hugging, riding in door zones or on scrappy unsafe shoulders and sidewalks, etc., seems to be the rule. Stay out of the way of the large and powerful motor vehicles by any means possible to ensure safety, seems to be the thought process behind this behavior. It can seem wise on the surface, but it can also encourage overtaking when it would not be safe to do so. When motorists consistently observe this cyclist behavior, it is what they become accustomed to. Cyclists always stay, or move out of their way. Having to slow and wait behind a cyclist for even a few seconds can really can be quite foreign to them. Maybe it’s different in your area, but this is what I see. I question if this common “Staying Out of the Way” tactic doesn’t promote the common “Motorist Must Pass Cyclist” mentality. Maybe if more cyclists were a little more assertive (especially in narrow lanes and other situations that call for it) it would help dispel the Motorist Must Pass mentality, and lead to safer, more comfortable road interactions for everyone.
