Well, I think it's that kind of arrogance that ends of killing thousands of bikers every year. The bicycle is not a motor vehicle but the law recognizes it as a vehicle nonetheless and therefore is illegal to ride on sidewalks where we could be a danger to pedestrians. Bicycles also have much better stopping power as well as the ability of the rider to see intersections much more clearly than those do in cars. Drivers need to be much more AWARE of their surroundings as well as being patient with bicyclists. I'd advise you try riding with traffic or getting on a bike to understand how infuriating it is when SUVs or others try to cut you off, push you off the road, hit the gas after passing you forcing you to inhale their exhaust etc. Let's not forget the jeers, the honking, and the complete lack of respect for others on the road.
