...I don't know why you think that a majority of drivers respect bike lanes. They don't. Nearly every driver has parked a car in a bike lane at some point. At least in the US it's uncontroversial - the bike lanes tend to be so poorly designed and thought out that it's much easier for cars to use them than cyclists.
I think majority respect them, because I drive bike in a city that is not exactly friendly to that. The situation is, some people break into them regularly, most dont.
