Letting 5 cars pile up behind you can happen in the course of a few seconds to several minutes. Those are two totally different circumstances. The former is unlikely to be a major impediment, while the latter probably is. On some roads, if you try to pull over to the side every time more than 1-2 cars are behind you, you'd never get to your destination. I'd say it's reasonable enough to move over to the side ever 2-3 blocks.
Most cars are blocked by other cars on the road and you don't see cars honking at other cars nearly as often as it happens to bicyclists (except maybe in NYC... hehe)
Also, most of the time the substandard width lane issue is only a factor within cities. Cars shouldn't really be traveling that quickly within a city, except maybe on elevated highways.
