I rarely see cyclists doing that. And when I cycle and there's an unobstructed bike lane, I'd certainly rather use it.

Usually, when I see a cyclist in the road when there's a bike lane, it's because there's a car blocking the bike lane. I mean, they can't do anything about that.

I can give a laundry list of obnoxious things that I've seen cyclists do (e.g. ignoring red lights, cycling the wrong direction on the road, not signaling, trying to squeeze by cars that are turning and have already merged to the right), but sitting in the road for no reason is not one I've seen.
