Yeo the more I think about it, the reason for those double lines has nothing to do with what is in front of you, but what might be coming in the opposite direction. If it is unsafe to be in the opposite lane, it doesn't matter whether anything is in front of you or not. He can't see you either,so all those cars that passed me were wrong to do so.

So does Florida think it is okay to moosh a cyclist, if you decide, "OOPS, not a good time to pass!"? A bicycle is shorter than a car, but I would think you need the same amount of room, IF you intend to leave the lane, not do a "close pass". It seems there is no advantage to the cyclist from this law. Of course, that may not have been the intent.
Then again, where does Florida need no passing zones? I suppose on bridges, but what other elevation is there.
