I don't live near FL, but from what I see in MD (and PA and DE), I'm biased more to the views CommuterRun and CB HI. To me, the FL law looks like bicyclists still have to justify leaving the bike lanes; the only difference is that the list of unsafe conditions is a little more explicit (if it is considered relevant) but bicyclists need to justify riding outside door zone lanes or lanes to the right of right turn arrows (standard MD and PA design).

I keep reading that MD has repealed the mandatory shoulder rules, but from the details I read, it looks like it is only repealed if it is exceptionally unsafe and stupid to ride on the shoulder, where theoretical exceptions already existed before. (But not frequetnly allowed, look up Leymeister.) Similarly, MD recently passed a 3' law, but the final version has so many exceptions that it basically says if the road is too narrow, the motorist has the right to pass anyways instead of waiting until it is safe.

MD also has the most egregious local restrictions (no exception to mandatory bike lane use for bicycling at the speed of traffic )- if we allow bicyclists to take the lane they won't use door zone lanes when cars in rush hour traffic are are going at slow bicycle speeed.

The single file in NHconflated with a requirement to ride as far right as possible (not practicable), and applied to bicyclists that won't let motorists pass in 10' lanes in 20mph congested traffic. Keri's FL site has a video of a motorist with an open lane to pass shouting at a policeman that bicyclists are required to ride single file when they already are, just not in the gutter of a narrow lane

As long as the bike lanes are designed and evaluated by motorists (planners, police, judges), I don't see any enforcement of the minimal protections these laws purport to give bicyclists.
