I suspect that the different road behaviours of Tallahassee (or even Nottingham) and London render comparisons difficult. Although there are cyclists who ride with neither consideration for their fellow road users nor seemingly even of their own lives, they are a minority. Most of us interpret the law flexibly given the flexible status of a bike.

For instance, we all use a version of the perfectly sensible US law of the (right) left hand turn rule. At a T junction I will filter into traffic as turning right as I'm not remotely interfering with it, even tho' I'm supposed to stop with the cars that would.

I ride very defensively, traffic in the SE of England scares the bejeezus out of me because they don't care and so you plot the path that keeps you out of their way as much as possible. And if that means jumping lights to get away from the invariable race car start off lights, then so be it.
