It's so shocking to me every time I visit, when I'm driving. Absolutely no fucking one keeps the correct lane based on speed and route. It's China - level bad driving all around.

Contrary to myth though, Southern Florida is not worse than say New Jersey or Los Angeles or Chicago, to mention the three places other than Miami I drive most often when I'm there (mostly NJ). If I had to pick one where drivers are marginally more terrible it would in fact be Los Angeles.

Also contrary to myth I've never found Manhattan to be daunting, but I'm from a Mediterranean capital so there's that.
