Yes and no.
It’s native Floridians who have those jacked up pickups “rolling coal” and can’t drive them for shit. You know, the lifted trucks that have never and will never see a drop of mud or dirt road… The lane lines aren’t even a suggestion to these assholes and I swear they add lights to be as annoying to every other driver as possible.
But you’re 110% correct about the NE transplants… good Lord… they just do whatever… right turn from the left turn lane? Sure, yep, why not? Dead stop in traffic because they’re lost? Yep… of course.
Stop lights and stop signs are a bad joke to them… speed limits? Bah… maybe don’t drive 80 in a Florida downpour? Pssh, it’s fine.
So yeah, it’s both, and lots of the complaints are towards transplants, tourists and snowbirds
