Shortly after being flipped off by a New Yorker who was upset I beeped the horn at her after she's sat still when a light went green for 15 seconds or longer, I really have to stress the snowbord/traffic aspects of Florida; and the traffic is WAY worse in Miami than it is here(Tampa/St Pete area), and this area has gotten SIGNIFICANTLY more annoying than usual just in the last two weeks.
I mentioned traffic problems and one of the causes for it above. Along with this is the annoying need of many south Florida drivers to hit the horns to let people know that they don't like the fact that they have been waiting in traffic interminably. I have many times been in a situations in which I am perhaps the 5th or 6th car back in line, waiting for a light to change. The light changes, and the first car in line promptly starts to go, followed promptly by the second car. The rest of the line has not had a chance to move yet. At about that time, some imbecile about 3 cars behind me will hit the horn. I am not sure what it accomplishes, since everyone else has been waiting for a long time and is eager to go as soon as the car in front of them moves. It happens a lot. I have driven in a lot of states, and I have never seen it like this anywhere else.
