Having moved to FL, I can confirm the facts. People are not attentive to their driving, and they speed and run red lights like crazy here. They also seem to assume that because the sun is shining, the freeways can't possibly be hazardous. I suspect much of the problem can be found in our combination of punks, very senior citizens, and Michiganders.
Note to self...
If all you can see on the drivers side of an approaching vehicle is a tuft of blue hair and a pair of hands on the steering wheel, DIVE IN THE GENERAL DIRECTION OF A DITCH OR SIDEWALK.
I think your phrase "not attentive" is far too kind - willful and malicicious negligence seemed more appropriate on a few of my near misses.
