I grew up in Florida. The population is now 4x what it was in the 1970's, but the roads aren't much more extensive than then. Traffic down there is on par with Long Island, NY! (south of the I-4 corridor) If you are going to move there, I think the FL panhandle is still somewhat liveable, but you might want to be inland quite a ways, to have some protection from the hurricanes :) Definitely visit down there before you decide to move there.
