In my experience living just north of Tampa, it takes a LOT to get pulled over from speeding. The County cops have their work cut out with all the meth heads near the gulf coast, to be bothered with speeders. You know how everyone says about cops "dont you have anything better to do??", down here they actually do. You have to try REALLY hard to get pulled over from speeding. Now the Florida state highway patrol, thats a different story. Be nice on the highways and you will be fine.
Gas is cheaper than most places around the country. I came from the midwest and its still cheaper here than up north. Car insurance is 2x the cost though because Florida is a not at fault state and you will find the world's worst drivers here. Mostly the diks from NY and NJ that come here thinking they own the roads.
Aside from that, this is a nice place to be a car guy. You can drive them year 'round and there is plenty to do and see while enjoying your car.
