As has already been said, watch your speed. Plenty of police/State Troopers parked on the side of highways, waiting. Its the easiest place i have ever driven. Rarely get traffic backing up. Its usual for huge storms to happen, usually in the late afternoon. The highways can become horrendous, I witnessed quite a few crashes comming off the skyway bridge into Tampa. I also watched a guy, swerve three lanes, swerve back three lanes, do a 360 spin and then just carried on driving like it was nothing. On the highways you can pass on both sides because, even across the Atlantic they have middle lane drivers. These rules also apply for trucks. It can be pretty daunting if you have two 18 wheelers smashing past either side of you.
