when i drive any highway, i stay in the left as much as i can. when your in the left lane, you have the car in front and the car to the right to worry about. when your in the right lane, you got the car in front of you, the right of you (entering the highway) and the left of you. three and four lane highways, i stay to the left and drive the speed people are in front of me are doing. you just have to watch for the exit left only lanes. orlando and jacksonville have left exits but if you what the signs over the highway, it shows you what lane will break away and what lanes remain going straight. there are no suprises like we have here in the north, its well marked. just dont drive in the left lane going 55 when eveyone else is trying to do 75.

you may get some unfriendly waves from the locals.
