I really like the car style because it doesn't require you to whip around the trailer every time you turn. I also like that you can keep your wheels pointed (at least as close as possible) to the direction you want to move in. The only disadvantage I can see is the robot can't turn on a dime.

Also if you do the car style, make the turning wheels powered. It will be easier, maybe the only way, to turn in the direction you want, since the surface is so slick your unpowered turning wheels may have little effect.
