Toward the end of the movie, when Bo is driving toward the roadblock near the town hall, Cooter raises the back of his truck to use as a ramp. That's great except there's a rail around the front of the "ramp" about 12"-18" tall. That'd just smash the front of the car when it hits. But, the shot of the General Lee hitting the ramp shows maybe a 3" lip around the edge of the truck/ramp.
