A full ground-effect vehicle.We can't do that.The full-length skirts must skim very close to ,if not actually touching the ground,for the entire length of the vehicle.Low base pressure from the wake can communicate forward,underneath the vehicle,via the tunnel,effectively vacuuming the vehicle to the ground.JCB is at speeds where "flight" must be considered,especially if the car loses traction and begins to yaw.You end up like Ed Tradup in "Danny Boy",off the salt,and in the air.Ground-effects downforce helps avoid wheelspin and fish-tailing,to maintain straight down course attitude.If they still manage to get sideways,the drag chutes are the only thing left to the driver to keep the car straight and on the ground.Spooky!
