My questions is, the claim of the makers that the down force created by some of these new super sports cars like the Saleen and the Ferrari could really hold it to the road even if the road was suddenly inverted. In effect the car would be upside down hugging the road and not fall away from the pavement. This would be due to the tremendous downforce created by the body and spoilers of the car sucking it to the road, which is more force then that of the gravitational forces pulling it away form the road.
