Race cars suck

Really. Formula One Grand Prix cars and other racers use aerodynamic down force to suck the car down to increase tire traction and to keep the car from literally flying.

The suction created under the race cars is so strong that manhole covers have to be welded down when the cars take to street circuits such as Monaco and Long Beach.



F1 cars produce more down force than they weight at speeds over 80 mph, so the car could actually stick to an inverted road!
