During a race a racecar sails into the pit, the pit crew jumps down and uses compressed air to unbolt the lug nuts as rapidly as they can.

On racing road bikes there are levers that allow bicycle wheels to be quickly removed from the frame.

Why not create a similar lever system for cars. It might need to be beefier, but shouldn’t the same mechanical principles hold?
