my home air compresser uses alot of electricity just to get up to 100 psi, air cars run off a tank that is 10,000 psi simaler to what a scuba tank is, or compressed welding gas, only much much larger! have you ever noticed trucks that deilver compressed welding gasses have warning lables all over them? even for innert gasses, if you puncure a tank like that it is going to do alot of damage, I think myth busters did something with a cinder block wall and a tank of compressed Co2, that is why every 5 years I am required to have my Co2 tank leak tested.
air cars also have the same kind of problems electric cars do in cold weather, as the radiator in an air car is helping to keep the engine warm (reducing presure takes energy/heat with it, it gets cold) so on humid days your radiator is a block of ice, in cold weather your range is decreased a great deal.
