If an inventor made a compressed air car, even a go cart ( improving range by larger weight of tank vs lighter weight of vehicle) could they move it far enough to get from one gas station air pump to the next

if they didn't, how about air pumps at tire stores, Firestone shops, motorcycle shops, etc?

Compressed CO2, N2, also would work if you could figure out where you might stop by and get some either cheap, or free.

So, I suppose travel in a city would be possible, until the shops get annoyed at seeing someone mooching off their compressed air, (costs of running compressors, etc) but would a person be able to travel between towns to get to the next supply of compressed air?

Also, what about supplementing the air from those air pumps, with a couple foot pedal pumps that are being pressed on constantly while in motion? Using hand grips like a motorcycle would free up the feet for pumping a bike air pump.

Adding a couple pumps that are operated by every bump you go over would also assist in supplementing the compressed air supply, something that quickly flips from motor spinning the drive shaft to neutral, and the engine stopping, to make the most use of steep hills.

Just a thought. Maybe even a sail to assist in pushing, or pulling the cart along, or a kite in areas there are no power lines and telephone poles or trees
