It is just compressed air, though it's an insane amount of energy stored in that form. The number that will actually have that function will be so small that it probably doesn't matter, though the emissions of car-centric transport are absolutely crazy. give me more trains!

I'm curious about the actual energy cost of the compressors tbh. How much battery range will go to car RCS thrusters?

Scott Manley estimated it at around 45kWh, so about 2/3 of a charge. Not that much energy in the grand scheme of things, but not anywhere near practical either.

Sorry, best we can do is reinvent a bus for the 50th time and make it get stuck at a red light.
