Yep .. quite a lot of them, for substantial periods of time.
Contrary to expectations it didn't seem to affect the tubes or tyres, shorten lifespans, etc.
FWiW I grew up in fairly remote parts of the world and we repaired pretty much everything as much as possible with what we had - aircraft, helicopters, radios, etc.
My first thought, to be honest, was "Why not just grab a spare spark plug from the boot?"
I'm guessing not so many people stock spares when driving so much anymore.
You can also replace a blown out tyre with a hard wood skid if pressed, weld up broken steel with car batteries, stuff tyres with grasses, etc.
You'd inflate your tires with a gasoline and air mix?
