i think elon is building the short burst flying car powered by compressed air for mars and not for earth. since it's not practical to build roads there, we might as well just bypass them. also much easier to operate this tech on mars compared to earth given the difference in gravity. he has solar panels, optimus and now a flying vehicle and starship to take us there. no one knows how many times earth and civilization have restarted due to external factors like asteroids and we don't know when the next event is gonna happen. i think this is our only chance to protect humanity for now. hope ai helps us expedite the process.
