$TSLA: My car can fly—can yours? The Roadster applies rocket propulsion principles to a sports car, integrating $SPCX rocket technology that uses high-pressure gas jets to generate thrust, briefly lifting the vehicle off the ground to achieve short bursts of flight and mid-air flips. What’s the point? It’s far more about showmanship than practical utility—similar to foldable screens. Unless it can achieve sustained flight and let you simply fly over traffic jams, it’s mostly spectacle. Still, it’s a small step forward for automobiles—must cars really rely on wheels? In the future, autonomous aerial driving might be the norm.
