Elon Musk unveiled a flying Tesla Roadster at SpaceX's McGregor, showing thruster-powered flips and rapid acceleration. The flight option is limited to an invite-only Rocket version; the Thrust variant requires $250,000 upfront. Tesla says tanks hold about 250 kg of air for ten nozzles and self-refill. Musk cautioned the Roadster is not necessarily safety-optimized and may face legal issues.
