Skeptics doubt Tesla Roadster flight: possibly an empty shell

Tesla staged Roadster jumps using 600 liters of compressed air and 10 cold-gas thrusters, removing the passenger seat. Observers and Yann LeCun suspect the car lacks a full-size battery and suction fan, calling the demo a marketing stunt rather than a real product.

• Roadster Rocket: 600 liters of compressed air and 10 cold-gas nozzles
• LeCun estimated 5–10 seconds of useful thrust, calling it impractical
• Skeptics saw no suction fan in screenshots of the underside midair
• Tesla isn't letting journalists inspect under the hood
