Elon Musk got laughed at explaining flying cars in 2018. 🧠

Joe Rogan is laughing because it sounded absurd. September 2018, and Musk is describing a car with rocket thrusters bolted to it. Rogan asks what they'll burn. Nothing, Musk says. Ultra high pressure compressed air. Cold gas thrusters, pumped up to about 10,000 psi. Then Rogan asks how fast, and Musk says they could make it fly. On October 15 this year, at SpaceX's rocket test site in McGregor, Texas, the Roadster climbed a curved wall, kicked itself over a line of parked Teslas at around 7 metres, and flipped beside a tower before landing on its wheels. The system is cold gas thrusters fed by a composite pressure vessel. Reported storage pressure, up to 10,000 psi. The same number he gave Rogan eight years ago. What he got wrong was the calendar. The Roadster was first shown in 2017 with production promised for 2020. The new target is 2028. He described the machine correctly and missed the date by eight years. That's usually how it goes with him. 🔎 We fact-checked 10 expert AI predictions so you know whose calls are worth listening to. It's free in channel bio.
