Reminiscent of Nikola's semi truck demonstration...
Or Teslas "battery swap" event which actually helped them earn them a huge amount of subsidies from the government. Watching after understanding Elons m.o. it is clearly fake or how else would they have a planned demo on stage with cameras that aren't positioned to show anything that's going on and then that tech they developed was never heard from again. They just distracted the crowd with a video of someone filling up at a gas station
