The demos for the future tech are fun for sure, but the Cybertruck and Tesla Semi started this exact same way. The Cybertruck arrived incredibly late, wildly missing even conservative estimates of it's capabilities, and at damn near double the price they teased, AND the units that have shipped have been a fucking mess, to such a degree where Tesla seemingly can't even give them away. And the Tesla Semi has still failed to materialize at all.
So yeah it's a bit of a joke to me to have them hocking a flying car, when their pickup truck can't even drive up a steep unpaved hill, that even my old clapped out F-150 on it's SUV tires would manage just fine.
Edit: and to clarify, I know that it can do that, because I helped a friend move some exercise equipment he bought at auction back to his house, and he has an open-back basement. We backed my truck with trailer down the hill, unloaded it through his basement patio door, and the truck then had to climb back up to the road. And I was a little nervous to be honest, but it did do that, despite as I said having SUV tires on 22-inch rims LOL
