Yah, well, that's the problem with this technology - jet engines are air-breathing rockets, and they are NOT QUIET. This is why land near airports is cheap... The 'jet belt' of the 1960s was a jet engine backpack with two nozzles, and the shriek of high-frequency, high-decibel sound it made would induce severe hearing damage in minutes without industrial protection. A flying jet car would be even worse. This is not user friendly.On the other hand, maybe this car is using the Dean Drive.
Yes, but remember that these are ads, and even the SF needed to sell, and thus both played to an existing demographic.This isn't going to sell washing machines.
