Anyway, I don't see it feasible to buy one of these, spend 500,000+ USD to occasionally travel somewhere on your vacation? That is the same reason why we did not buy a helicopter (mainly because we would have it parked throughout the year and also, the energy consumption makes it unviable for daily use).

Until a car is created that can take off from the streets and has low energy consumption, it cannot be said that we have a "flying car", at the moment we only have a "car-helicopter hybrid".
