Of course we want. But to see why, you can't imagine it as a car, like everybody insist. It's will be a vehicle, but not a plane, a drone or a car. They will not compete with these.
We definitely need for example a faster way to transport rich people than cars, but cheaper than planes in short distances.
We definitely need a better way to transport patients between hospitals than ambulances and helicopters.
We need to see the future here, not the past (the outdated idea of 'flying cars')
