I tend to agree with this. Rather than flying cars with very limited flying range, I think it might be better to put the effort into leveraging battery and electric motor technology to add VTOL or near-VTOL capabilities to current fixed-wing GA aircraft. The result would be airplanes that are likely to be safer with the ability to operate out of very small airports but still used for longer distance travel. Potentially they could also be made drivable or at least trailerable with folding wings.
