50 miles on 1 charge seems fairly inefficient to me. Especially when compared to land based electric vehicles.

Not really a fair comparison to make considering the energy required to constantly fight gravity is significantly higher with one than the other.

Additionally, one has to consider the flight path would ideally be more straight, allowing for less overall mileage per trip than a land vehicle.

I assume that explains the "for metropolitan use" bit.
