Electric air taxis would be great for commuters. You would have to streamline check-in and security though. People will ditch their cars for a faster trip time.

Consider this scenario for a 20 mile commute: 1) Bike or walk one mile to local air strip ( a converted road) 2) 18 mile electric flight to destination town. 3) Bike or walk one mile to office from landing strip.

Takeoff and landing must be silent and fast. See http://electrictakeoff.com for an example.
