The big problem with his "stuck in traffic" scenario is how do you find the space to take off. Not to mention the legality of the whole thing.

Granted, it's a really cool demo, but he needs to admit that there is little real-world practicality.

His focus is on serving the third world. It is clear in the video you need a runway and you don't have one when stuck in traffic. Or probably the room you need to deploy the wing.

I think he should play up the fact that this takes off with half the speed Marty McFly would need to turn on his flux capacitor.

He said it could take off from a football field and clear the stanchions. It evidently needs a 300 foot unpaved field and a bit of space around it without anything exceedingly tall. That's pretty good performance, and you can get by with a lot less than a proper runway, but it can't take off from a traffic jam.

Exactly. I think the only 'practical' use would be in very rural areas (where laws may be very lax...or bendable).

Well you don't have to be stuck in traffic. Your Android or iPhone could tell you there is a major traffic jam up ahead or you might know that between x-y time, you'll hit the daily commute rush. That way you could just "take off" from your street where you know there is clear skys and low traffic.
