The future of air mobility is here. Introducing the new #EmbraerX eVTOL concept, an electric vertical take off and landing vehicle that will revolutionize the world as we know it. You helped us design it. Now help us to name it: https://t.co/ZGXU5Xt6VX #nameyourevtol #UberElevate pic.twitter.com/GHCsARVwEm

Everyone is coming out with an "urban" transport but I have yet to see the demand...or even see the rationale.  We're gonna replace jammed walkways with jammed airspace in dense urban areas?  If it's possible (and if it is it's a ways off) then now is not the time.

Is this a case of building it and they'll come or just wasteful spending on an idea that will never be?

I'm leaning toward wasteful spending.
