As someone who has flown (in my own ultralight aircraft) I can tell you that many people aren't meant to fly. Besides the obvious (initial financial and insurance barriers, as well as maintenance costs) most commoners aren't comfortable "...slipped the surly bonds of earth,"
Add in other aircraft traffic (both manned and unmanned) and guns (pointed up at aircraft) and it's not a friendly sky. Also, most other vehicle operators an barely cope with other cars on a highway, with lanes, painted lines, and signs.
But, yes, it's a beautiful video and a beautiful dream.
We're fortunate that we can ride and enjoy our motorcycles down here on terra firma
