“In addition to the problem of one mechanical breakdown causing death, there is also the problem of air traffic control”
The nexgen ATC system is all digital you file a flight plan electronically it comes back electronically and your FMS via ADS-B sends once per second positioning,velocity and flight vectors to the ATC system and every other aircraft with ADS-B IN which feeds the automatic traffic avoidance and all commercial aircraft will have TCAS as well which receives ADS-B and Mode S/C transponders. Licenced pilot’s will not be an issue in evtols the FAA is never going to allow unlicensed pilots in the national airspace. G airspace is very limited and has 1 mile day 3 mile night time minimums, no clouds,no IMC and 1200AGL except for Alaska and some really remote Western rural areas it’s uncontrolled airspace not incorrectly called unlicensed no NO still must hold at least PPL to fly in uncontrolled airspace. Unlicensed flight is limited to ultralight powered aircraft...ultralight aircraft have a weight limit of 254 pounds (115 kg) empty weight and a top speed limit of 55 knots (63 mph or 102 km/h) at full power in level flight. That’s it everything else requires at least a PPL then , IMC rating,then a VTOL or Helo rating then a type rating if above 12,500lbs a individual type rating for each aircraft above 12.5KLb so yeah no “flying cars” are just going to be buzzing around each one will.have to have a licensed pilot on board. Unless Congress passes a law that allows for remote pilots like large drones like a predator or.reaper must have while in national airspace via 5G or sat comm links at all times mind you.
