try to find a building rooftop in Oz that has the following properties:

1. Flat
2. Unobstructed by phone antennas, microwave relays, aircon unit
3. Big enough to terminate a Flying Car, and has a re-charge facility for said car
4. Has elevator access to roof
5. Has secure elevator that takes passengers only from lobby to roof
6. Has occupants of building willing to have this stuff happening on their roof, elevators, parking lot and lobby

OK, you have found 2 buildings in Melbourne that satisfy this requirement. Now find passengers who want to travel between these 2 buildings. Good luck.

Quadcopters with variable RPM/fixed-pitch rotors cannot be scaled up to the size needed to carry 4 or 6 pax. But CGI can do it, and make it look good.
People seem to think these things will be quiet - piddly little multiple rotors screaming their heads off, there might not be the turbine noise, but the blade noise will be considerable. Moving large amounts of air slowly is far more efficient than small amounts of air moving quickly.

Even Nostradamus had something to say about it in verse 4 Para 1: "and it shall come to pass amongst much wailing and gnashing of teeth that mankind is destined not to have a personal flying chariot, for the horses cannot be made that small."
