Plenty of companies are working on manned flying drones and taxis these days. Not surprisingly, these flying machines have to go through various tests. This video shows a Volocopter test flight. It lets you bypass congested streets by flying in lower airspace in cities. It has 18 rotors and seats 2 people.
The VoloCity air taxi has been in over 2000 test flights. It has multiple redundancies, with the rotors, electric motors, and batteries all have at least two replacements. The above video shows a Volocopter test flight at the Palace of Versailles.
