Increasing number of cars on the roads worldwide forces large cities to take active steps in search of alternative travel methods, such as passenger drones. There are quite a few companies, who presented prototypes of a passenger drone, following my personal top 5 most promising passenger drone providers.
Ehang184
Ehang184 is a one-person passenger drone. It was originally announced to start flights in July 2017 in Dubai. Even though that deadline was over-optimistic, now the Company presents a new prototype of a 2-seat drone, that is being reviewed by regulators. According to company CEO's statement, the passenger drone was built with full redundancy in its systems,  100% green technology and is powered by electricity.

Volocopter
Intel made a very bold keynote at CES 2018 presenting its concept of passenger drone in collaboration with Volocopter (backed by Daimler) presenting an actual Volocopter VC200 flying across the stage.

Volocopter VC200 flying across the stage is a two-seater 18-rotor passenger drone, that can operate both: autonomously and by a pilot. The current fly range is at 30 minutes or 17 miles. Volocopter VC200 already obtained flying permit in Germany.

Lilium Jet
Lilium Jet is a German company, that accomplished its first flight in Munich back in April 2017. This electric passenger drone takes off vertically, very much like a helicopter, but features an ability of a "jet-like" horizontal flight. This unique combination unlocks an ability to travel at a speed of up to 300 km/h and have a flight range of 300 kilometers.
