Flying taxis are going to become very common in the future. A bunch of companies are working to perfect them. Take the EHang VT-30 for instance: it is a long-range passenger grade autonomous aerial vehicle with a range of 300km and flight time of 100 minutes.
This aerial vehicle can carry two passengers from one city to another. According to EHang, the VT-30 has gone through vertical take-off and landing, power system and other tests. You can find out more about it here.
