The real front runners which are Joby Avition and Archer, Volocopter and Lilium including eHang have passed the billion dollar mark in market value but the leading flying car people are looking down on Lillium and eHamg. And Volocopter with its slow speed has no chance either. And the Archer has just been sued in the past couple of week for stealing Wisk companies trade secret and engineers. The only promising company is Joby Aviation and even they are suspicions to succeed because of probable battery endurance issues. The only design that can succeed in the next several years is one that has not hit the eyes yet. A hybrid design surely.
