We have "flying cars": they are called airplanes and helicopters. The latest trend is towards a hybrid vehicle that combines the Vertical Takeoff and Landing (VTOL) capabilities of a helicopter with the forward speed and efficiency of an airplane. Battery driven electric motors add another dimension to these designs as does autonomous operation. The SkyDrive flying taxi seems to be an electric quadcopter [1] with coaxial rotors [2]. I'm assuming that the key advantage over a traditional helicopter is a smaller footprint due to the quadcopter configuration. Perhaps we are conflating two innovations: functional electric passenger quadcopter and the infrastructure for flying taxi services.
