The flying car is one of the most enduring anticipations about future transportation (here depicted as a helicopter-like vehicle) and a pervasive theme in science fiction (e.g. Blade Runner, Back to the Future, etc.). It essentially represents the utmost in terms of personal mobility and freedom that can be conceptualized by the general population, thus its enduring popularity. Even if technically feasible, the diffusion of flying cars to the general public remains quite unlikely (there is a niche potential) mainly because their energy consumption per passenger-km would be prohibitive in addition to create complex navigation and air traffic management situations. Without close to complete automation, operating a vehicle in a three-dimensional environment remains hazardous to the bulk of the population.
