The life-size electric drones known as eVTOLs have produced more hype than flight time over the last half decade. But many leaders, like Joby, Archer, and Vertical Aerospace, are now moving into more advanced testing phases with certification not far off. Some one-seat eVTOL makers, like Pivotal, have already started delivering their electric aircraft.

At the same time, with far less publicity and investment, dual-purpose, street-legal flying cars have started to take off. Creators like Klein Vision have already gained certification for the AirCar in its home country of Slovakia, while in California, Samson Sky has made structural modifications to its Switchblade flying car in preparation for commercial sales.

While both aircraft types have been called "flying cars," they have very different origins and ultimately missions. A concept that has emerged in the last decade, electric vertical takeoff and landing craft (eVTOL) offer space-age looks and technology, along with eco-friendly electric propulsion. The larger, five-seaters are largely going to be used as executive transport and air taxis.

By contrast, flying cars that can also travel by road have been an idea for more than a century, with one that went into limited production in 1937, but never really gained commercial success. These hybrid forms of transportation tantalize with the promise of both in-air and on-ground transportation all in one package.

To get a sense of how the two classes of vehicles compare, we lined up two that are aimed at individual users and promise delivery in the relatively near future. The Klein Vision AirCar or Doroni HX-1. Which would you choose?
