Hyundai has developed a solution — the E4U:
Hyundai’s egg-shaped vehicle sets itself apart by sitting atop a horizontally-spinning semisphere that is used for propulsion instead of wheels. The driver stands on a small platform and directs the vehicle by tilting it so that different sides of the semisphere contact the ground. Tech-On says this is similar to the way a helicopter works, with two rear wheels providing stability and friction to act like a helicopter’s tail rotor.
Other details are scant, but another “interesting” feature is the that the top of the vehicle can be removed and worn by the driver as an eye-catching helmet. This is dominated by a large clear visor that seems more fitting for higher speeds than the walking pace the concept is currently capable of.
Hyundai is based in South Korea, but this concept is so absurd that it would be amazing if the US government has had no role in funding it.
So, wanna see one of these MoonBatMobiles?
