Members of Cartivator carry propellers of the test model flying car in Toyota, central Japan, Saturday, June 3, 2017. Cartivator Resource Management, in which Toyota invested 42.5 million yen ($386,000), showed reporters Saturday a test flight of a concoction of aluminum framing and propellers. It took off several times, hovering at eye level for a few seconds, before falling to the ground.

It would be a truly Olympic feat.

A start-up backed by Japanese automaker Toyota revealed a rudimentary prototype of a flying car, aiming to whisk a driver through the air to light the Olympic torch in Tokyo in summer 2020.
