The Japanese government has started a “flying car” project, bringing together more than a dozen companies, including All Nippon Airways, electronics company NEC, Toyota-backed startup Cartivator and Uber, the ride-hailing service. Toyota and its group companies have also invested 42.5 million yen (375,000) in a Japanese startup, Cartivator, that is working on a flying car. (AP Photo/Koji Ueda, File)

Electric drones booked through smartphones pick people up from office rooftops, shortening travel time by hours, reducing the need for parking and clearing smog from the air.

This vision of the future is driving the Japanese government’s “flying car” project. Major carrier All Nippon Airways, electronics company NEC Corp. and more than a dozen other companies and academic experts hope to have a road map ready by the year’s end.

“This is such a totally new sector Japan has a good chance for not falling behind,” said Fumiaki Ebihara, the government official in charge of the project.

Nobody believes people are going to be zipping around in flying cars any time soon. Many hurdles remain, such as battery life, the need for regulations and, of course, safety concerns. But dozens of similar projects are popping up around the world. The prototypes so far are less like traditional cars and more like drones big enough to hold people.

A flying car is defined as an aircraft that’s electric, or hybrid electric, with driverless capabilities, that can land and takeoff vertically.

They are often called EVtol, which stands for “electric vertical takeoff and landing” aircraft.

The flying car concepts promise to be better than helicopters, which are expensive to maintain, noisy to fly and require trained pilots, Ebihara and other proponents say.

“You may think of Back to the Future, Gundam, or Doraemon, ” Ebihara said, referring to vehicles of flight in a Hollywood film and in Japanese cartoons featuring robots.
