The flying car MEME has always been absurd so long as robot control is impossible. We are now getting there. That still leaves the problem of failsafes.
Failure modes turn you into a brick rapidly converging on the ground. Normal automobile failure turns you into a brick converging on the side of the road. That turns out to be survivable in most cases.
We will still have auto drones able to take passengers from point A to point B while using elevation and 3D space.
Another alternative is the craft above that i do believe is feasible. It is a gravity ship unable to generate an excess in altitude except to jump over obstacles with AI support. Better yet it can apply real brakes as well far better than physical wheels. The internal gravity disc cuts into the ground and grabs it allowing braking to be applied. That craft does not need those jet engines as it makes it risky to control..
On a wing and a prayer
As part of our ongoing obsession with rethinking cities, we’re bringing you a six-week bonus series on the future of mobility. It will land in your inbox on Mondays, while the regular edition will touch down on Wednesday as usual. This is Week 3!
For as long as there have been planes and automobiles, people have been hoping to hitch a ride to the future in a flying car. From the Jetsons to Peter Thiel, flying cars have been a shorthand for our utopian future. But for a long time, they never took off—technological struggles, regulatory issues, and money problems weighed the imaginative enterprises down. Now, inventors are trying to get cars in the sky once again, this time with the hope of reducing traffic on the ground and making transportation greener in the process. Despite ample funding from venture capitalists, the question remains: Will flying cars ever get off the ground?
Let’s go off-road.

Why it’s never really worked
Traditionally, there have been two main reasons for sending cars skyward: reducing congestion—and commute times. In theory, enabling people to drive on the road and fly just above it would double our space for traffic. In the process, it would improve ground speeds and allow flying cars, which would theoretically go 150 miles an hour (241 km/h), to shepherd suburban residents to urban centers in minutes. More recently, however, advocates have begun to envision a flying car-only future, in the hopes of repatriating the streets to pedestrians.
But hybridizing machinery has historically required a “debilitating compromise,” design consultant Peter Stevens told The Guardian. Cars and airplanes, for example, “have completely different types of engines,” John Brown, a roadable aircraft expert, told the New York Times. “Also, cars have an aerodynamic that makes them hug the ground, whereas an aircraft is designed to do just the opposite. And cars need even weight distribution on all four wheels, while an aircraft has 90 percent of its weight on the back wheels.” The two vehicles also require different skills: flying car owners must be licensed drivers and licensed pilots—this, in a world where most people can hardly handle merging on a highway.

HOW WE 🚁 NOW
Flying cars have taken many forms throughout history, but current developers are primarily focused on developing helicopters that are faster, cheaper, safer, and quieter so that they can function within cities. These machines can rise directly off the ground (or, potentially, water) without any need for a runway. Crucially, they run on battery power, not oil; another name for these vehicles is electric vertical take-off and landing, or eVTOL, aircraft. Relying on batteries should reduce the aircraft’s carbon footprint and allow them to quietly pass over the cityscape.
But some researchers remain skeptical of flying car companies’ green promises. Enabling super-commutes could lead to sprawl. Public means of travel are almost always more sustainable than private ones. And, technologically, flying cars “are going to be more energy efficient than helicopters that use a lot of fuel but they will be less energy efficient than cars because they have to lift themselves,” Ella Atkins, a professor of aerospace engineering at the University of Michigan, recently told the New York Times. The solution might just be a matter of mileage: VTOLs are more efficient the longer they fly, so reserving these machines for trips more than 60 miles (97 km) could tip the calculus in their favor.
