Same old thing. Yawn.
Heck, they can’t even make a vehicle that can drive efficiently in the city and on highways.
Even if they could make a flying car, it might not be welcome in the air or on roads.
The Segway was going to be huge, until they realized it was to fast and heavy for pedestrian paths, and two light and slow for streets. Now it is used for novelty.
The next step in people transportation will be pods that get you to a break-in-bulk hub, and fit together in larger, faster omnibi. Think shipping container.
People don’t take care of their vehicles as it presently stands - I can’t imagine a world with planes falling out of the sky routinely.
It’s bad enough seeing the carnage on our nation’s highways. Can you imagine the same stupid drivers flying over our homes too? I live not too far from an interstate highway. I would never feel safe in my home again as I would have to worry constantly about some drunken idiot falling out of the sky and landing in my bedroom.
