That's a bit unfair. You can actually buy a flying car today. A few companies recently got their vehicle fully certified and are doing commercial sales. It's not cheap. If you can't afford a second Ferrari don't bother.
The future is already here, it's just not evenly distributed.
And the modern replacement for the helicopter is the eVTOL. That one is also often called a flying car, although they're not street legal. As far as I know nobody died in an eVTOL yet.
Right but none are what the past thought of. None of these are cars or street legal really in any way.
Also it's cheating to say no one has died in them if nobody is really flying around them. There have been crashes but like a really limited sample size.
This one is street legal and flight certified: https://www.pal-v.com. The others are still doing certification. But yeah, it's not really what people thought the future was going to be. It never is. Retrofuturism exists for a reason.
https://www.pal-v.com/ is one for example. Certified for road and air. You need a pilot license and a driving license. And it needs a short runway to take off or land. €499,000 excluding tax.
