They aim to be much cheaper to run. Helicopters are mechanically complex so require a lot of maintenance, and have multiple single points of failure so you can’t skip the maintenance, and are demanding to learn to fly. The hourly rate of a helicopter is high. Electric motors are simple and reliable and all these companies use multiples so have some redundancy. Multi-rotors require computer control for stability. With…
Sure, they're trying to make it cheaper. But all of the eVTOL designs I've seen can't autorotate, making them much less safe (contrary to your implication about redundancy). Everything I've seen about this space is people with big checks trying to cut corners to enter a new market, and it seems ripe to fail much like the 737-MAX. https://www.forbes.com/sites/jeremybogaisky/2019/12/01/insid...

#22There are a lot of companies working on "flying taxis". All of those seem to have a large footprint with lots of rotors, meaning they will need dedicated landing/take off zones. This seems to limit their usability a lot, turning them more into a short range point to point helicopter service. Not to mention the noise pollution. Those things are all loud. Combine that with limited speed and range, and I just don't see…
From what I gather most companies in the space plan to land and take off from rooftops. That leaves a lot more options for stations and edges connecting them leading to a denser network than something like a subterranean train which requires dedicated stations with tunnels in between them

What makes you think people aren't working on all the problems you think they are ignoring? I personally know at least one person working each and every one of the problems you mentioned.
FWIW I've interviewed at many of the eVTOL companies and found too much sizzle and not enough steak.
But to each his own. Ultimately it's just my opinion. Reality will assert itself regardless of what I think.

#24One only see a few helicopters at time in typical city skyline. I wonder what happen if there are just 100 of them on the air at the same time.

There's actually examples of this in the world now. In São Paulo, the rich take helicopters between buildings [1]. [1] https://www.theguardian.com/world/2008/jun/20/brazil

The people with the money for these have the political power to force others to deal with the noise. Already, helicopters have remarkably few restrictions. If you can afford one, you can fly it almost anywhere you want.

#28More glorified complexity. I would pay more to ride in something with highly reliable simple hardware.

#29This is pretty much everything you need to know about Toyota - everything you need to know about corporate Japan - wrapped up neatly in one anecdote. Toyota can’t make a plug-in electric car to save themselves but for white elephants like flying cars and smart cities they are all in.

#30This makes a lot of sense for Toyota. Their hydrogen fuel cells probably make a lot more sense in this context.
