I doubt the likes of Hyundai are looking to sell their things “in the hundreds to thousands” range.
It’d a a big change in air traffic and noise pollution.
You're also not limited to just those 469 heliports. The vertices of the convex hull they produce can all serve as jumping off points to go about a 100 miles further to heliports one may have in ones own home.
For the rich in São Paulo, that may be homes in places like Angra do Reis and Laranjeiras. Even places like those two (which sit between Rio de Janeiro and São Paulo, can serve as connection points to jump from São Paulo to Rio de Janeiro with only one or two stops in between the two cities.
When you eliminate the time in traffic traffic to get to Congonhas or Guarulhos and the time spent in airport security, it makes a ton of sense for those with the means. Eventually as the tech progresses and becomes cheaper it will become accessible to more than just the very very rich.
I was actually very let down by the metro of Tokyo compared to other Asian cities. Probably due to my high expectations.
Electric motors are simple and reliable and all these companies use multiples so have some redundancy. Multi-rotors require computer control for stability. With that done the piloting is easy.
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.

And that's ignoring all of the problems with the market itself, not to mention regulations, as well as logistical headaches of transporting between rooftops (which by the way, many cannot safely support landing pads - so now you also have to retrofit skyscrapers with incredibly expensive infrastructure).
To be fair you answered my question and I'm just being belligerent, so thank you for the response.
You're basing this on a myriad of assumptions as eVTOL designs are barely at the prototype stage right now. Helicopters have been in use for decades, so we know how safe they are.
If they truly prove to be safer then that's awesome, but based on everything I've seen I don't believe that to be true.
Electric motors do not fail as often as combustion engines. Most eVTOL designs have redundancies that don't exist in a normal helicopter. I have flown R22s a handful of times and there were many times where an engine failure would have been disastrous.
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.
