Even so there are only 469 (in 2008 according to the article) in all of São Paulo and that’s the metro area with the most helicopters in the world.

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'd be surprised how far 469 heliports go. That's one more than the number of stations the NY Metro has, which is the metro with the most number of stations in the world. Now imagine you could travel as the crow flies between any station in NYC. That's awesome efficiency, and if you still need you can grab an Uber at street level if you're still not close enough.

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.

No. Seoul Metro has nearly double that of NYC. I have no idea how you could possibly think NYC has the most in the world. Just think of most Chinese cities, let alone Korea's capital. https://en.wikipedia.org/wiki/Seoul_Metropolitan_Subway

Also Tokyo, Japan. It's ranked first in the world on subway usage and has 882 railway stations. https://en.m.wikipedia.org/wiki/Tokyo_subway

Actually Tokyo has much less than Seoul. You're counting railway stations, not subway stations. There's a large difference. Though the water is quite muddled, the easiest way is to actually look at the maps of the differing cities.

I was actually very let down by the metro of Tokyo compared to other Asian cities. Probably due to my high expectations.

Thanks for the correction. Google failed me when I tried to look up the metro with the most number of stops.
