Most of the modern world has common public transport, the US is a weird edge case.

You clearly haven't explored the modern world then. Or may have visited 3-5 cities and think you have seen it all. Some non-US metro areas where I found public transport to be inadequate based on my travels in the last 3-4 months - Toronto, Vancouver, Bangalore, Mumbai.

I've been to over 20 countries, many of which I'd consider modern world. I would have been to > 80 cities.

I spent months in both Vancouver and Torono without a car, and both have perfectly workable public transport systems, with Toronto's being a bit better. Both are better than every US city I've been to, and scooters replace neither.

India is a third world country with a pretty low standard of living. I haven't been to Bangalore or Mumbai, but I can't imagine them being relevant to this discussion.

> both have perfectly workable public transport systems

Only if you confine yourself to downtowns. Which is why I said metro areas.

> India is a third world country

It is a third world country with lots of modern parts. If you don't think Mumbai or Bangalore or modern cities, that just means you have a very different definition of what modern means.

You seems to have missed the context of this comment chain. We were discussing cities. I have no idea what a "metro" or "downtown" is.

> I’d be careful about extrapolating these results across cities. In most American cities, for example, I’m going to replace an e-scooter with an Uber.

I also never said modern cities, I said "the modern world", of which India would generally not be considered part of. I may have defined that poorly though, my bad.
