@hughster The people I mainly had in mind are from Belize and Nepal. Note, though, that I never said the people I was referring to grew up in and had to "escape" poverty; that was an assumption you made. I just said they grew up in villages and didn't have cars. The former came from a family that would probably be considered middle-income by her home country's standards and apparently had a reasonably comfortable upbringing there, but was not affluent by "first world" standards.
But that just illustrates my point, which I think you're still missing. In many parts of the world, even rural people who are reasonably well off economically typically don't own cars because regardless of where they live, it's unusual that private car ownership actually makes more economic sense than using things like buses. It's just hard for us to see that because our governments use very heavy subsidies to aggressively distort the market in favor of private cars.
