Reading https://en.wikipedia.org/wiki/Demography_of_the_Netherlands#..., the population of the Netherlands about doubled since 1945, so the vast majority of its cities may predate cars, but the vast majority of its neighborhoods won’t.

I expect average household size to have decreased significantly, so it wouldn’t surprise me if at least 75% of inhabitants lived in post-war houses.

Because of that, I don’t see suburban construction as a major difference between the USA and the Netherlands.

A major difference likely is that the USA has room for sprawl, while the Netherlands doesn’t. Dutch suburbs likely are more dense than ones in the USA.
