The flatness imo only lends itself particularly well to their dutch bikes, but nothing to do with whether a region has invested in their biking infrastructure.

Plenty of places are flat, and plenty of those flat places are horrible car-infested hellscapes that are falling apart. There's nothing particular unique about the Netherlands. Fwiw, I'm very much pro car-last infrastructure.
