Even the Dutch had to fight tooth and nail for it. I've lived in Germany for a while and there are cities here where even I would be snubbing taking kids to school with a bakfiets, because the biking infra is not good enough, or in other words the mingling I'd have to do with other traffic would be too out of my comfort zone.
Urban planning should prioritize walking and biking very first, and cars and other utilitarian-but-dangerous/harmful transport methods should be integrated in a way that's not engulfing the more human-scale side of things. But I think the costs (both monetary and in terms of "cognitive shift") are so high that I don't think I'll see this change in my lifetime. And that's before accounting for the power of corporate interest
