I do not want to be against having less car dependency and more walkable cities. The problem is that most of the advocates for these policies have a package deal of other politics that are naive leftist crap.
"[Mostly homogenous and high country] has better city design than in the US! We should be more like them." Which ignores that we have a diverse (and therefore low trust) society in the US. We cannot pretend that city planning will solve problems that come with diversity.
I forgot to mention crime, which no shock, these people also want to be soft on crime. No, your city planning policies will not fix crime (despite their claims) if you are not going to make sure to harshly punish these crimes.
Hey, maybe people do not want to worry that they are going to be beaten and/or mugged on public transit, so they would prefer to be safe in their own cars instead. Is that possible? Oh, you want to blame the symptoms for the problem rather than being soft on crime policy.
