If there were free taxi services (or other transit), kids would be fine.
And honestly, most of the evil comes from overly-empowering parents. "I don't think you should go there / do that / hang out with those friends" is toxic.
Healthier, as kids mature, for them to be able to do things that parents disapprove of... but can't stop. While still allowing prevention of serious choices.
Making kids dependent on parents' cars increases parents' power from "I can speak out about things I disagree with" to "My agreement is required for anything to happen."
And that's really not healthy, for the kid or the parent.
I think it would be great if kids could take themselves to gymnastics practice on public transit. But giving them the choice between that and smoking pot with friends? I think the choice hurts rather than helps.
Last I looked it up, there were pretty serious mental health issues associated with the tiger parenting technique.
Kids need parks, sports fields, cinemas, hobby stores, places to get food, etc, and they need them within walking distance. Being virtually dependent on cars to get anywhere is very crippling for kids.
