It will also have to be public transport realistically, but what seemed to be most convincing to the people around me is individual health benefits, we have shocking obesity rates in the UK so me being a somewhat skinny fat lady with an overweight BMI without a big stomach has literally got people asking me how I do it, and I tell them I walk everywhere. It's kind of a lie though because exercise doesn't make you lose weight, but it's a white lie since I also have decent health despite no actual exercise and I do actually credit that to walking and believe my car driving peers could stand to benefit.

Obviously this is already with walkable infrastructure in place. The road to get there in North America is much longer and harder and in the US it will require far more fundamental cultural and societal shifts in the direction opposite to the one y'all are on now, like less racism, less white flight and landlordism in suburbs, more welfare to reduce crime and inequality and more cultural cohesion to draw people to cities, and then infrastructure to practically rebuild streets from scratch with dense, mixed-zone housing and walkable yet modern and spacious designs that won't be too europoor style (which sucks too tbqh) so as not to cause a backlash.
