First of all, it probably won’t. But more importantly, even if it does, 20% or more of your remaining healthy lifespan will elapse while it’s happening.
Don’t wait. Carpe deambulatio.
And broadly speaking, while that may be good for the individual I don't think it's good for society. We need some people fighting for walkable cities where they are, else we'll never get any more of them. And the highway widenings continue unabated...
Usually it takes something bad happening.
I also don't think a lot of the changes people want will be coming to US cities as quickly as they hope. I've worked in the architecture/urban planning world and despite the people doing that work knowing what's best for a city, it's the engineers, politicians, and people with money that end up making the decisions unless there is some very vocal asks. There's also a ton of red tape that stands in the way, especially in CA, of anything being built in a timely, cost-efficient manner.
One can hope though. Small stabs at progress are being made.
I agree, and not really sure why there are so many posts on this topic on HN - there are plenty of places to move and live if you want to be someplace where you can walk to or bike to.
There are also plenty of places where you can move to, buy a bit of land with a SFH and enjoy that lifestyle if that is what you prefer.
Why do some people have such a strong need to tell other people how they should live? or expect them to change to suit someone else's idea of what is 'better'.
You might say that the people who want to drive cars everywhere are telling the walkability folks how to live. I just want to live in a walkable and bikeable place where I'm safe from aggressive car drivers within a few hours of friends and family. That place sadly does not exist. Would it be so wild to make a few neighborhoods in the US a bit more human-centric and a bit less car-centric? It doesn't have to change everything. Just a small number of cities and towns.
