Then you can access those things 10m away in a similar amount of time.
For large items you'd use a car or pickup for, businesses would adapt by offering delivery.
It's definitely possible, but the infrastructure investment would be gargantuan.
Use is infrequent, meaning it would either have to be subsidized, which never makes folks in the city happy, or cost an arm and a leg per trip, making it impractical for rural users.
With that population density it's never going to make sense to put something like light rail on that route. So these people will continue to use cars. And that's fine.. hopefully cars continue to get safer and easier on the environment.
I think it's the urban/suburban sprawls akin to LA that really could benefit from better transit/walkability.
Same day is a bit of a sticker but you can find towns near major areas where you won’t need your car most days (assuming you can find work).
No, what you describe is a poorly designed area.
The most charming, vibrant and yet quiet districts of Tokyo or Seoul are densely populated.
So what would a car-less community I could tolerate look like? Probably a lot like it does right now, just with more commercial entities within a mile or two of my home. It would also be a lot harder for me to access bigger commercial entities (like Walmart, Target, et.al.) since it would involve public transit that is about an hour and a half away (it's 10m by car, fwiw) in a higher density (and cost) city.
