I think you are only telling the gloomy side of the story.

I think the answer might be nice if there's a better story.

Maybe not so much living without and riding bicycles and walking, but maybe more like:

- telecommuting - with government overriding 3-days-in-office ceo stuff

- goods delivery instead of shopping, maybe permits/regulations/etc to prevent 1000 delivery vehicles

- car rental, or fractional ownership, or something for exceptions

- rezoning/rebuilding so neighborhoods have some services within a short distance.
