The stupid thing is that fixing it isn’t even that hard.
Step one Get rid stupid zoning laws like single family housing and reduce parking minimums.
Step 2 Modify existing roads piece by piece to include alternative transit methods. Add bike lanes, if you can’t slow down roads and people will bike.
Actually run decent buses where peoole want to go, not oversized 50 person buses on 3 routes that nobody uses becasue it doesn’t go anywhere, and has an hour between the next bus.
That’s it, the market will build more housing in areas that need it if its profitable, then use that new tax money to drive transit infrastructure.
There’s a lot of fine details, but we’re bankrupting cities with cars right now.
The newer technology at that time was cars and roads, and many European countries did try the American system of roads and suburbs.
Its just that most of them realized it wad a bad idea around 20 years ago and started rethinking their cities.
Many city centers were even turned into parking lots like American ones.
Again cities arent supposed to be static, and normally they grow denser, rather than sprawling.
The problem with American cities is partly zoning, and partly nimbyism, where people don’t want their places to change.
And sprawl sucks for pretty much everyone. Less arable land for farming, poorer anmeties, longer travel times, and finally huge transportation costs. Cars are by far the most costly method of travel, both personally and for governments.
