The US got this way because it was super-charged between pre-WWII and the dotcom boom. Both economically and culturally. The post-WWII high wages allowed the rise of suburbia, the Cold War induced WW3 scare led to the highway system, and so on.
The low-efficiency of it is taking its toll. (Sitting in traffic for hours each day, pollution, etc.)
And I'm not saying there are no benefits, nor am I saying that the alternatives are so perfect people just somehow don't see it. (I'm saying let's quantify the costs and let people choose. For example I'd spend a lot more on soundproofing and a lot less on backyards and frown lawns, but mostly there's no such option. [Hence the big push for more permissive zoning/permitting/etc.])
Car infrastructure spreads everything out, puts parking lots everywhere, makes walking or cycling impossible or really unpleasant. You can't have working public transit if visiting two businesses requires walking 10 minutes along a loud boulevard.
America has tried cars-first infrastructure. It has failed. The spread is unsustainable, and it's bankrupting suburban areas.
Here is an idea, build public transports so that less people use the car infrastructure, and just like that you get higher utility out of your existing car infrastructure.
Seriously, the amount of 8 way stroads in the US is a fucking joke. There is essentially never a need for an 8 way road anywhere at any time. And for sure not absurd 20 way highways.
