Car based transportation is just not scalable.

Other countries have figured this out. Norway in particular. Working transportation models exist and this country has the funds to make it happen. However because of American Exceptionalism, we have very limited options.

I'll add another country with even better public transport (especially trains) - Switzerland. A small, dense and very wealthy country that has train station at the heart of every city and many villages, and the rest is covered by buses.

Yet every single morning and evening there is huge traffic jam around every city. Every single year highways are more full, more issue with parking.

If it can't be solved in such ideal country for public transport, I am not holding breath for rest of the world, and just wishing something ain't gonna make it real. There are many reasons why situation is as it is (it costs a lot, even such transport doesn't cover many people's cases well enough and nobody wants to spend 120 mins every day commuting via public transport when its say 60 with cars).

What I can imagine actually working - uber style shared robo (meaning cheap) taxis/minibuses. Big enough network that one can even switch a car in some 'taxi station' for more efficient trip that would take just marginally longer than driving oneself. This solves a lot of parking issues in cities and would reduce traffic to maybe half or a bit less.

This. This, this, this. I cannot stress enough how critical this point is. Either we invest a trillion dollars in electrifying parking spots or we invest that in building out transit and bicycling systems. None of them will ever be profitable over the long-run, so we continue with gas vehicles. I would so much prefer not to have to drive to the grocery store when I don't have 2 hours round-trip to spare on four intersecting transit schedules, or to risk life and limb every time I want to try and bicycle those 2.5 deadly miles across four highway on/offramps where vehicles ignore every "no turn on red" sign in the region and police that don't enforce.

Banning gasoline vehicles is the goal. In the U.S., all known solutions require capital investments that corporations can't extract a 'growth in profit growth over time' from, while disadvantaging the vehicle owners caste. Solve that, and you'll solve a lot more than just gasoline vehicles.

We have scaled it! We're a country of 330 million people where almost everyone drives.

It's only "American Exceptionalism" insofar as Americans are rich compared to Europeans. Upper middle class people across Europe also live in suburbs and drive to places. American wealth/land space simply enables middle and lower middle class people to do the same thing.
