But it works? We only have functional public transit in small amount of cities in NA as well. If we can scale it up, it might be a game changer. I’m as pro-transit as it gets, but unfortunately we don’t have political appetite for it.
Rather sad though that instead of implementing what empirically is already known to work in so many cities there's a quest for a solution to a problem that's completely self-inflicted.
Self-driving might help a bit with transportation in NA cities but it definitely won't be the solution, there's just not enough physical space on the roads to be a game changer, at worst it will create even more issues with road usage. And my fear is that instead of realising it was the wrong bet (just like the car-centric approach) it will be doubled down into some ever-more-complex maze of solutions to make cars transporting 1-2 passengers to get to their destinations quicker by interconnecting them, and doing traffic management on a network of cars.
Those are fun problems to think about and try to solve but completely missing the mark about what actually works for a city and why. Someone will call that "innovation" and sell it to some suckers, just like car-centric urbanism.
Why not just build trains? They don't need technological breakthroughs, there's existing expertise all around the world on how to build; are much more easily automated (even more underground); can transport lots more people than busses; scheduling is much easier, etc.
I don't know what about the American culture creates this magical thinking, if it's the short-term thinking, the culture of looking for business opportunities everywhere, the inability to approach complex systems in a more holistically way, and/or the hyper-individualistic view of society.
No single technology will be the silver bullet, transportation (as any complex system) requires layers of solutions, maybe automated vehicles are part of it but there's already technology to solve 80% of the issues, it's unfortunate the USA doesn't have the will to change its ways to proven solutions and keeps chasing its tail.
