Do you have links to those computer models? Do they take into account induced demand?
And still, even if autonomous cars are drastically more efficient, with a passenger per car the space use is still drastically less efficient (even the biggest highways will have a fraction of the capacity of a proper metro).
You're more than capable of doing this research yourself.
> with a passenger per car the space use is still drastically less efficient
Sorry, this simply isn't the metric for success. It might be your metric, but it certainly isn't the population's metric. A lot of people want to travel comfortably in cars, "mindless pursuit of space efficiency" be damned.
Ubiquitous self-driving vehicles will allow us to eventually eliminate most congestion, and you're just going to have to accept that cars aren't going anywhere.
How would they eliminate congestion when they're so space inefficient? Even if they're more efficient at traffic flow, there's only so much physical capacity on the roads that people want to travel on.
> you're just going to have to accept that cars aren't going anywhere.
Cars aren't going anywhere, but they're the wrong solution for a variety of reasons (congestion leading to time loss, pollution (including noise pollution), land use efficiency or lack thereof, etc.) for a very big part of transportation needs.
> A lot of people want to travel comfortably in car
And a lot don't and aren't given that option.
> "mindless pursuit of space efficiency" be damned.
Mindless? There's only so much physical space available in the places where people live and work. American cities are often comprised of massive parking lots taking up valuable space that can be put to much better use, simply because most people are forced to commute by car. Give them another option and many (of course not all) would prefer it, which would also make driving much more pleasant for the remaining drivers.

Sure, but that's not the limiting factor at all, which you'd understand if you bothered to do the slightest bit of research outside of your comfort zone.
> And a lot don't and aren't given that option.
That's very true, but it's not one-or-the-other. I am a strong supporter for intensive funding of mass transit systems....for those who want to use them. But that doesn't preclude continued usage of cars.
> massive parking lots taking up valuable space that can be put to much better use
"better" is in the eye of beholder. Car users are generally okay with how space is currently allocated.
If you want change towards increased mass transit, I highly recommend not being hostile about it. There is no need for mass transit to be positioned as a replacement for car use. When you threaten peoples' way of life, that's how you get people actively working against you.
It should come as no surprise that I'm a huge fan of getting around by car, but I would still happily have my tax money go towards bolstering mass transit systems and walkable/cyclable infrastructure for the portion of the population that wants to commute that way.
And still, even if autonomous cars are drastically more efficient, with a passenger per car the space use is still drastically less efficient (even the biggest highways will have a fraction of the capacity of a proper metro).
