I mean the US is heavily car centric. Self driving cars are an attempt to adapt to what the reality of the world currently is.
We should absolutely be doing things to make cars less of a requirement by improving public transit and creating more livable spaces that don’t require cars, that can even be the primary goal, but it won’t eliminate cars completely, and if it does it will take A LOT longer than self driving cars.
Self driving cars are a great idea, but they aren’t a fix everything solution, they just one part of an overall solution.
Quick edit: Also the cars Musk is developing are not even close to what we need. He’s being deliberately obtuse and creating more problems than he’s solving.
Paradoxically, the large scale deployment of self driving cars will improve the walkability of neighborhoods by reducing the demand for parking.
One can also envision building on self driving tech to electronically couple closely spaced cars so that more passengers can fit in a given area, such that throughout of passenger miles per hour can increase several times over. Cars could tailgate like virtual train cars following each other at highway speeds with very little separation, lanes could be narrowed to fit more cars side by side in traffic, etc.
How will it reduce demand for parking? Do you envision the car will drop someone off and then drive away until it finds a parking spot that’s farther than the person would want to walk?
That sounds like a very hard problem , and people wouldn’t be happy waiting 5-10 minutes for their car to navigate back to them. Or it would just cruise around looking for parking, causing more traffic.

It’s still early. We still need more data. They should be closely watched. But self driving cars do appear to be safer. That’s why they are a great idea. They are making driving and roads better.
I don’t have the means or motivation to do research now from the couch, so I’ll concede you may be correct. However, I think it might be even safer to take those same billions of dollars and invest them in mass transit and other infrastructure changes. That would mean fewer car accidents, less pollution, nicer spaces, healthier people, healthier economies, etc. private car ownership cannot be the long term solution. If it’s not an outright dead end, it’s certainly a side street instead of high speed rail (if you’ll pardon a strained metaphor).
The challenge is one approach only needs to modify the transit infrastructure. The other means having to tear down and build new commercial and residential properties and force people and businesses to relocate in order to have a vaguely sane transit system. My area desperately wanted to do transit but even with rather significant hypothetical funding, they could only service about 10-15% of typical trips. They’ve settled on a plan that is much less money, but only serves like 5% of trips. To go with that plan, they are making restrictions around zoning to force mid density mixed use construction only, favoring one of the two chosen transit corridors.
They are trying but just people are distributed very awkwardly for mass transit.
To be fair I don’t have 100% confidence that self driving is safer than human driving. I just believe that based on the current data, it seems to be. If new data comes out tomorrow, then I’ll look at and evaluate that data.
I also don’t believe that investment is a zero sum game. We should absolutely be investing in both. Both are valuable. You don’t have to only invest in one.

Why are they a great idea? What are they making better? How is it worth the real and opportunity costs?

Once again reinventing buses and trains
They’re safer than human drivers. Tesla cars absolutely are not. But Waymo cars? They do seem to be.

It took like 100 years to build the car-hell we have now. It’s going to take a lot of time and effort to fix it.
And people are, famously, stupid. They’ll fight like hell to avoid change, but once it’s in they’ll fight like hell to keep that change.
Plus there’s a lot of selfish idiots that need to be overridden.
I believe china has self driving trains.
What does this have to do with self driving cars in America?
