What about actually making public transit usable? That doesn't require years of R&D and solving several "unknown unknowns".

Instead we get companies doing R&D of unproven technologies on public roads because no one wants to build more rail.

For some eye-popping numbers, check out the automotive deaths/100,000 people for the US (12.9) vs. Denmark (3.4)[1]. Denmark doesn't have some magical AI that makes all their cars safe, just better infrastructure.

Denmark has a much higher bar for obtaining a drivers license, both in terms of the education and demonstrated skill required, and the cost of the license.

If US drivers had to meet the same standards as Danish drivers in order to get a license, our roads would be a lot safer.

Another good solution that requires zero R&D.

It's frustrating to see traffic fatalities trotted out as a "the ends justify the means" justification for self-driving R&D budgets and practices as if there are no other solutions to the problem.

It probably wouldn't. A VERY high proportion of the most risky drivers on US roads are already driving illegally. For example, nearly 1/3 of drivers in Mississippi are driving around without insurance.

If people are given a choice between driving illegally and going without basic necessities, they choose the former.

A lot of people end up in this situation because they are bad drivers with bad records, and can't afford the insurance, so they drive illegally. Functionally this is no different than if they weren't able to get a drivers license. They are still on the road.

Lax licensing is not the cause of bad drivers in the US. Both the bad drivers and the lax licensing is caused by a lack of transportation availability.

Well the other thing about Denmark and many other European countries is that cars are also much more expensive to buy, to own, to register, etc. so people who are on the verge of not having basic necessities certainly cannot afford a car. So the people who are driving are by and large people who have something to lose by flouting the law, which tends to make them act more responsibly.

but in the US you have freedom of movement also most of the US is rural and driving is basically a right because if you don't you're a nobody and can't function. Ironically Japan is having an issue right now with lots of rural grandpas aging out of driving competently and having no alternative.

Freedom of movement doesn't mean freedom to operate any kind of machine anywhere you wish however you wish. Denying you a driver's license isn't denying you the ability to go between the states. Sure you can go from CA to NV, go take a bus or the train or fly in a plane or have a friend drive you or bounce over there on a pogo stick or roll in on a unicycle.

Public transit isn't usable because we don't build housing dense enough.

For example, Seattle area just spent tens of billions on light rail expansion, then built the outlying stations next to the freeway. Half the walkable distance is wasted. Then they build parking garages and zero amenities. They're surrounded by dangerous parking lot and multi-lane roads. It's not designed to actually be used by enough volume to matter! And even if people did come (which they won't) it can't handle more than a small portion of the existing traffic because it's too slow and can't be expanded and can't have express routes.

This is the best we get, for tens of billions!

The closest house to these stations is ~10 minute walk. There are massive parking garages, but basically no accommodations for bikes (paths upon arrival or parking). All ugly concrete slabs with no covering from the sun or elements (outside the station, for connecting transit).

Luckily it never rains here, so don't worry about getting wet...

One of the current weaknesses in public transit is that it requires a minimum population density before it becomes viable. The entire way we think about public transit today presumes that it makes sense to send a vehicle with many seats along a fixed route.

Self driving vehicles could be the innovation that makes public transit usable in non-dense areas. We could do dynamic routing based on the demand of the riders.
