>That difference no longer exists in the US in any practical way because technology has obsoleted the legal mechanism of “you can’t ask for my drivers license without probable cause”.

Are you sure this is quite as absolute and one-way as you’re saying here? ID isn’t required by government to be driven, use public transport, fly on private aircraft, use boats, etc. Sure as a practical matter in the US non-car options are not nearly as powerful as in most first world countries, but that’s not a matter of law. And while technology helped create the current state of affairs, it can disrupt it too. The motivation for drivers licenses is a real one of public safety. If self-driving cars mean most people cease manual driving though, the need for licenses will cease as well (and also most of the typical suspicions and justifications police use to pull over a car). That may result in a significant clawback of travel privacy in some respects. Practical is not always the equivalent of legal long term is it?

If the true purpose of a drivers license was public safety there are surely a large number of people who wouldn't be permitted to operate a motor vehicle. Or at the very least we would be required to periodically prove our competency.

That's silly. Driving in America at least is a quasi-right: while not technically a right by law, as things stand the economy and much of society in the country would collapse if most adults were not able to drive. But at the same time driving is not natural and definitely represents real danger. So the law reflects a balance between these two competing interests, with safety concerns slowly getting pushed harder over time. Driving requirements are relatively forgiving, and removal is taken seriously. But there are a lot of laws and thinking around how to improve safety. The licensing process has become more of a ramp too, with many (all?) states having increasingly graduated licensing and some starting to have rechecks needed for the elderly. Licensing for non-necessity driving (commercial vehicles, motorbikes etc) sees a significant spike in requirements.

People very much care. In highschool I had a good friend hit and killed by a drunk driver while they were walking right near school, and I would strongly resent any putting down of how devastating that was for the family and our group. But "individualized mechanized arbitrary point to point transportation" is also very much critical, and with current technology that means "a human driving". It's very unfairly glib to impugn that society isn't trying to balance here. What is needed to radically change the status quo is to finish the car technology so that a human is not needed. Once that is the case and manual driving becomes a fun luxury I expect we'll see licensing requirements and training increase a great deal, looking more like what professional motor racers do. The converse from a privacy perspective is that no, many people will not bother to carry drivers licenses with them anymore, nor will they need to.

Generalized authentication is and should be an important role of government, so some form of ID will still matter. But in terms of needing to have it on you? No, I do not think that legal requirements around that will change. The "true purpose" of a drivers license is in fact trying to have some minimum level of competence and personal responsibility attached to the act of personally controlling a multi-ton pile of metal moving at high speeds.
