Once vehicles are
fully autonomous (Level 5, IIRC), technically
and legally, the options are almost unlimited.....
I may be retired by then, but for me I'd be interested in commuting options with Level 5. Buy one with a sleep chamber - if a high-paying job is 3 hours away, no problem !
As much as I will continue to poke at the technology with a sharp stick (well, not really only that..... more so tilting at the windmill of people's blind-faith in tech

....), what may take longer to fully settle out are the Legal issues.
We can have bad Winter storms here, that fully able-bodied people think twice about heading out in. Where does the liability lie when a non-driving senior with major health issues gets stranded in a Winter storm, and perishes ? We've touched on this aspect a bit here, but that example highlights the case of someone who not only does not hold a DL any longer, but may not have any real driving skills still available, even in an emergency.
One response can be "The trip shouldn't have been initiated to begin with", with some validity. People of all ages and abilities can and do make sub-optimal driving decisions already.... I just don't want to see people making
more of them by putting on the
Blind-Faith in Technology Blinders......
I don't think the Elephant in the Room has been mentioned......
Want to go the bar, and have a dozen drinks ? Legally, I'd say that will be the acid-test for Level 5.
