All done with AI and autonmous driving.
Neither of those things exist though, despite a lot of hype around at the minute.
Especially AI in any sort of broad meaning of the term. An automobile visual system that can make a value judgement to run over a dog instead of a child in a split second where those two things run out onto the road and it's too late to brake - are we any closer to that than we were 20 years ago?
I think if it's work commuting we're trying to eliminate then decentralisation and serious adoption of homeworking would be a more realistic goal.
