Except we now have cars with self-driving (however limited, it's a massive improvement over a car from 30 years).

Another interesting thought experiment is, how many digital services, modern tech and so on would you be willing to trade for something mundane, say your dishwasher, a hot shower, the toilet, a car, soap, if you could only have one or the other?

I would absolutely choose a mobile phone over any of those things.
