Put it another way, would you buy a car if you cannot use it for daily work commute? I think for a lot of people the answer is obviously no.

Sure wouldn’t, and for what it’s worth that’s why the scenario is a great litmus test. If it can do that, it should be able to handle anything else thrown at it

Except we already do have that technology, its not a fancy robot, but trains. I wouldn't consider buying a car in Tokyo.
