Look here, another promise by Elon Musk.
Anyone think this will actually happen?
Interesting how things that could be automated much more easily (buses, trains, mail delivery) are not tried first.
Maybe there is no glamour in those things.
Musk has a knack for making crazy promises.
My believe is he is trying to distract us from other things that may not be performing to task.
There was another historical inventor that did a very similar thing.
