Yeah, I've always understood that to be the big initial play— get all those long-haul trucking miles autonomous, relegate human drivers to handling the in-city miles and cargo yards. I think Ottomotto (remember them?) might have even made a video years ago which pitched this exact scheme.

Of course, the environmentalist in me is saddened by the thought of further driving down the cost of that shipping mode which might be most compatible with being switched to rail freight.
