I’m guessing that a lot of trucks will just wait on the shoulder until it is safe to proceed. Once the tech is good enough, loosing an occasional cargo because it goes bad on the side of the road will probably be cheaper than paying to send someone along with the trucks all the time.
Heck, after a certain point, trucks may not even have a human interface or passenger compartment at all. Switches are surprisingly expensive, after all…
(And yes, the “solution” of expecting a human to take the wheel at 60MPH is ridiculous and is a horrible notion. It’s probably OK for the car to give the human that option if there is time, but if the car can’t pull over and stop itself if the human doesn’t grab the wheel, that is a lousy design. If the vehicle expects the driver to grab the wheel to correct it’s mistake, it’s a lousy design. We shouldn’t allow either design on the roads.)
