That's BS about being capable of navigating Interstate highways autonomously.
Whoever does the research needs go actually go along an Over The Road truck driver and actually see what challenges technology face.
Different highways with crumpling road markers.
Severe weather.
Unpredictable human drivers.
Fueling.
Construction sites and their differences between displaying markers.
I do not see autonomous technology taking over long haul truckers anytime soon, especially if the state and federal government doesn't maintain the highways and keeps cutting budget.
The few scenarios where the present technology can handle is a local route that has greatly maintained roads and stable weather. Even in this case, it's foolish to think human drivers will not be as careless as before. In fact, I predict they will think its so safe that they will cut the truck off ever closer, thus creating more disasters.
