'Truckers have to deal with a sort of standard "road safety dilemma" all the time...' I think you mean that truckers FEEL like they deal with that dilemma all the time. If they ACTUALLY dealt with an A or B dilemma, they would routinely end up in situation A or B: running over a passenger car or flipping the truck. It happens SOMETIMES, but infrequently. In reality the situations where other drivers do something stupid are probably much better handled by the self-driving truck, which doesn't panic, doesn't feel a fight-or-flight response, doesn't overstate the gravity of the situation... doesn't do anything except assess what to do next without emotion.
