Don't forget on the fly maintenance. Anyone who thinks that it should just "work" is probably the regular mechanic. Important guys to be sure but sometimes things need to happen on the road to get things done on time.
Think of this as a function of time. Probably a lot cheaper to have a network of people able to service big rigs available throughout the country on short notice than to pay them to sit in the truck all day, except where the cost of a delay exceeds a certain threshold--i.e. the cost of paying to have a mechanic sit in the self-driving truck adjusted by the probability of it breaking down.
