sensors would be passive, thus no maintenance. 10,000$ every 200m is stupid. You use RFID chips or similar things. I don't know how often signs are replaced, but at some point every sign should come with an RFID chip that encodes information about it, although you can probably just glue a chip onto a sign as well. We scoff at Tesla's self driving claims and the valley between their "FSD" and actual required products, but they'll keep hammering at it. There's probably a trillion dollars of valuation for solving it. Musk's current managerial incompetence aside, Tesla DOES have the data collection platform to get all the data needed for self-driving, especially the "easier" stuff. Once enough cargo is moving along a route, if there's sections of that route that are not ideal for automated movement, that will be brought to attention of the transportation agency. The value proposition is obvious: generally, interstate highways are almost totally unutilized from about 10pm to 5am (outside of cities). 6-7 hours of transit that could be used (and offload the transit from rush hour times when passenger cars demand it more).
