Yeah, back then I also thought that a leader-follower convoying system would be implemented first (with local drivers for the last mile problem), because that system made sense and was straightforward- with good logistics software (to make sure that the leader is driving the farthest distance or connecting multiple leaders together) you could easily save 2/3 or more of your driver costs. Then a few years ago I talked to an actual software consultant to shipping companies, and asked him why none of that had happened in over a decade. He felt was that the companies were too fragmented for that. Most shipping companies are small companies, where basically the owners wife keeps a list of all of their shipping loads and destinations. Maybe Walmart has the access to capital to acquire that technology and the scale to profit from it, but he felt that no one else could. Which was why he left that field and went into industrial robotics, where the business case can actually close.
