Not to mention, the extreme variety of loads and weights, as well as real world variations of identical trucks. Castrated trucks need not apply. The heaviest (slowest) truck will have to be the lead. Then, let's imagine the effect of "ghost braking".
Flat ground, identical load factors, compatible power to weight ratios, and irrational trust in the technologies, would all be required. Seem to make this concept a distant fantasy, suitable only in isolated cases, IMHO.
Sure, one of these days will come in some form. But just because it can be done, doesn't mean it should (or must) be done.
