(I used to work for an autonomous truck company, and when you factor in the cost of roads in addition to the development of the trucks, it makes absolutely no sense to do autonomous trucking when you could do trains. As a culture, we've been brainwashed not to fund trains. We collectively spend billions and billions on roads but would not dare spend money to build more tracks. It is shocking and ludicrous, but that's what happens when you suck up a century of propaganda from the fossil fuel and automotive industry).
