With all the talk of self-driving cars, I figured self-driving trucks and buses wouldn’t be far behind. And here is a self-driving truck, already licensed in a few U.S. states. It sounds like there is still a human driver in it for now. But in the long term, I imagine this is bad news for human driver as an occupation. It should be good news for the safety of humans on the road in general. It seems like it could favor the economics of road freight vs. rail. Then again, it might make much narrower travel lanes practical, leaving plenty of room in the right of way for other infrastructure like high speed rail, high voltage lines, pipelines, etc. Time will tell.
