Self-Driving Trucks Will Always Need People

We all know how a self-driving vehicle is supposed to act, thanks to companies and startups like Waymoand Uber: These cars and trucks should be outfitted with enough sensors and computing power to put all humans in the passenger seat.

But that rosy vision ignores current laws and practices. For example, while California has approved autonomous-vehicle testing without a safety driver since February 2018, those vehicles must still have a remote operator who can step in to pilot the car in an emergency. It’s not sexy, but the big secret of autonomous cars is that there’s still a human behind many of them.
