The Long Road to Driverless Trucks

Restricting these trucks to the highway also plays to their strengths. “The biggest problems for long-haul truckers are fatigue, distraction and boredom,” Mr. Rodrigues explained on a recent afternoon as one of his company’s trucks cruised down a highway in Northern California. “Robots don’t have a problem with any of that.”

It’s a sound strategy, but even this will require years of additional development.

Part of the challenge is technical. Though self-driving trucks can handle most of what happens on a highway — merging into traffic from an on-ramp, changing lanes, slowing for cars stopped on the shoulder — companies are still working to ensure they can respond to less common situations, like a sudden three-car pileup.
