Robot Trucks on Texas Highways Herald Era of Driverless Big Rigs

After lumbering through a gravel parking lot like a big blue bull, one of Aurora Innovation Inc.’s self-driving truck prototypes took a wide right turn onto a frontage road near Dallas. The steering wheel spun through the half-clasped hands of its human operator, whose touch may not be needed much longer.

Fittingly for Texas, these Peterbilts are adorned with a sensor display above the windshield that looks much like a set of longhorns. This was the beginning of a 28-mile jaunt up and down Interstate 45 toward Houston in a truck with a computer for a brain, and cameras, radar and lidar sensors for eyes, capturing objects more than 400 meters (437 yards) out in all directions.
