Steve Viscelli of the School of Arts and Sciences spoke about the impact of driverless trucks on the trucking industry. “I’ve identified two segments that I think are most at-risk. And that’s refrigerated and dry van truckload. And those constitute about 200,000 trucking jobs,” he said. “And then what’s called line haul, and they’re somewhere in the neighborhood of 80,000-90,000 jobs there.”
