Chips developed by domestic autonomous driving solution provider Horizon Robotics are displayed at the WAIC 2019 in Shanghai.

US Transportation Secretary Anthony Foxx said the federal government intends to set the safety standards for cars of the future where no human is involved in the driving, even while individual states still regulate cars with humans behind the wheel. But some of the rules will extend to advanced driver-assistance systems, like those in Teslas, that can handle significant levels of driving even while demanding a person stay at the wheel of the car, officials said. Announcing a 15-point safety assessment for driverless car systems, Foxx stressed that the government wants to work with developers--which include most large automakers as well as tech giants such as Uber and Alphabet (Google)--without stifling their efforts. "This area we recognize as an evolving area. This is an emerging technology," he announced.
