Auto group backs guidelines for partially automated vehicles

The trade association representing most major automakers is offering guidelines for manufacturers to advertise partially automated driving systems and make sure drivers are paying attention while using them

DETROIT -- The trade association representing most major automakers is offering guidelines for manufacturers to advertise partially automated driving systems and to make sure drivers are paying attention while using them. The Alliance for Automotive Innovation says its members support the voluntary principles, which come as two federal agencies increase scrutiny of Tesla's Autopilot diver-assist system after two men were killed in a fiery crash near Houston. Such systems can keep vehicles centered in their lane and a safe distance behind traffic in front of them. But Teslas on Autopilot have been involved in multiple crashes, including several fatalities, when neither the system nor the driver intervened. The Teslas have had trouble handling stopped emergency vehicles or tractor-trailers crossing in front of the cars. Critics, including some legislators, have said the name Autopilot is deceptive and implies that the cars can drive themselves. The alliance, which represents at least 20 automakers including General Motors, Ford and Toyota, released the principles ahead of a U.S. Senate subcommittee hearing Tuesday on the future of automotive safety and technology.
