U.S. magazine Consumer Reports on Thursday urged electric car maker Tesla Motors to disable the automatic steering function in its Autopilot driving-assist system, which is under investigation by U.S. regulators after a fatal crash.
Consumer Reports, which has 8 million subscribers and issues annual ratings of cars, wants Tesla to disable the current system, require drivers to keep their hands on the wheel as part of an updated driver assist system and stop referring to the product as Autopilot.
The U.S. National Highway Traffic Safety Administration is investigating the May 7 crash and death in Florida of a Model S driver who was using Autopilot.
Consumer Reports said the Autopilot name "promotes a potentially dangerous assumption that the Model S is capable of driving on its own."
"By marketing their feature as 'Autopilot,' Tesla gives consumers a false sense of security," said Laura MacCleery, vice president of consumer policy and mobilization for Consumer Reports.
"We're deeply concerned that consumers are being sold a pile of promises about unproven technology. 'Autopilot' can't actually drive the car, yet it allows consumers to have their hands off the steering wheel for minutes at a time."
Consumer Reports also urged Tesla fully test safety systems before public deployment.
Tesla didn't immediately respond to a request for comment Thursday, but Consumer Reports included a statement from the company defending the system.
"While we appreciate well-meaning advice from any individual or group, we make our decisions on the basis of real-world data, not speculation by media," Tesla's statement said.
Tesla, in a blog post in June about the crash, described Autopilot as being in a "public beta phase" and said customers have to opt in before activation. Chief executive Elon Musk tweeted on July 10 that "beta" means "any system (with) less than 1B miles of real world driving."
