Feds reviewing Musk tweet about disabling driver monitoring

DETROIT (AP) — A tweet from Elon Musk indicating that Tesla might allow some owners who are testing a “Full Self-Driving” system to disable an alert that reminds them to keep their hands on the steering wheel has drawn attention from U.S. safety regulators.

The National Highway Traffic Safety Administration says it asked Tesla for more information about the tweet. Last week, the agency said the issue is now part of a broader investigation into at least 14 Teslas that have crashed into emergency vehicles while using the Autopilot driver assist system.

Since 2021, Tesla has been beta-testing “Full Self-Driving” using owners who haven't been trained on the system but are actively monitored by the company. Earlier this year, Tesla said 160,000, roughly 15% of Teslas now on U.S. roads, were participating. A wider distribution of the software was to be rolled out late in 2022.

Despite the name, Tesla still says on its website that the cars can't drive themselves. Teslas using “Full Self-Driving” can navigate roads themselves in many cases, but experts say the system can make mistakes. "We’re not saying it’s quite ready to have no one behind the wheel,” CEO Musk said in October.

On New Year’s Eve, one of Musk’s most ardent fans posted on Twitter that drivers with more than 10,000 miles of “Full Self-Driving” testing should have the option to turn off the “steering wheel nag,” an alert that tells drivers to keep hands on the wheel.

Musk replied: “Agreed, update coming in Jan.”

It’s not clear from the tweets exactly what Tesla will do. But disabling a driver monitoring system on any vehicle that automates speed and steering would pose a danger to other drivers on the road, said Jake Fisher, senior director of auto testing for Consumer Reports.

“Using FSD beta, you’re kind of...
