Tesla has recalled more than 360,000 electric vehicles over the risks posed by their self-driving software. The recall follows several high-profile accidents, including an eight-car pileup on the San Francisco Bay Bridge last November, triggered when a self-driving Tesla Model S abruptly changed lanes and rapidly applied its brakes. Nine people were injured, including a 2-year-old child. On Thursday, Democratic Senator Ed Markey tweeted that Tesla’s recall is long overdue, adding, “We have been sounding the alarm on the critical flaws in Tesla’s software and its misleading advertising for years. The National Highway Transportation Safety Administration must continue to protect the public against these safety risks, and Tesla must stop overstating the capabilities of its vehicles.”

Meanwhile, Tesla workers at a factory in Buffalo, New York, have filed a complaint with the National Labor Relations Board, saying Tesla managers fired more than 30 people this week after they announced their intention to form what would be the company’s first U.S.-based labor union.
