Tesla (TSLA.O)  opens new tab and its CEO Elon Musk on Monday won the dismissal of a lawsuit accusing them of defrauding shareholders by overstating the effectiveness and safety of the automaker's self-driving technology in order to boost its stock price.

U.S. District Judge Araceli Martinez-Olguin in San Francisco said shareholders failed to show Tesla and Musk should be liable for falsely promising they were close to delivering technology that would drive safer than humans, but that was actually "plagued with safety issues" and encouraged inattentiveness.
