 YouTube is updating its eraser tool to remove copyrighted music while leaving other audio intact. The tool allows creators to easily remove music they didn't pay for without affecting dialogue or sound effects. And a Phoenix police officer pulled over a robo-taxi for driving on the wrong side of the road. The now-viral body cam video shows the officer's shock when he walks up to the car to see an empty driver's seat. The autonomous vehicle belongs to San Francisco-based Waymo, which recently recalled nearly 700 vehicles because they couldn't recognize poles.
