The lead singer of the rock band Modest Mouse — who once sang in a hit song that “I backed my car into a cop car the other day” — was sued Wednesday for crashing into a pickup truck in August 2016. But unlike the driver in the band’s mega-hit “Float On,” the Portland, Ore., city employee involved in the crash didn’t “just drive off.” Instead, she’s suing 42-year-old Isaac Brock for nearly $1 million. City employee Cassidy Kane, 41, claims the crash caused herniated disks in her spine and did other tissue and muscle damage that continues to cause her pain and numbness in her extremities.
