IRVINE, Calif. (KABC) -- A once loyal Lyft customer is now fighting the ride-sharing company in court, claiming the company did nothing to prevent her from being sexually assaulted by a driver.An Irvine mother - who only wants to be identified as Natasha - said it's now traumatizing to even be a passenger in a car."Even if I'm in a car, I have to avoid that side just because I have that feeling of what happened in that moment. I was just terrified," said Natasha.She was taking a Lyft ride home in December 2018 when she was sexually assaulted by her driver Mario Cario Rojas, according to the complaint she filed in Orange County against Rojas and the ride-sharing company."Right when we got on the freeway, I tilted my head back and closed my eyes for a bit. It was late. I just woke up and he was groping me. I was stuck in a situation where I didn't know what to do. It's 3:00 in the morning, this guy is doing this, I'm not at home."It's difficult for Natasha to put into words how she feels and recounting that night is even harder."I was screaming, "STOP! No! What are you doing?!"Her pain was amplified after the Orange County District Attorney's Office declined to press charges against Rojas citing insufficient evidence."A lot of women, I feel, who haven't gone through that experience, or people in general, don't really understand what that feels like when it doesn't happen to you."Her attorney Gregory Bentley said Lyft did little to protect his client from the alleged assault, and the trauma that followed, alleging in the complaint Lyft should've known about Rojas' prior legal problems."This particular driver had a DUI in 2005, he pled guilty to driving with no license in 2015. He gets hired by Lyft in 2017. Lyft had no continuous background check program in place after they hired him. If they would've they would've realized that, just a few months after he was hired in October, a temporary restraining order was issued by a judge in Orange County by his wife and three kids for physical abuse."Lyft gave Eyewitness News this statement:But Bentley said Lyft has only recently changed their policies and they haven't assisted police in this particular case. He wants the company to be held accountable."Lyft, in their response, doesn't cooperate with the police department, doesn't speak with the police, doesn't give them documentation," he said.As for the driver, Bentley said they're still fighting to put Rojas behind bars. Bentley has sent the Orange County DA more information, because he said Rojas needs to be held criminally responsible and Lyft should be held civilly responsible.Attempts to reach Rojas for comment were unsuccessful.Natasha just wants to make sure this doesn't happen to anyone else."It's changed everything for me," she said.
