Kate parked the car,and later told police that the man snapped open his seatbelt,grabbed her on the neck and arm,and pulled her towards him for a kiss.
He continued to grip her while she screamed and asked him to stop,she said. Eventually,he stormed off,saying"your loss,baby".
Ms Miller has since suffered panic attacks,she has had trouble sleeping,and took days off work to recover.
"I felt completely violated,I felt like my safety had been put at risk and I was too scared to work,"she said.
"Whenever a guy sits in the front seat I lean over to the door,I'm aware of what he's doing and where his hands are,what he's saying,it's just made me second guess everything.”
Ms Miller says she is risking her job to tell her story to the media. She wants to shine a light on the safety of drivers - and particularly women - at the popular ride-share company.
The man was put on a diversion program and ordered to write Ms Miller a letter of apology,but she isn't satisfied.
