Masturbating passenger

My friend, 28F, is a Lyft driver. I just saw her yesterday and told her that I worry for her safety.

Less than 12 hours later, she started driving this morning and a male passenger began masturbating in her back seat at 07:30AM. She was in utter shock and disgust and didn’t know what to do, as she felt her safety was clearly at risk. She felt like completing the ride was the safest option.

She reported it to Lyft and all they said to her is that they are sorry this happened to her. Told her because she has “no evidence”, they are taking no action and a reminder that she can cancel mid-ride if she feels unsafe. Nice.

I told her to file a police report and she needs a dash camera.

The only information she has is his first name, race, that supposedly is in military, and pick up/drop off locations.

Does anyone have any other advice as to how to help her? Is Lyft seriously taking the side of a passenger that has a serious accusation and that she has to just accept it?
