Rape accusations, true or not, always end destroying the accused, specially because there are low penalties for false accusations, and the media is very fast in plastering the person name and photo everywhere.
Also, being a driver is kinda dangerous regarding that, I have some driver friends, and they all have the same rule: They don't pick up lone women, period, it might be raining, hurricane, dust storm, middle of the night, day, whatever, if she is a woman, and alone, they don't pick up them, ever.
It is because here in Brazil at least, is a very common scam to a women accuse a driver (be him professional, like a cabbie or Uber-like driver, or a volunteer that wants to help a hitchhiker) of rape, or make threats to accuse him unless he pays her something.
On this case in particular, I think the best is wait for what a judge and evidence has to say.
