This girl is damn lucky she didn't get raped or worse. OP said she was sweet and the driver zeroed in on this thinking she was weak and completely dominated her in the car. Give her credit, she made some very good decisions under a lot of pressure. She thought on her feet very well.
The company may be choosing the lesser of two evils here. If they get sued for the info or are forced to turn it over by a warrant, they can live with that. But if they get sued by the driver, that could be a lot of cash. Doubtful if they ever use this driver again. Certainly his account was flagged after this.
