I found this Reader’s Digest article via Active Response Training. I’ve only recently started using ride sharing services, so I took a look.
Most of the scams are drivers asking for cash to double dip the fare. The biggest takeaway from this was if you’re paying through the app, and the driver demands cash, report him/her to the company. I would also recommend that you listen to your intuition. If something seems off, end the ride or don’t get into the car.
