Sure, and it could be the only way he has to make a living. He might also be a thug out for a score. More good reasons for CC.
What is CC?
Uber drivers are screened well. “Thug out for a score”? not after rigorous evaluation, paying for the expensive new car (and ongoing high-end maintenance), and making a good buck just shuttling people around. If you’re going to put that much effort into getting _into_ that position, you’re NOT going to just throw it away “for a score”.
Like most “why would you carry at location X?” questions, it’s not that you need CC for the location, it’s the trip to & from. Standing on a street corner poking at the Uber app to call the car on your smartphone tells a thug you’ve got money.
