Also, Uber actively discourages this by penalizing drivers who skip to many fares, which suggests they really don't want you to do this.
At some point, Uber promised to pay a minimal hourly wage so if there were no passengers requesting rides, drivers would still make (a bit of) money. The resulting scam was to sign in as a driver, then just sit on your couch, skipping fares while still making a non-zero amount of money.

This is more like an employee working at a call center, and answering calls for another call center on their cell phone instead of taking the ones that are ringing at their desk.
