They get paid.

Wait, so this is just Uber where after you finish your short Uber shift, you go to work?

Sorta. Unlike a normal Uber driver, the carpool driver (1) specify their rough route, (2) can decline riders without penalty, and (3) isn't paid as much (basically enough to cover gas, I think). But yes, the pick-up/drop-off interface was supposed to be more or less the same.

Ah, thanks. I probably should have looked all of that up.

Uber doesn't let you put in a destination as a driver.
