In one recent TV commercial, a smiling actor playing a sometimes-driver quips, “These days, everyone needs a side hustle, and driving with Uber lets you go from earning to working to chilling at the push of a button.” The sound of a cash register chimes in the background.
What Uber has never said publicly is that half of the driving gets done by people who work more than 35 hours a week. Those workers generate about half of Uber’s revenue and are responsible for about half of Uber’s trips, Uber confirmed after Bloomberg analyzed a study of its drivers conducted by the company. A small number of those drivers will go to extremes, like sleeping in parking lots, to make a living."

Note - its possible for both 60% of the drivers to work less than 10 hours a week, and for more than half the driving to be done by people who work over 35 hours a week.
