The Uber drivers forced to sleep in parking lots to make a decent living

A growing group who commute from places as far as eight hours away spend the night in their cars to pick up fares around San Francisco during the day

Every Saturday morning before the sun rises, 35-year-old Uber driver Sultan Arifi rolls up the sleeping bag in the front seat of his car, places it in the trunk, and prepares for another day of work.

He will spend the next 12 hours picking up as many passengers as he can on the streets of San Francisco before returning to a grocery store parking lot in the north of the city to sleep, often for six hours or less, rising as early as he can on Sunday to do it all again.
