Mike Isaac’s Super Pumped (p. 265) describes perils in Uber’s Xchange program, in which Uber provided vehicles to high-risk driver with poor or nonexistent credit.

Two, dealerships were pushing these drivers into expensive leases that lowered profits for both drivers and Uber — causing Uber to lose more than $9,000 per vehicle. Furthermore vehicles were returned in far worse condition than anticipated.
