Mike Isaac’s Super Pumped (p. 234) describes Uber leaders’ disdain for drivers. As managers examined comments from drivers, “one manager expressed disgust with the spelling and grammatical errors the drivers included in their responses. ‘God, I can’t believe these people’s votes count the same as ours,” he quipped to his subordinates.”
Isaac also points out the high churn of drivers — how quickly drivers stop driving and don’t return. As of early 2016, roughly a quarter of Uber’s drivers churned every three months — requiring the company to constantly seek other drivers.
