"New York brought in a new system where #Uber drivers are effectively guaranteed $15 an hour after costs. The idea is that for every hour the driver is logged on to the system, Uber has to top up the driver’s pay if they don’t reach the threshold through fares. What it means is that Uber no longer has any incentive to oversupply the platform with drivers."
