As with any measured system, people will always try and game it for their own goals. The first article I found is from 10 months ago: http://www.sfchronicle.com/business/article/Uber-incentives-aim-to-lure-power-drivers-7089842.php http://www.sfchronicle.com/business/article/Uber-incentives-... "In one offer, Uber is now guaranteeing $2,000 a week in gross earnings for new drivers who work 60 hours a week. Another, more-extensive program for existing drivers promises bonuses based on how many trips they complete. For 100 trips in a week, they get an extra $350, for instance." If a driver can already easily meet those then great. But it wouldn't be that great to spread yourself amongst the services and avoid the incentives. And remember the larger incumbents have more wiggle room in terms of incentives and changing them based on real world driver behaviour.
