1. When driver's are about to log off, it tells them that they are very close to reaching an earnings target, such as "You are $6 away from making $40 net earnings". The target is set by Uber, and is always just out of reach.
2. Uber suggests to drivers that they should go to a certain area for better chance of finding riders. The article says this might be an example of where Uber benefits at the expense of drivers because Uber does not prefer surge pricing.
3. Uber prompts drivers to accept the next fare opportunity before the current ride is over.
4. Uber tells new drivers when they are 50% towards the goal of 25 first rides. At 25 rides Uber will pay a 'signing on' bonus.
5. Some Uber employee's would pretend to be women when communicating with the (overwhelmingly male) drivers.
6. Lyft did a split test of two different calls to action: (a) "You're losing $15 per hour by driving on Tuesday mornings instead of Friday evenings"; and (b) "You would make $15 per hour more by driving on Friday evenings instead of Tuesday mornings". They found that (a) was more effective, but eventually decided not to use this approach [for reasons not explained in the article]
7. Uber provides non-cash rewards to drivers in the form of 'badges' like "Above and Beyond", "Excellent Service" and "Entertaining Drive". It also gives drivers stats like how many trips they have taken in the current week, how much money they have made, how much time they have spent logged on and what their overall rating from passengers is.
