Do drivers really rate passengers? What happens when my ratings are low?
The Guru Take
Yes! Drivers rate all passengers on a scale of 1 to 5 after each and every ride. Drivers actually have to maintain a 4.6 star rating on the platform to stay active with Uber and Lyft so a 4 star rating is a failing grade for a driver. But there's actually no such requirement for passengers - the lowest rated passenger I've ever seen had a 2.0 star rating :)
Most passengers are in the 4.6-5.0 range though and even if you're on the lower end, you probably won't ever realize it. Some drivers will filter out the lower rated passengers during busy times but for the most part, drivers are just happy to get a ride. Here's a good guide on how to maintain a high passenger rating - in short though, just treat your driver and their vehicle with respect.
Drivers must rate their passengers.
Yes, drivers to rate passengers, and due to the way the app is set up, the driver must leave a star rating for each passenger that just completed a trip.
What happens to passengers who have low ratings? Rideshare companies do monitor this, and when they identify problem customers, they can send out warnings, deactivate the account, etc. Some drivers say that riders with low ratings are matched up with drivers with low ratings, but that has not been verified yet.
UPDATE (09/2018): Uber has started to penalized passengers with temporary suspension for having low ratings.
