Drivers also rate you as a passenger. If they rated you 1-2 stars, you would never get picked up again. By doing what you're doing, you're making your drivers less likely to keep their jobs, just because they landed on some OCD individual who thinks (s)he's capable of restoring the average rating to 2.5. Uber and Lyft drivers need to keep their ratings in the 4.3-4.7 area in order to keep working, so please stop doing that.

Also: end up, they're, response, rating, thing

The whole reliance on fixed points on a 5-point rating scales either assumes that users share a common culture, or is blind to cultural differences in how ratings are applied which are well-known.

Anyone who does that is doing something so stupid that it should be undermined.

That's a tricky approach for an international organization like uber to rely on, as the cultural attitudes toward tipping vary.
