Hot take: I dont care if others think 5.0 is acceptable while 4.8 is disastrous. I’ll rate 1-5 on a scale normalized at 3.0 and meaning ”meets expectations”. Luckily scores in Europe seem to be much less lopsided than in the US so giving 3’s and 4’s probably doesn’t leave someone without food on the table.
Really they should just stop having number scores and have ok/not ok and anyone with a significant number of not ok shouldn’t get any more business. Beyond that they already have a metric: driver tips.
Doesn't this mean that rating scores end up measuring the distribution of what customers believe "decent service" corresponds to, rather than the performance of the driver? And in this case, whether a driver ends up with a score above or below their peers will just reflect which customers they were fortunate or unfortunate enough to have.
