Note that this is a variation of stack ranking, which has incentives for the usual sorts of manipulation like avoiding "difficult" times like rush hour.

One could say that a "rush hour ride" is a different service than a ride at a less crowded time.

Hotels in a small town might have better reviews than hotels in New York. But if you want to stay in NY, you compare between the hotels there. So the hotels in the small town do not have a benefit of their "manipulation" to offer rooms in a less crowded city.
