Additionally, one person's 5 star is another's 3 star. It should be the deviation from your typical ratings. If I give everyone 3s and I give someone a 2, that's less significant than if I regularly give everyone 5s and I give the person a 2. The second person likely messed up way more. Moreover, they will ask you for the rating several days later if you don't take frequent rides and open the app again. Unless it was terrible, I probably don't remember the details.
