I'm thinking Uber might be able to create a better driver quality score using meaningful user inputs rather than ratings. For example, after a ride, it could give the user the option to prefer the same driver in the future if available, or even to wait up to X minutes extra for this same driver (or something along those lines). The percentage of users who choose these options would be a very clear signal of driver quality, and would be less likely to be gamed because the user has a clear motivation to answer truthfully. I expect there's other info that could be used to calculate the score as well. Average tips compared to other drivers in the area comes to mind, although that could have negative consequences (mainly increased pressure to tip). Perhaps if it were combined with other inputs though. I'm sure there are other options too.
