You’ll also have the option to use customer feedback, if you think that makes sense.
Take a look at Lyft’s post-ride survey. Rate your ride, plus a set of chips that let people express what stood out about the driver, plus a comment field. Very simple & quick to complete.
Right now, the system works on a black and white "I was satisfied with this answer"/"I wasn't satisfied with this answer". If too many users note that they were continually unsatisfied with a particular answerer's answers, then I'm planning on handling that issue myself.
