Or, a customer service flaw that disincentives use of Uber's service due to the unreliability of their contractors could be addressed by Uber, as a cost to those unreliable contractors, as I suggested. What part of my post (or any other posts I've made on this topic, for that matter) suggests I feel government legislation would be appropriate here?

EDIT: Furthermore, this is already something Uber does with their star rating system. This would just be a logical extension of that.
