I think that Waze is a great comparison. There's an app which is explicitly used to find and avoid police in order to flaut the law.
The main difference in my view is that Waze is individual people doing this, which we approve of, conversely Uber is a corporation many dislike. In situations like this it's important to acknowledge bias and try to abstract to the general case and reason about that.
Waze users are following the law when they get near Police officers. Uber users are continuing illegal behavior but obstructing police visibility. Uber's behavior is more like radar jamming or putting up a barrier in front of police.
