Obstruction of justice and interfering with police duties are crimes in plenty of jurisdictions. I'm not sure Waze is a good comparison - your behavior around knowing where a police car was sighted is to comply better with the law, so it'd be hard to argue it's obstruction of justice.

It may be...it may also be to avoid the area, for illegitimate (I'm a criminal police are looking for) or legitimate (the local PD is notoriously racist against people of my race, and I want to avoid being hassled) reasons.
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.
