You're missing out on the speed trap alerts, though. That's the primary reason I use Waze over anything else.
Speed trap notification are for more than just evading law enforcement. It lets you know that there's going to be a slow down because a lot of people who see cops instinctively tap the break and that has a domino effect. So if you're coming up the hill and you don't see the traffic yet, you can still be prepared.
No need to get on a soapbox.
What would be amazing is if the major apps opened the social aspects to share this data.
