Waze, owned by Google, does this by asking other drivers to confirm reports on the ground. I don't recall Google Maps doing this.

Google Maps does this in the US. But I've heard that it has different features in different places.

Android auto has incorporated this 'feature' in maps.

I get the feeling these two systems don't talk at all.

I've used GMaps for navigation while on vacation in remote areas and the routing will be completely different than Waze, even when settings are made identical when it comes to time-vs-distance, avoid tolls, etc. Waze is much, much better.

I use maps from android auto. I have never had Waze. I get requests on my screen to confirm an obstacle, a traffic jam or a police speed check is still there. I'm not claiming it is shared code, just shsred 'features'.
