Many people still use Waze for getting live traffic updates on a roadtrip (object on road, police speed trap ahead). I don't think those features were fully incorporated into Maps.

Once I showed my father-in-law the "police reported ahead" and "hazard reported ahead" features he was sold. He now demands Waze on every road trip and he's not especially tech-savvy. Google doesn't supply this same data.
I can confirm that it is 100% not the case on iOS. There is not a way to report these things on the CarPlay app at all, and only very occasionally will there be a "speed trap" alert on Google Maps.
That's exclusively a "not implemented in CarPlay" thing, the feature is very obviously supported in iOS; it even has its own "bubble" in the main UX while navigating.
It's crowdsourced, so it depends on another Waze user having spotted them and put a report in the app, so the usefulness his highly dependent on how many other Waze users are in the area.
