Waze should have the option of Current Speed Limit Announcer, everytime when the speed changes, or if your on the road, and the speedometer pops up for example, “35” in a 35 mph road, or “60” in a 60 mph road

Waze on your phone and/or CarPlay should speak “The speed limit is “35 mph” or “The speed limit is 60 mph”

It is a lot better than looking at your radio just to see the speed limit is posted to prevent a crash
