Lots of UK motorways have variable speed limits. Obviously these change a lot so there’s no way we can have a live map of them, but as you go on to a road with a variable speed limit it would be nice to get a notification saying something like “Entering Variable Speed Limit Area. The legal speed limit may be different to the limit shown in Waze.” Another useful notification could be on the approach to traffic or around reported broken down cars, a notification asking the lines of “Hazard/Traffic reported on the road ahead, pay attention to Variable Speed Limit Displays”. All these alerts should have the ability to be turned on and off by the user.
