On German highways there are often speed limit changes from unlimited to 130km/h or less. So if I drive for example 200km/h and see the speed limit sign and i go completly off throttle and my car reduces speed to about 180km/h until i reach the sign. So I have to break fast from 180 to 130km/h or less. This is big wear for my brake pads. To get a longer lifetime of my brakes and to get a smoother driving I wish to get a message 1 or to 2km before the speed sign (only on highways when speed changes from unlimited to anything), maybe same style as for any other hazards. If i see the message I could put my foot off the throttle and could roll until the sign (saving fuel). As Waze knows the speed limits and high ways I think that's easy to programm. For not to annoy people who don't need it an option to switch it on and off in the settings would be nice.
