When I choose to drive outside of highway on waze, the app keep notifying me A LOT for "going faster by going on the highway". But I choose to NOT drive on highway, its not to have a pop-up for it every 10 minutes. It is very annoying, the highway doesn't have the same cost depending on your country and vehicle, and when you choose an option, you souldn't have a pop-up asking you every 10 min if you want something else.
