Road closure automatic pop-up
It would be nice, when we don't follow Waze instructions, that Waze automatically show a little pop-up to ask why we didn't follow the instruction. It would have, for example, 3 buttons: roadwork, closure, ignore. And if the user doesn't do anything after 10 seconds, the pop-up would just ignore and close.
It happened multiple time to me that a road is closed, but because of circulation around and behind me, I can't really take the time to navigate in the UI to find the good option to signal it, and then, once I have the time, it's just too late. While, with a pop-up, it would be really straight forward.
We can also imagine a double pop-up, the second one used as a confirmation, to prevent user input error.
