@QasimRashid Sad that it's needed, but this seems a great idea.
My only concern, and it's maybe something addressed already somewhere, is the potential risk of people being pulled over, trying to reach for their phone to open the app, and that physical movement itself being misinterpreted as them going for a weapon, thus accidentally escalating the situation.
Not sure if that's something that would need to be considered in the on-boarding process the first time the app is run?
