Have one main button on the navigation map screen that when pressed dynamically separates into 6 buttons (3 on the left [upper corner, midlevel, lower corner], 3 on the right). This would cut down on the clutter when an update is not needed.

Allow the user to customize these buttons to their most commonly used ones. For me, they would be car on the shoulder, heavy traffic, and hidden cop. If the update was on my side of the road, I would customize these to the right 3 buttons. If they were on the opposite side, I could customize these to the left 3 buttons allowing for some laterality of sorts.

Once one of the six buttons are pressed, the update would be entered immediately without an option to save it for later.

The suggestion allows to user to quickly update map information in a shorter amount of time due to familiarity and less button pressing. This will ultimately shorten the time the user's eyes are off the road and improve the safety level of using this great app.
