Well let me be a bit argumentative here for a second. Are you saying that with every other vehicle you have even driven, you never regularly looked to check you speed? How would that be any different than checking the screen to watch for the nags? Just normal city driving you are being distracted by way more than a simple nag notification while on a highway. Paying attention to every road sign to make sure you are doing what you are supposed to be doing in the area you are in, or not going into an area you shouldn't(one way, do not enter), watching for lights turning yellow/red, pedestrians...etc...all of which are taking your eyes off the road directly in front of you.
