Once I was paying close attention to my TomTom with it's nagging about "stay in the right-most lane" etc,
I had not yet mounted it my dashboard (it would block the view). Well, thqat must be better than "lookin g down ", because a cop pulled over for "weaving". When he saw my TomTom NOT glued to the dashboard, he scolded me (and I have to agree).
If you look down at the little digital nagging box, you might swerve out of your lane, or in to a lake.
But it reminds me of someone's explanation : "I'm not nagging, I'm RIGHT!".
I also shared a cube briefly with a co-worker who posted a printed warning:
"I'm not bossy, you just need to be told what to do."
