I don't smoke, but my late mother did. I was really very surprised stopping and seeing there is no smoking anywhere at the rest area. I mean, it's outside. They could at least designate a smoking area like they have in airports (but outdoors). I don't allow smoking in my vehicles so in addition to stopping for the biological necessities it was good to allow her to get a smoke in.
She's gone now, but still, it seemed overly restrictive to me.
Also, have had stupid Garmin instructions. In fact just Tuesday I was in Moline and instead of sending me due east to get on I-74 at 23rd Ave it wanted to send me south to John Deere road then get on 74 to go north.
Also, I like the real maps/atlases to plan some trips. A lot of times I prefer to take the 'road less traveled by' - such as county roads etc. I get bored driving the same crowded interstates. Unless I am in a particular hurry.
