Don't think this beats anything, simply a habit.
Recite the numbers on the signposts that indicate how many kilometers we've traveled and then convert them to miles.
Then the numbers on the exits for places passed, counting them down until I reach my exit. I also recite aloud the names of businesses along the way.
One of my favourites is a place that manufactures recreation vehicles, some of the rv's are called safari condo's.
My Father, did the exact same thing.
I read license plates... add up numbers, make acronyms from the letters (sick mind) : )
Some are just way too easy
