How often does this happen?

I am gonna guess it happens every time a car is driven one mile past 111,110 miles. What does this have to do with pharmacy?

No, actually, it doesn't happen every time a car is driven one mile past 111,110 miles.

It happens every time when, at 109,999.9 miles, you reset your trip meter. At 111,111 miles, your trip meter would read 111.1 👍
