Those mile roads often have odd names like "18 Mile Road" or "12 Mile Road", so even after a transition it wouldn't be especially hard to track (I'm guessing you are subconsciously tracking the numbers, not measuring on your odometer...).
The survey system is a bigger thing to deal with, but it isn't something people confront day to day either. I've seen deeds using geographic coordinates to describe plots, so there is also a relatively straightforward path to not dealing with it.
