I10 111.2 MM
West of Phoenix on I10 there are several miles of MMs like 111.2, 111.4, etc. What is that all about?

Having the markers at .2 mile marks helps emergency services find you, particularly if they are comming from the opposite direction. They know where they have to cross the median to get to you. Police, Fire, Rescue and tow truck drivers know the markers in their service areas even if AAA doesn't even know which country you are in.
