Jul 28, Ma,ekaih Sep 13, Sep 14, Hi, Ma,ekaih! Andrew Dec 18, We broke down recently on in Massachusetts. We were literally 10 feet from a mile marker to the 10ths place something like Thought we'd have no problem with road side assistance determining our location. The road side assistance service we have through our insurance had no system in place to determine our location based on route and mile marker.

And MA doesn't do their exit numbers by mileage which is genius! Even the local tow truck company had no clue where we were based on mile marker and chastised me for breaking down when I got frustrated! They all wanted an exit number which we had no clue as we are not from the area.

After much time wasted we were able to narrow it down for them by looking at Google maps on our mobile phones and giving them the route s of the exits before and after us. Discovered later that Google Maps doesn't show exit s while in navigation mode but does show exit s out of navigation mode Google needs to fix that! It was a very frustrating and unsafe experience.
