It could have been handy when I was attacked after a hit and run to my car, the numbers of the km distance on the motorway were not available, that's about the only time I can think of where I could not get across my location to the emergency services, it actually took another passer-by to call the police and tell them I was getting beat up before they responded.
The control room where I was calling kept asking for the km pole number and as I was under a bridge at the time there was no km pole around, I wonder if they would have responded to scoots.flock.pushed
