Failure to Stop

I did something unusual yesterday (not something unusual for me, but unusual for someone living in Greenville). I was driving along when an ambulance came up behind me with lights flashing and sirens blaring, and I pulled over to the side of the road to let him go by! That may not seem unusual, but I was on a busy, two-lane road, and not one other car ahead of me or coming towards me did the same! The cars on the other side of the road kept driving at normal speeds, and the cars ahead of me simply sped up!
