Do we really know where potholes are though, I would think not. I mean when you drive over it you know, hey pothole here, and probably people know hey this stretch of road is badly maintained but unless you have an accurate map of where each pothole is then it follows what you do is to select a stretch of road and say we will go down this stretch and fix it this month.

Which would seem inefficient if you had a cheap way of amassing exact data on where precisely all the potholes actually are.
