I once spent two hours in a U-Haul that might not have had any suspension at all dodging potholes on a poorly-maintained stretch of highway, during which I learned why people call them "the turbulence of roads."
I actually just made that up, but I think it could really catch on.
The worst part is that fixing a pothole isn't exactly an overwhelming undertaking -- it doesn't take a team of civil engineers to pour a bunch of asphalt into a hole until it's not a hole anymore.
It's a simple task, which is exactly the kind of project most municipalities are terrible at completing efficiently.
As a result, potholes have a tendency to pile up, and there's normally not much incentive to fix them.
However, one spray-painting vigilante -- dubbed "Wanksy" for reasons you should understand -- is encouraging the English town of Bury to fix its pothole problem by drawing penises around them.
