Speed bumps

Speed bumps. Lots of speed bumps. Everywhere. The best is when you find speed bumps on UNpaved roads - roads that might pop your tires. Roads that are most certainly are not designed for speed, but apparently ARE designed for speed bumps. I wonder if people think that there is actually a necessity for the speed bumps on the unpaved roads? Or are they just jealous of those people living on the paved roads - and add the speed bumps just to make their street more like them? Then maybe no one would notice their street was unpaved?
