Running over pot holes can be a serious hazard. They are not visible at night and sometimes are quite deep. There have been instances of tires actually popping because of them! The wheel of the tire can actually bend and pop the seal, not only causing a flat tires, but the need to replace the entire wheel.
People are fed up. There are taxes taken from citizens pay which are supposed to be allotted toward the maintenance of the roads. Knowing the hazards and the lack of keeping up with the deterioration, people are opting to purchase and plant deterrents for drivers who otherwise may have to spend money to fix their vehicles.
All the while, they are beautiful and may just bring a smile to ones lips rather than cursing.
