Potholes can be a great nuisance when driving/riding a vehicle, that's obvious to anyone that has experienced them. Apart from bringing discomfort, they increase noise and lead to increased
wear on the vehicles, especially the tires, with high maintenance costs as a result. Broken tires mean pollution.
Occurrance of potholes can also lead to dangerous accidents when cars get out of control, either trying to avoid the potholes, or after running into them
with a possible flat tire as result.
