I believe you're missing quiet a few Zeros at the end of your number. $3,800 probably won't even cause a patch truck to leave the yard, only someone thinking about doing work. I would say #1 cause for road deterioration is road salt. The constant freezing and thawing of the road, which is what salt promotes, causes the cracks, chunks and anything else to break apart from the roadway.State of Minnesota after some odd 40 years of this BS did a study to learn that one ton of salt is costing 3,800 bucks in road damage besides rusting out our bridges. Not even mentioning causing us consumers billions of dollars with vehicle rust out. Brakes are the first thing to go with this dam salt.
