If it is broke, fix it. If it ain't broke, leave it alone!
But you need a reliable process to see if it's broke.
I think you're driving too many miles and affecting the roads adversely. We'll need you to log your miles daily from here on out. Just to see if there's a problem. We're not aware of any problems yet, but we can't be certain.
After all, roads are a public resource and we need to manage them well. I'm sure you'll understand, being a good citizen and all. Thank you for your data.
