The main problem is the sheer weight of commercial vehicles being crammed onto roads never intended for them.
We are unfortunate enough to share a postcode with a large educational establishment which is 100m behind us on the main road. Of course every delivery vehicle uses sat nav, so gets half way down our (clearly signed) cul de sac before it occurs to them they *might* have taken a wrong turning.
We don't live in a road, so much as an open cast mine. I managed to get some holes fixed when I wrote to the council asking who could keep the money from any diamonds that got thrown up ;)
