TBH, this is a pet hate of mine. I see people parking on grass verges all the time, and they don't give a shite about the damage they do to the verge that either the council have to pay up to maintain or fix or the home owner has to come out and try fix it.

People drive onto them in the rain, dig up half the bloody grass and leave mud trails down the road and in fairness it looks crap afterwards.

Sounds like you got an inspector with the same pet hate out for a walk
