As someone who also enjoys the hills, its a good thing that vehicle access isn't permitted under RtR. After seeing first hand the atrocious state spots are, and have been left in through dirty camping, car based predominantly, because they cant be arsed or unable to carry all the cheap Aldi/argos/sports direct shite and the kitchen sink they have to take, its always a minority that ruin it for others. Habitats that take long time to develop, SSSIs, ground nesting birds would be at increased risk. The flecking idiots tried hacking chunks off trees to burn their beer cans. Would only take a member of the banger disco crew or some scrote to "explore" off a track to piss off the land owners. Won't be long though before there is a train, lift, engineering solution to get lazy or unable to the top of every peak because they feel they should be able to experience the same as everyone else.
