It's all very nice if things go your way, but if it's public property, be it a residential road, a trunk road, a beach or whatever, it belongs to everybody and everybody has an equal right to use it.
Of course they have the right to be there and drive there etc, but what people DON'T have the right to do is just dump their cars (illegally) in passing places or at the side of narrow country lanes and disappear for the day @WeBuiltThisBuffetOnSausageRoll
It never happens during the off-season. People see a full car park and instead of turning around and going elsewhere, they just dump their cars wherever they fancy. It's like they think they've got the right to park there because they've made the journey.
See this from last weekend:
www.lancs.live/news/local-news/police-plea-avoid-wasdale-head-20708838
"Officers report that a crash at Wasdale Head is causing major delays and the road is blocked - with emergency services unable to gain full access to the area due to inconsiderate parking.
Cumbria Police say that National Trust wardens are reporting that all the car parks in the area are full - and they are asking people to avoid the area as there is "nowhere safe to park".
Yes, of course people have the right to visit the area but parking in a way that blocks emergency access is inconsiderate and lazy at best, selfish and life-threatening at worst. And it happens every single BH weekend, school holiday and nice weather day.
It's not surprising that people get pissed off.
