But enforced by different authorities, I think. Council can enforce the yellow lines, the Police the mandatory lane, hence the duplication.
FWIW, I do see the parking enforcement people at that end of town fairly frequently (at least, more frequently than I see them anywhere else). The big problem is that the drivers doing this are selfish, and evidently don't give a toss about the possibility of getting a fine.
Quite. In Epsom, the council, in their wisdom, have decided to allow blue disabled badge holders to park on double yellows.
Now, I'm all in favour of disabled people having enough spaces to park in, and in places convenient for shops &c.
But either a location is a safe and appropriate place to park or it isn't. If there are not enough disabled spaces, they should create more in existing car parks, by converting some of the ordinary spaces to disabled ones.
Having this odd system where parking on a double yellow is OK if you have a blue badge is just ridiculous.
