There's a suggestion on Twitter that Google ignores what the council has told them and uses driver behaviour to gauge whether a road is really open or not.
Given it also sends drivers that way and many will trust their phone over silly road signs, there's a long cycle before it gives in and considers the road closed.
I believe it's camera enforced, as it's part time and buses are allowed through.
Is it enforced by a camera? One on my road is enforced by camera and it took a few weeks for people to stop just driving straight through (I think once google maps updated)
