I think the sign is really funny, what makes it even funnier is that it's very close to a prison, which I guess is why they've put a ball and chain on it. The road traffic department says they're not going to press charges. Luckily they have a sense of humour, occasionally. Personally I think they should just leave it like that, but that's against regulation.
I think one of the reasons they're not pressing charges just because they're in the process of changing the signs anyway.
I don't like the new signs, it's just stick figures. They're supposed to be gender neutral, but just to be difficult I don't think they are: the stick figures are all men. They're all wearing trousers and hasn't got any breasts. I think the old signs were a lot nicer, and: there were both man and women featured on them.
Here are the old and the new signs, which ones do you prefer?
Another reason why they're changing the signs is so that they will be easier to read, and because they want them to be more like the rest of Europe. I think it's just charming that they're different, as long as they're understandable I don't see the problem.
