Parts of Germany, lots of Poland, Austria, etc. South Europe where I'm from is "decoration land", but the more east you go the harsher they are/were with enforcement so the more people abide.
In countries where open police corruption is more routine, cops love enforcing such laws because it's a very low-effort to extort bribes. Not even because the fine is significant, but because the procedure to pay it once given a ticket may be rather onerous compared to just handing over a banknote and going on your way.
