I’m not sure point to the UK is a good example. There are plenty of weird and obscure laws that simply aren’t enforced or followed anymore. Everything from laws about handling salmon suspiciously, through to various right around who can drive sheep across Tower Bridge.
Those laws survive not because anyone considers them a good idea, but simply because the issues caused by ignoring them are substantially smaller than the effort involved in removing them.
We also have a bunch of laws that are still followed, but only in the most technical sense. Every “Parliament route” train schedule falls into that category. Train services that must be provided at least once a day, sometimes only once a week, which nobody actually uses, and in some cases only travel to stations with no practical public entrances. Those laws don’t survive because anyone things they’re a good idea, it’s just easier to run the train, than it is to get parliament time to abolish the law.
