@lanodan @alyx you mean the wheel lugs? at least in the US there was way too much of a problem (this was something like 30 years ago) with tires being stolen from parked cars. at least the ones I saw would have a single lug nut that couldn't be removed with a standard socket and the tool for it would actually come with the car as part of the spare tire kit or you could always buy one from the dealer
none of the recent cars I've done work on have had this. not sure when it fell out of favor
I'm not sure how effective a deterrent it was in practice since realistically a huge range of car models would use the exact same one. I guess it made the theft a bit more complicated though
it's like those "security" screw heads that you can buy the full range of weird drivers for at the hardware store in a single kit so what was the fucking point?
