I asked my father - a lawyer in Spain - about these kind of terms, and he explained to me that the vast majority of noticeboards that claim no liability are total BS (at least in Spain, and talking about the kind that are on a wall, not signed/agreed ones). I still think it's highly relevant for this case; a contract implies agreement AND benefits for both parties, so if you cannot legally avoid agreeing to this contract it must be invalid.

The specific example was a paid garage that claimed no liability for any break-ins, any issue with the cars, etc etc. but he explained that if you are paying for a private parking, there are some expectations to the law and you cannot notice-board out of those. They are mainly a deterrent for people who are unaware of the law or these things, or made by a hapless manager.

Exactly.

In the US, there are a lot of gravel trucks that say something like

"Stay back 200 feet. Not responsible for broken windshields"

But the truth is: every vehicle on the road is responsible for not dropping stuff on the road. Especially dangerous stuff. Is it difficult in the case of gravel trucks - sure. But that doesn't matter.
