==I think the prevalent assumption on HN is that every regulation can be traced back to some accident or mistake.==
My experience on HN is quite the opposite, but that is besides the point.
==why do I have to keep those people alive with my tax payments or even be annoyed from the sight of a rail in the middle of nature.==
This is libertarian ideology in the real-world. Your argument is that your annoyance is as valuable or more valuable than someone else's potential death. In a civilized/democratic society, we have created a governmental system to make these decisions for us and to the betterment of the country at large, not just you. Stop lights are a regulation and annoyance to my car driving, if I stopped heeding them, do you think that makes society better or worse off?
==I also think that most accidents happen from overtrusting a safety gear==
Based on what? Do you have any evidence or just your personal observation/assumption?
It seems like you've lost the forest from the trees here. Specifically on safety belts, they save many more lives than they could ever cost as evidenced by empirical research:
==Seat belts dramatically reduce risk of death and serious injury. Among drivers and front-seat passengers, seat belts reduce the risk of death by 45%, and cut the risk of serious injury by 50%.==
Well, I am not a Libertarian. I am for regulation in many cases. The difference between a safety rail and traffic lights are this. When I approach an intersection then my health depends more the prudence of the car's driver also approaching the intersection and crossing my path. So putting traffic lights people at least know who can drive and who should stop. But a cliff is an obvious threat. There is nothing insidious about it. If that cliff would be close to an elementary school - then I would be for safety rails, though. Because children are not responsible and hence have to be protected from them self.
Regarding safety belts - I think you didn't get my point. I didn't say they aren't saving lives. I said that back when they didn't exist people drove more careful. With all those protection in place in cars - many people drive more reckless having those protections in mind.
But there are also other people around and animals and high wind speeds and any number of other factors that impact safety. I bet you still follow stop lights when nobody is coming the other way.
==Because children are not responsible and hence have to be protected from them self.==
This is an argument for putting rails on cliffs, as children are not barred from cliffs. Seems like you have talked yourself into a pretzel.
==I said that back when they didn't exist people drove more careful. With all those protection in place in cars - many people drive more reckless having those protections in mind. ==
I get the point, people may drive more recklessly because they feel protected by the seatbelt. I would say that all regulations are a cost-benefit equation. In the case of seatbelts, the benefit of more people living is larger than the cost of lost freedom.
