Seatbelts and Libertarianism.

I was thinking about laws and politics recently, and I worked my mindset onto death, which then, somehow, led to motor vehicle collisions, which then led to safety devices, then to seat belts. I initially felt that seat belt laws were extremely arbitrary, but then I did much more thinking and came to a new realization. By not wearing your seat belt, you can potentially harm other people, which is ultimately much more important than your own safety. It simply isn't fair that you harmed (Or possibly even killed) another person just because you didn't have the energy to buckle up.

Example:

4 naieve teenagers in a vehicle gliding at a mere 60 miles an hour. They skip then hop a curb and tumble off the road. For a moment, consider their corpses to be glass jars. The one loose glass jar breaks the other 3 from colliding during a rolling free fall. Killing another is the ultimate violation of liberty. Libertarianism states that you have the freedom to do whatever, so long as it doesn't impede another person's freedom.

Not wearing a seat belt and killing someone else, even if you die yourself, is the ultimate breech of the Libertarian ideal. My final conclusion led me to agreeing with seat belt laws. Don't mind the huge cost that fatal car crashes cause in this case. The fact that you potentially can protect another person's life just by taking less than 4 seconds of your time to just press metal into plastic outweighs the 500 billion dollars it costs the world every year to mop up the carcasses off the asphalt roads.
