"We" is society. We have legislatures that pass laws. If you don't like it, there's a ballot box at which you can show your displeasure.
So why do people get pulled over and cited for not wearing a seatbelt?
In a vacuum, I would oppose mandatory seat belt laws. However, as I've expressed on this forum many times, in the society in which we live, non-seat belt users pass the cost of their failure to wear seat belts onto the general public. When a person is severely injured by his failure to wear a seat belt, the public is forced to bear a portion of that cost in things like response by police, fire, and ambulance, hospital stays, increased insurance premiums, etc. If society is going to have a policy that requires me to subsidize part of the cost of not wearing a seat belt, then the only fair trade is that we have laws requiring their use. To be clear, this is not my ideal; I would much prefer a system in which society did not subsidize the behavior of non-seat belt users, and then I'd be perfectly comfortable with allowing people to wear or not wear seat belts as they choose. But life isn't that way.
Which is your MADD chapter?
I don't have anything to do with MADD, and, frankly, I really don't care for it as an organization. All the same, though, I really don't have any particular desire to die at the hands of a drunk driver. Do you?
Our society is being misled into tyranny by false statistics wielded by career bureaucrats with an agenda who are never weeded out by elected representatives.

This is a problem associated with socialism, not a problem associated with liberty.
