People ask me why I don't wear a seatbelt
Why don't you want to wear a seatbelt?
I think it's an injustice.
You can think what you want, but it's still illegal not to wear a seatbelt.  You are breaking the law, endangering your life, and risking a fine by trying to be the big guy.
I'm not trying to be a big guy, but avoiding the rules makes me smart.
Avoiding safety rules doesn't make you smart. It's really unsafe and there's no use in being smart if you end up dead in an accident because you didn't wear your seatbelt.
