There’s always gonna be these people knowingly breaking the law if they can easily afford the fines. Do you think she would keep driving without her seat belt and smoking wherever she pleases if she was fined say 10% of her yearly income every time she was caught?

Or you know they could stop breaking the rules the rest of us have to follow.
