So the issue isn't that you're speeding, the Police stops you and writes a $50 ticket. You voluntarily speed and voluntarily stop for the fine because you voluntarily try to avoid a bigger punishment under that system. The problem is that you're speeding, the Police stops you, overreact, pretend they saw something dangerous (smelled marijuana, something looked like a gun, you were acting suspiciously, had the wrong skin complexion, etc.), you get pulled out, roughed up, hurt, or killed.
