We have plenty of speed trap towns like that around here. They want lower property taxes, so they augment their income using bullshit fines they give to out of towners. I’m sure they’re shittier to poor people and people of color like all cops are, but really they want someone who will pay the fine and lives far enough that they won’t go to court.
It is just one of several reasons traffic fines should go to the state or federal government.
