Description: 3 panel comic of someone interacting with a cop during traffic stop
Conversation: Cop says "Do you know why I stopped you?" Driver responds "Because you're a class traitor?" Cop is too stunned to speak.
Because the speed limit was set arbitrarily low. It should be set by data, or even preferably be dynamic. If the speed limit is there to keep people safe (that's supposed to be the reason, though it's often to raise money through tickets), then it should not be set by arbitrary guesses. It's not the fault of drivers. It's the fault of law makers.
