“Tire pressure monitor system dashboard icon is ridiculously non-intuitive. Both my wife and daughter have been baffled by it because the icon DOES NOT LOOK LIKE A TIRE! Neither are stupid, one is a college grad and the other is a junior at ASU. The icon is a cross-section of a tire, and none of them know what a tire cross-section looks like. Because of this, they have driven on dangerously under inflated tires without knowing it. Fix the icon SO IT LOOKS LIKE A TIRE! Thank you.”
