Sacrificial anodes are as good as tea leaves in a car. In a previous post I put in a link that explains. In a nutshell, it works for marine and under ground pipe applications because the water and soil will pass current and complete the circuit. There's nothing but air around a car, so nothing to complete a circuit. To top that off, rubber tires are an excellent insulator! Notice that you haven't seen an electronic rust inhibitor for cars offered lately? Apparently there is a law against it (federal) because they physically can't work!!
