Geography might also be a decision factor here as well. Given that you're in Austin, TX....you might not necessarily need this. If you were further north where massive potholes are an annual road hazard and sometimes unavoidable, you might be more inclined to consider this. Not saying that TX doesn't have potholes, but they don't seem to pop up as quickly and ominously in snow-bound areas.
