I learned a long time ago some folks are just set in their ways and no matter how you explain the benifits of some devise, they will come up with a way to say it isn't needed. Those of us that see how something "could" keep us safer, might jump at the chance to purchase said item. I know from first hand experiance that tire pressure monitor systems can and do help in many situations, and I am a beliver in owning a system. As I always say, you get to spend, or not spend your money anyway you want. The original poster has seen the reason so many of us have decided to buy what makes us feel safer.
