An under-inflated tire will fail prematurely, will increase the likelihood of the driver loosing control and will decrease fuel mileage. An under-inflated tire will have higher side wall and edge temperatures. The nascar boys run a inferred temp gauge across every tire they pull off. They know that if they can get consistent temps all the way across the tread, the overall temperature will be lower, the tire will last longer, the corner speeds will be higher and the car will spend less time in the wall.
I too, hate the fact that politicians think they know how to build cars better than Detroit.
Since around 1970 they have never failed to help Detroit raise the price of new cars, whenever the opportunity presented itself.
I'm afraid I have to go with this one. The technology has been around and used on GM cars for 20 years that I know of. A simple low pressure warning light as opposed to a continuous digital reading would be very inexpensive and could be easily retrofitted if a person chose.
