TPMS Upgrade and auto-fill

If Ford does not implement a system to automatically maintain tire pressure in each tire, then PLEASE implement this: in today's USA Today 5/26/12, the review of the 2013 Nissan Altima, the paragraph starts "Thoughtfulness is infused." When you start putting air into a tire, the flashers come on to show the tire is being filled with air. The horn chirps when the tire is full.
