How difficult would it be to have the TPMS give a quantitative measurement of tire pressure? With the current system, it's difficult to tell from the alert whether it's just a low pressure situation or an actual flat. It's not that big of a deal normally, but when you're driving on an icy, windy road with wife, kid, and newborn, the TPMS alert is not only perplexing but stressful. As with the rear view camera, the TPMS goes into the half-assed department of not going all the way. Grrr.
