Ford has a bunch of dipsticks working for them seeing as they took the trans dipstick out from under the hood AND this government mandated TPM tire system sucks as will when the battery's start to fail , I don't need a warning chime / light to tell me IF a tire is soft, I can tell just by the way the vehicle handles / acts and also I have a set of eyes god gave me and can tell just by looking at a tire if it is low AND then I get a gauge to confirm what my eye are telling me, hell I've been know to honk at someone around me, roll my window down and tell them THEIR tire is low, The mfg's should at the vary least offer an opt out feature on the TPM system for people who know what their doing behind the wheel knowing that their ARE also some people who are clueless with mechanical things .
