This is a really interesting article. One question answered for the author: I believe TPMS sensors have an RFID-style mode, so that handheld programmers can access them without waiting for the slow reporting period.

I have experience with how finicky these sensors can be. I installed a radar detector in my car (legal in my state, and wise considering the unusually aggressive speed enforcement that appears once every few weeks along the highway I drive). I stashed the radar detector's control box in some empty space between the glove box and an air duct. The TMPS receiver module is also located in this area and cannot receive signals while the radar detector is powered on. I assume this is broad-spectrum EMF and I need to layer the control box in aluminum foil.
