  • I don’t remember all of the details, but I thought it was essentially the water’s surface tension that foots the energy bill when climbing a paper towel or a capillary in a tree.

    The surface of fluids like water are unhappy. Molecules on the surface would much rather be deep in the fluid because on the surface they have “dangling” Van der Waals & polar bonds to one side. You can calculate the potential energy of the surface due to all of those dangling weak bonds, & that’s the energy that is used to climb a capillary (the energy isn’t free).

    I could be misremembering though, I admit. School was many years ago…

    Depending on the car you might be able to physically disable telemetry. Here are some thoughts/ideas I’ve been collecting:

    • Hit “SOS” button and opt-out of all services through customer service. This of course requires trusting the company to actually do it.
      • It’s possible that the info could be stored locally and then uploaded when it gets serviced though
    • Remove the fuse to the modem/data communication module (DCM)
    • Disconnect wiring to the LTE antennas
    • A number of people have mentioned that they can get the dealer to disconnect the telemetry as a precondition to buying. For instance, here.
    • Jump the data communication module (DCM) cable with a ~$70 dongle to bypass just the telematics components
    • Disconnect the DCM cable, which will likely gimp the infotainment if not other systems, or remove the entire DCM unit
