That is a fascinating idea, Richard.  All of this telemetry data happening instantaneously on a display, right before your eyes.  Somebody who figures it out is going to make a lot of money.

 Given how reliable these seem to be, even spinning around on the outside of the wheel, I wonder how long before other sensors could be added wirelessly to a vehicle?

Oil pressure and temperature? Water temperature? Transmission?

Maybe this is already being done...

    I never checked my tire press by gauge daily. And my van’s a daily driver. The tpms is my lazy way. :-)
    Seems to be pretty true , within a pound or two, of my hand gauge reading.
