I think that since this is the "road cycling" sub-forum, y'all are missing the intended use case. I think the TyreWiz could make sense for CX, MTB, or gravel racing, where the surfaces can be far more variable than we usually see on the road. Especially in CX, you might want to know during test laps how the course is "acting" on that day so you can tune your tire pressure, and in XC MTB where you might want to lower pressure for certain sections and raise it for others.
