I am trying to catalog the possible sensor found on a F1 upright. Any photo of a F1 front upright with shielding and ducting removed shows a part completely covered with electronics and wiring.
My first search turned up the wheel sensor for Kistler for F1. I think I appreciate what measurements are being made, but why in the wheel vs on the hub? What would be the subtle differences that made them go to the trouble of a wheel installation?

the Kistler wheel (rim)is mainly used for tire testing and/or to measure "Grip".
(forces at the road/tire interface)
I simple terms it measures the forces between the outer rim part and the hub. Similar in principle to measure stress/strain/tension in the spokes of a wire wheel and calculate the forces on the tire in three dimensions from it.
some of the sensors you will find on an upright will/can be: wheelspeed, vertical acceleration of the upright, brake fluid pressure, brake fluid temp, brake pad wear (displacement of the pistons in the caliper), brake disk temperatur.
In some cases (during testing) distance of the upright to the ground, to determine tire deflection/squash
