And yet people can feel the difference between a worn tire and a new tire. Accelerometers and the torque feedback on the motor drives (both of which are already widespread in cars out of necessity for other equipment) can feel when the tires are on the edge of losing traction.
One of the changes in automation over the last decade or two is a move away from having many specific 'sensor for monitoring X', towards interpreting a smaller number of better sensors in novel ways to provide the same data.
I've been in the industry for 15 years and i've never heard of anyone that can feel if their tire are worn or not, most can tell the difference between a worn and new right after they changed(mostly psychological, as they asked it to be change and know it's new), but never feel it in their daily commute. They will only know when they check. Same as machine, if the change is gradual and slowly over a long period of time, they will only interpret that as something normal and calibrate it accordingly. It's the same reason your car won't bitch about throttle body service because the parameter is "off", or bitch about alignment because your steering is slight off center, because they deem it as "normal" and calibrate as such. They only throw up signal if the change is sudden.
Secondly, said tech already been used as a way to tell you about tyre, yet more car use tps anyway, because it's more precise and accurate.
Thirdly, people already and should rotate their tire regularly, at that time you should know how much thread the tire still have left, having an extra and unreliable "warning" would totally piss people off.
It's a feature that doesn't benefits from redundancy.
Yeah, I'm always a little skeptical about the 'feel it' claims. But computers don't have to adapt to progressive wear; I'm sure you could configure the ABS/traction control to indicate that in dry conditions consistently slipping below say 0.3g (number pulled out of ass) of applied traction implies an excessively worn tire.
Once you get below a certain level of performance, all the braking/steering assumptions involved in self driving start breaking down too.
