But then how would you alert people that their wiper blades are wearing down, and automatically ship them new ones?

Well, obviously, your car can count cycles on the electromotor moving the wipers. Then you apply statistical wear and tear, maybe even geofenced, and your car orders new wipers. Same with tires. Simple as pie ;)

BTW, I would have zero interest in that feature.

I think the most important part would be preventing any third party wipers from effectively wiping by disabling them!
