I mean it’s magic right? It’s gotta be magic. How would they even be powered? Or connected to anything? You’re telling me they just sit inside a tire and know shit and communicate it?

I’m a used car dealer, and it’s something I often have to service on cars.

Inside the sensor you have a battery like those found in watches:

They die after a few years, and have to be replaced. This is often serviced when people buy new tires every few years.
