That tire pressure readout on your dashboard? It's not hard-wired. It's bluetooth. And susceptible to this type of surveillance.
Edit: Significant correction in first comment. Still spyable, but not bluetooth, says commenter.

@Osteopenia_Powers@newsie.social @jcrabapple@dmv.community TPMS isn’t actually Bluetooth, it’s an unencrypted wireless protocol on either 315 MHz or 433 MHz, depending on locale. The lack of encryption is part of the problem, as each sensor broadcasts a probably-unique identifier. Bluetooth is much more private, though still usually identifiable.
