I think part of why the cameras don’t have such scrutiny is the city often has signs stating they use the cameras and will list their locations. This gives a somewhat implied consent from the driver, idk if it holds up in court but its similar to a sign at a store saying you’re on CCTV. The sign doesn’t say the CCTV could be used to track and monitor you but its implied.

The system required to make them hard wired would be immensely over complicated to allow the wheels to still turn. Where ever the wire exits would also have been additional point for leaks to occur.

However, the researchers found that these tire sensors also send a unique ID number in clear, unencrypted wireless signals, meaning that anyone nearby with a simple radio receiver can capture the signal, and recognize the same car again later

Its not quite the same ball game. Sure its not great that the government can track easily with ALPRs, but this type of tracking is available to nearly anyone and could be used for significant crimes like stalking or human trafficking. It can also be done without a sightline of the car, unlike a camera system.
