I think the main difficulty is how infrequently the devices broadcast.

You don't need to look at all tires to make a match, but the more a car has, the more likely one will be broadcasting during the window for detection.

Sort of. The problem isn’t necessarily the speed but the range. But it could be used. Bluetooth and WiFi tracking would be more likely in most real world scenarios.

Even if you can’t, if you put enough of them by stop signs and traffic lights it’s a non-issue.

Yes. I'll bet fifty of what you like there's a demo on YouTube.
