On: Federal judge calls Flock 'indiscriminate mass surveillance'

What do you mean direct TPMS ID? Read all 4 tires as a fingerprint? Can you do that remotely at speed?

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.

Tire kicking suddenly a sign of privacy mindedness, not rude Craigslist window shopping behavior

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.

You could just mount them to a bunch of fleet vehicles [0]. Hopefully they don't pick up any stray signals from nearby vehicles moving at low speeds (relatively) around them or have any AI, API, or Cloud integrations to combine that data with other mobile and stationary telematics.

I believe people have demonstrated this works at up to 100m with directional antennas.

Honestly, I was shocked by how many of them were successfully decided by rtl_433 running on a cheap RTL-SDR inside my house. I don’t live on a busy street. It picked mine up first but snagged a bunch more through the evening

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

The only way to fight against this dragnet is flooding these devices with fake data.

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