If you're going to try and track this stuff for real, keep in mind most devices like this use motion sensors to go into low-power mode when stationary and only transmit on the move.
We talking MEMS/inertia detection, vibration detection or auto-geo-fencing?

TPMS is also common and detectable.
This is tire pressure monitors for those that don't know. Didn't even cross my mind...

If low cost is the goal, consider a voltage measurement device. ICE engines have electrical systems that run ear 13V when the engine is on, and ~12.5-12.8V when the engine is off
That would require plugging into the wiring. At that point you no longer need a battery and can just use the car's power.
It'd be cheaper to buy an RTL-SDR and an LTE antenna than this tinySA. I'm not convinced that a layman would have enough practical experience with radio's to detect these signals though. The bands used for IoT aren't exclusively used for IoT either - they'll contain "normal" LTE signals too.
RTL-SDRs have a typical usable bandwidth only about 2 MHz, so that is going to rule them out of any real usable LTE related decoding and detection
You won't be doing any decoding w/ a tinySA either.

Is that accurate? The Willis proceedings were about events around 2021, so that's only 4 years at best
They introduced stuff from a really long time ago as evidince of people knowing each other or dealing with each other. Like "you were at X's house then so clearly you knew them" type thing. I don't recall exactly what the context was because the big takeaway was the retention of records.
Back in 2006 that was an eye opener for me.

Certainly an interesting thought if you have a very old diesel. I would wonder if all the metal would hamper an EMP pulse that you could safely generate at home. Diesel's going back 20+ years still have ECUs as well, not to mention the rest of the vehicle's electronics could be at risk. So it would have to be a properly old or unique vehicle.
It's an interesting idea. The "obvious" route would be to tear down the vehicle and remove all the ECUs you want to save, then administer the zap. But at that point you probably find the tracker hardware anyway, unless it's really buried in some upholstery or something.
That said, whilst it is a known threat vector, I have no data on how often its actually exploited. It might be a lot of work for nothing.

I’m not sure what point you’re really trying to make here. This is a thread about detection methods of an extremely invasive (and rare) method of stalking, which yes is a subset of a data privacy issue. The fact that data brokers can get a lot of location and other data about you is irrelevant to the discussion. > or do you believe you can hide from a stalker if everyone else under the sun knows you location. I’m not…
My point is that what they are doing is interesting and commendable but if they want to effectively help stalking victims they are barking up the wrong tree and that there are much better ways to spend time and energy to help the issue at hand.

BLE transmissions go much further last time I experimented with them [0]. However the problem of anonymity comes into play since they frequently generate new MAC addresses. [0]: https://news.ycombinator.com/item?id=38252566
