Jokes on them, those tire pressure sensors are the first thing I don't replace. I just visually check my tires and put a pressure gauge on them if they look suspect.

Your car has a series of numbers and letters on the back of it that are unique to the vehicle, and can be used to track you as well. There are even automated cameras that can do this.
Tracking a vehicle is easy, and always has been.
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.
License Plates, Vin Numbers clearly available on the dash, Tire Sensors, Bluetooth MAC, WIFI MAC, Cellular IDs for most even if you don't pay for the service.
It's an interesting thing to point out, but we're mostly driving around with much higher power sensors than the pressure sensors.
Not to mention the cell phone most of us carry.
Dude, my car has GPS and a 4G internet connection as well as my android phone and my work required iPhone ... In a world like this, Tyre sensors are probably not required to track me.
GPS in itself does not do anything, as it does not send, only receive. but even for mobile data, on your phone you have the choice to turn on airplane mode to disable communications. on your car, there's nothing like it.
also, arguably iphones are more private than any internet connected car.
It also had a numberplate, I assume?
The point on this is the cars are broadcasting the numbers. Imagine your license plate including a loud speaker that shouted it's number while the car was running. Tracking via plate requires line of sight. Tracking it in an automated way requires a good high speed camera, text analysis computer vision to log the vehicles, and storage for all of the images. In contrast, this signal is a repeating unencrypted broadcast. I could build a Raspberry Nano device that I can sit next to an intersection and capture the numbers of every vehicle that drives by. It is also just presumably storing the number and time, so years of tracking data could be managed with a gig or two of storage.
This is absolutely a threat, and I am surprised it is not actively exploited by companies like Walmart to track every vehicle which drives by their stores and enters their parking lots. Hell, Amazon has enough vehicles out driving around that they could pretty effectively generate profiles for every vehicle in a town just by equipping their trucks with scanners and compiling the data into a behavior analysis system. Every car which drives past is read and stored. It is truly worrying.
On the other hand, my 21 year old vehicle has none of it, and my GrapheneOS phone isn't tracking me either. We didn't all just give up like you did.
I spoke with my landlord about removing power to the home security cameras, because they were Ring. He obliged my request, but I later discovered that he (in private) regards my preference as that of a rebellious teenager in need of a cause. I had to let that sink in… I’m a rebel without a cause because I don’t sip from the same koolaid as he does. Wow.
Does your GrapheneOS phone have a SIM? Because if not, the cell towers are collecting and storing your location.

Oh wow, even more reasons to hold onto my old but not enshITtified baby!
Flock in a few months: “introducing a license plate reader that doesn’t need to see the license plate. The magnet leaf you got on Amazon to get through red light cameras won’t be enough to fool our dystopian surveillance system anymore”
Flock right now advertises that they can track vehicles by bumper stickers and cosmetic damage.
They discovered a thing that everyone's known forever. Here's Bruce Schneier in 2008

Yep. I remember watching a documentary on how to disappear. Car tires and windshields were both covered, because they can contain traceable technology.
Windshields!? That's a new one
I think it had something to do with the embedded antennas, but I could be mistaken.
Your license plate can also be used to track you
You are correct, the only thing worth mentioning is when the laws were created/written it did not account for someone creating a database that is easily searchable/queried to infer all these extra habits of people.
Its one thing visually seeing someone over and over walk or drive by your house while you sit on your porch. It's another thing to now know where they came from and where they went if you were able to sit on every porch at the same time in a town or city.
This is why police tails need to be granted by a judge, but a interconnected network of cameras at the moment does not recieve the same scrutiny.
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.
Because each sensor broadcasts a fixed unique ID, the same car can be recognized repeatedly without reading a license plate. This makes TPMS-based tracking cheaper, harder to detect, and more difficult to avoid than camera-based surveillance, and therefore a stronger privacy threat.
This seems like a real stretch.
Cameras and automated license plate recognition are absurdly cheap at this point. And cameras have much greater range and reliability than whatever wireless signal interception this is, which the researchers have said is effective up to 50 meters.
Meanwhile, from the office where I sit (which happens to be more than 50 meters above street level), I can see a highway and read the license plates of all the cars maybe 100-300m away. Plug in a cheap phone as a simple webcam and I can probably log all the license plates that drive by, maybe even correlate that to makes and models of vehicles for redundancy.
And who's going to detect that I've got a cell phone camera pointed out of my office window, or that I'm running that type of image recognition on the phone?

TIL that these sensors transmitted via a wireless signal rather than being hardwired. I've never heard of them needing to be replaced due to dead batteries.
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.
TPMS batteries last a long time because they are transponders, they use very little energy, but they eventually die.
The batteries last about 10 years.
