Summary Privacy & Surveillance Champions
Can't Hide Your Stride is an empirical research study demonstrating privacy and surveillance vulnerabilities in unencrypted automotive TPMS transmissions. The paper champions human rights protections—especially privacy (Article 12) and freedom of movement (Article 13)—by exposing how static, unencrypted identifiers enable systematic vehicle tracking at minimal cost ($100/receiver) and explicitly advocates for policymakers and manufacturers to implement privacy-preserving designs. Published in an open institutional repository, the work embodies freedom of expression (Article 19) and supports remedy through policy reform (Article 8).
I have an RTL SDR setup in a retail business receiving temperatures from sensors around the property. Besides the neighbors' weather stations I see a lot of TPMS coming, presumably, from the parking lot. I see the same cars regularly. I could definitely correlate them with the POS terminals and identify individual customers.
I built a demo of this back when I worked at Qualcomm in Seattle; match this with WiFi beacons and you can trace a person fairly well. It's been over a decade, but at the time both iOS and Android would send pings fairly frequently to all known WiFi networks looking to see if they should switch to a faster one. With your device ID, list of SSIDs you know, and your TPMS data, a person can learn a lot about you.
Like, where do you work? Where do you stay (Hotel SSIDs)? Who are your friends (other people's home SSIDs)?
Thought this was going to be about reading the road like the groove on a record player. Apparently it is about cleartext radio signals and vehicle-specific identifiers.
Most places where this would be legal there are probably much more effective ways to do it at the POS, even non-biometrically. Although yes you might consider usng TPMS as part of an ensemble.
And this is what I exhaustively tell people who insist that [tech company] is listening. My reply boils down to, "Why would they need to when you already send them everything in writing?"

FW Ratio: 50%
Observable Facts
Abstract calls for systemic change to 'design a more secure and privacy-preserving TPMS' as policy imperative.
Inferences
Advocacy for policy change frames rights-respecting social order as necessary response to surveillance threats.
Surveillance threatens dignity through loss of autonomy over personal information. Paper implicitly defends dignity as foundational by exposing violations.
FW Ratio: 50%
Observable Facts
The paper infers 'potentially sensitive information such as the presence, type, weight, or driving pattern of the driver' from passive transmissions, demonstrating surveillance of personal autonomy.
Inferences
Exposure of driving-pattern inference frames surveillance as threat to personal dignity and autonomy.
