flag TPMS in cars emits unencrypted signals, letting strangers track vehicles without consent, raising major privacy concerns.

flag Researchers have found that tire pressure monitoring systems (TPMS) in modern vehicles emit unencrypted radio signals with unique IDs, allowing anyone with a $100 receiver to track cars without consent. flag Over ten weeks, they collected over 6 million signals from 20,000 vehicles, accurately monitoring movements and routines from over 50 meters away, even through walls. flag Since TPMS was designed for safety—not security—current regulations don’t address these privacy risks, leaving drivers vulnerable to tracking by hackers, criminals, or manufacturers. flag Experts urge automakers and policymakers to strengthen security standards for vehicle sensor systems.
