Today I learned that nearly every modern car has four tire pressure sensors that broadcast a unique ID in clear text, so a basic Raspberry Pi scanner can track when your car is nearby.

:) Remind me to stick with increasingly vintage vehicles.
It's all vanished up its own arse.
I'd rather pay a restorer than a manufacturer these days. :)
@MattMoose @mikesax I would buy from a used dealership that clipped all the rfid tags and other (eg cell) antennae.
Or better, if you wanted to get into the auto industry, disrupt all the things by selling modular cars certified maintainable by …
Waitaminute 🤔 now that I think of it, @iFixit, you want to get into the auto industry? Make me an electric car plz?
Set the bar for fewest microchips.
@mikesax surely this is not news, though? Did people not know this?
@mikesax not all cars use 433 MHz sensors. Our Volkswagen uses the wheel speed sensors to calculate minute speed differences. But is on all the time :)
I uses rtl_433 to capture temperature sensor data at home. My home assistant got flooded with new sensors, thousands of them, because it wasn't possible to filter stuff before they were discovered by home assistant as new sensors. All of these were tire pressure sensors of cars driving by.
@mikesax wow. On one hand, I get why they'd need unique IDs and I could see it being unencrypted just for cost.
But up to 50 meters away? That's just absurd to me.
Holy shit, I knew this felt familiar.
The #VW ID.4 does not have TPMS sensors. It calculates tire pressure by measuring tire rotation. It is connected to the cellular data network independent of your phone.
@Stinson_108 @reijomancer That's... Even worse.
