Don't worry about Tesla's being tracked. Via Bluetooth this has existed for at least 7 years [1] (was mentioned on HN as well). Tesla know (also for 7 years), Musk doesn't care 'since license plates can also be tracked'. I used it in train stations, and get hits when passing highways via train or bus. Esp. fun if you stand still due to traffic lights or traffic jam, since you can try to get a visual. The only lesson…

It’s done in Europe’s second busiest airport, Amsterdam Schiphol. I saw the advisory signs (so they can pretend that you gave informed consent by walking out of the jetbrige) up just last week. https://media.licdn.com/dms/image/v2/D4D12AQHCyctOFz_EJg/art...

> Not allowed in EU. I'm surprised, I know for a fact that some stores definitely have the ability to do that on their hardware.

Only under strict rules, i.e. anonymized one way hash not relatable to a legal person. It isn't allowed to track a person that way.

The plate is pretty trivial to fake though. For one thing you can just remove it, but it's trivial to alter with just spray paint. Or using an outdated plate, or someone else's plate, etc. it's identifying sort of how an phone number is supposed to be identifying: nominal, but not secure and trivially abused for fraud

In Europe and the US all new vehicles now have a visible ID under their front window glass, it’s called a VIN. It’s even standardized where it must be.

I wonder what the first vehicle to have the VIN under the windshield was. I believe I saw that for the first time maybe 20 years ago (USA).

The standard response to privacy concerns is usually “nothing to hide, nothing to fear.” I guess anything you send out can be used to profile you.

I was researching bluetooth low energy for a project, and discovered "Beacons": https://en.wikipedia.org/wiki/Bluetooth_Low_Energy_beacon

What's more insidious than just tracking people through the store is that the beacons can collect the bluetooth IDs of the devices they've seen and send it off to advertisers, who can use the UUID to connect a person's offline shopping with the online advertising profile they've built up for the person.

Whenever I see talk like this, I always like to post this quote that not only still rings true, but rings even louder today.

Fortunately for me, words are allowed to have more than one meaning. die /dī/ intransitive verb 2. To cease existing, especially by degrees; fade.

I explicitly said I was being annoying for no valid reason. If you want to justify something here, you should probably justify that you weren't annoying for no valid reason. Does your dictionary say that "not allowed" is specific to parents and children?
