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 to be learned here is that it allowed one to learn in 2019 Musk is overrated. But you can also learn that lesson from the book The PayPal Wars which predates this by 15 years.

> I believe shopping malls often use such signals (wifi, bluetooth) to track what your travel pattern through the mall is. They know what section of the store you spend most of your time in and what storefronts you stall at.

Not allowed in EU.

> Not allowed

This phrasing needs to die.

Not allowed is something your parents imposed on you when you were a child.

You’re not allowed to have an ice cream, or you’re not allowed to hang out with that boy.

Laws don’t not allow anything, they only sometimes impose penalties if you’re caught breaking them.

If we're being annoying about language for no valid reason, I would say that a "phrasing" cannot "die", because a "phrasing" is not a living creature.

> Laws don’t not allow anything, they only sometimes impose penalties if you’re caught breaking them.

How does it work with your parents? Do they cast a spell that prevents you from hanging out with that boy? Nobody was "allowed" to smoke, and yet...

I consider businesses who do this to track customers naughty, and I find their behaviour childish (scriptkiddie level). Therefore, 'not allowed' is exactly the phrasing I like to use in this context, and readers are expected to understand this refers to legal status.

You should also consider not everyone on HN is a native speaker, and consider to focus on the content of posts instead of minor tangents.

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.

I'm surprised, I know for a fact that some stores definitely have the ability to do that on their hardware.

Utrecht Central Station does this, there are stickers at the entrance notifying the ‘public’ of this. Or its just a sticker;p

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.
