I haven't seen it mentioned, but as a Tesla owner one concern I had was that if I sold my car Tesla might not get around to wiping the information it had on me. Worse there were stories of people selling cars where the new owner was given CC numbers and more of the old owner. Nice coincidence with the article is I had a 2017 Volt. Great car, hated OnStar. First just trying to make them go away is nearly impossible an…

I've bought my last two vehicles used-- a 350z and g37 coupe. The 350z came with the previous owner's Home and Work addresses programmed into the GPS.

The g37 came with five different phones paired to it, and it had downloaded the contact info of all of those phones, as per the relevant Bluetooth standard.

Also, I found a registration card belonging to someone from Cupertino behind the glove box while servicing the air filter.

I guess my point is, this stuff happens even with old, dumb cars (the 350z).

I'm a londoner and we have here a system of public transport which is controlled by cards ('oyster' cards, RFID credit card sized things - https://en.wikipedia.org/wiki/Oyster_card ). Not exactly to address your point but they're a good way of tracking individuals so I always try to pay anonymously (cash) and never register it. I should probably buy a new one every few months but usually forget. FYI anyway. Privacy a…

They can recognize your face as you tap at the turnstile. Maybe they don’t do it now, but if they currently don’t they will in the name of anti-terrorism.

Remember, pedophiles get the train too.

Won't you think of the children?

It collects 25gb of information an hour and beams it back to the car marker. So a bit more that just your location.

This is seriously scary, how easy it is to make disinformation. The article never mentions beaming all this data to the car maker. In which world could you believe that GM could make enough from the data to pay to transfer that much data? The fact is, they simply don't know what the data GM receive is, they only mentions what the computer store (and what it could potentially store). This is the world we live in, an a…

> The article never mentions beaming all this data to the car maker

you are correct, we do not know how much of the data is beamed back

> The fact is, they simply don't know what the data GM receive is

We know they send things like "braking and turning styles" which they will helpfully send to your insurance company if you want :)

> In which world could you believe that GM could make enough from the data to pay to transfer that much data?

The one we live in. You don't pay developers to log, transmit, and store data for funsies.

If there were really 25GB of data going back to GM, I can't imagine what their wireless contract costs are like.

not all data needs to flow back and compression still exists

Sure, but data that doesn't flow back isn't much use to anyone, nor much of a danger to the consumer, and no amount of compression is going to make 25GB of raw data per hour per car for 100M cars anything other than very, very expensive. They probably send very little data.
