Has anyone experienced a case where they needed an over-the-air safety update/recall performed, but weren't able to because they removed the cellular modem? I'd like to think failure to apply an OTA safety update would trigger a mail-out notification requesting you bring the vehicle into the dealer. But that's probably optimistic...

What type of fucking "safety" update could be performed?

If the car has a recall or safety issue with the suspension part failing prematurely, what possibly could some software nonsense do?

Difference is most of those things you mention overwrite their data in a few days or weeks. Even doorbell cameras, no one's stuff is being stored indefinitely.

How do you know? Most of these are cloud connected, how do you know they aren't storing license plate information, or face data, or audio data for extended periods of time in the cloud?

Nothing comes for free, so what's the profit angle to do this? Government is the obvious customer, but that would leave a papertrail too if such deals were worked out especially asking for perpetual storage until the heat death of the universe.

If it keeps collecting telemetry it could upload it later if it ever gets the chance. Better it isn't collected in the first place.

That also means it isn't passed to your phone via android auto / carplay. Phone GPS is much worse than car GPS for road navigation. It's basically unusable.

I've successfully used it in my 2006 Ford Fiesta for about 10 years now...

The reliability is way better than GitHub's uptime.

Better even than my car's uptime.

You must work in telco.

99.9999% or it's unusable :P

I wonder if insurance would refuse to pay out in the event of an accident due to this modification?

They would have to prove the modification caused the accident.

No they don't.

They can deny any claim for any reason, the onus gets flipped on you because if you want to fight back, you have to take a multi-billion dollar company to court .

Or by the FBI, NSA, CIA, DHS, or some other interested entity.

If a TLA is interested in you then you don't need to worry about a data log in your car.

I find comfort in thinking that, if a TLA is interested in me, they have to work a little bit harder.

Are you implying that we shouldn't be annoyed at Flock and forced GPS tracking in cars because my ignorant neighbours have a cloud connected doorbell?

Because I am instead annoyed at all three.

Not necessarily my neighbours, but the companies selling this spyware.

It does produce a local Wi-Fi network but there's no evidence that it supports internet communication. That would be considered a hotspot, which not all carriers even support.

I've never understood how this can be limited in practice: surely as far as the carrier is concerned, all traffic from the mobile device is the same (unless there are identifiers on the traffic coming from hotspotted devices via the mobile device). Here in Australia we've never had any form of hotspot detection/segmentation - if you have a data plan, all data features work (across all carriers). I do recall lots of o…

I believe there’s some stuff like that for commercial things. One project I worked on used an ‘IoT portal’ for cloud based telemetry (at the customer’s request) and we had to get a special SIM card for it (although I don’t know if this is still needed.)

Your phone voluntarily tags the hotspot data with specific TTL values which carriers use to segment the data. Not all carriers work the same though.

> voluntarily tags

Aah, you mean ‘snitches’. :P

They are probably confusing google auto with bluetooth.

On Android there is an option called "Bluetooth tethering - Share phone's internet connection via Bluetooth" . If it is On and you are connected to the car's bluetooth it will have internet access via your phone.

That's Bluetooth PAN. I would be very surprised that a car will implement this profile.

Your phone voluntarily tags the hotspot data with specific TTL values which carriers use to segment the data. Not all carriers work the same though.

Specifically it decrements the TTL of routed packets, so hotspot traffic will tend to have a TTL of 63 instead of 64. You could theoretically disable this at the risk of creating infinite routing loops, although android probably makes it inaccessible if the kernel has a setting for it at all, so you might have to rewrite packets in user space.
