A place to discuss privacy and freedom in the digital world.

Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.

In this community everyone is welcome to post links and discuss topics related to privacy.

Many of us know how bad modern cars are for privacy. Yet many of our friends and neighbors do not realize how intrusive it really is. I linked a blog entry from Mozilla's investigation about car privacy. In that blog is a link to their make-by-make analysis. The amount of very intimate information a modern car collects is honestly appalling. It includes health data, real time mood information, weight gain or loss, and so on. And it does so even for passengers.

The web has many resources talking about this problem, but almost no resources on what to do about it. I know the simple thing is to say, "just drive an old car bro!" That's fine if you can, but not everyone can. Also it has drawbacks like more maintenance. Sometimes less safety if it's older than certain safety features. For the purpose of this thread, it is more interesting to focus on newer, surveillance enabled cars which are the majority of what people drive on the road today.

Some people have figured out how to bypass the surveillance package on some cars. One way is to uncouple the antenna it uses to phone home. Other times you can bypass the telematics module or remove a fuse that powers it. I feel like we really need a central model by model repository of information.

Past that, how do we prove it has worked, if we do it? Has anyone reading this tried to use an RF detector to see if their car is still trying to phone home, after they have bypassed telematics? What are your experiences? I want to buy one and use it to test my own car, but the info on the web seems sketch.

Depends entirely on your car make and model. On many models you can disconnect or remove the fuse for the telematics control unit (TCU) and it's as simple as that. However you won't receive any OTA updates that will likely solve problems. And if you reconnect to get them, there's no guarantee your car doesn't suddenly dump all your personal data obtained in the meantime onto company servers. Further I find it more and more likely that OEMs either already have or will add a ToS that requires you to keep all this stuff connected, and they'll argue that the data collection is part of the sale.

Slate seems to be the only brand currently that intends to deliver vehicles with zero connectivity required.

Do you mean these guys? That's the first I heard of them so thank you for that! I thought it would turn out to be a European make, but they're on my side of the pond. A zero-connectivity electric car would be the dream. I like the idea of electric cars but so far they have all been even more wrapped up in telematics than internal combustion cars.

[–] artyom@piefed.social 9 points 22 hours ago (3 children)

Yes, zero connectivity, relatively affordable, highly customizeable, and repair-friendly (for now). The only connectivity is through the phone app. Only downside is you have to buy a stupid truck. They could have made it a lot cheaper as a coupe.

[–] jmill@lemmy.zip 2 points 14 hours ago* (last edited 14 hours ago) (1 children)

I think it's a truck for regulatory reasons. Trucks get a pass on a bunch of things that can be a regulatory issue for cars, because of course they do.

They are offering kits to make it a van or SUV. Still no coupe, but better than a truck for many purposes.

Maybe if it sees market success, they'll branch out into other body styles. I want a car too, not a truck.

[–] artyom@piefed.social 5 points 22 hours ago

That would be nice. But then I'd be driving around in my stupid truck like an idiot!

[–] ColeSloth@discuss.tchncs.de -1 points 11 hours ago (1 children)

Not really true for pricing. A small truck isn't much more weight or material than a sedan.

[–] artyom@piefed.social 1 points 10 hours ago (1 children)

It's nothing to do with weight or material but aerodynamics.

[–] ColeSloth@discuss.tchncs.de 0 points 2 hours ago (1 children)

Riiiught. How is that going to make it cheaper? They can use a bit smaller of a battery to get the same range? That size difference would just be around $500.

[–] artyom@piefed.social 0 points 2 hours ago (1 children)

No, more like several thousand. In addition to charging faster.

[–] ColeSloth@discuss.tchncs.de 1 points 1 hour ago (1 children)

Lol. No it isn't. The batteries are only 53kw\h in size and they're using shitty NMC batteries instead of LFP (or other) batteries because they want the full $7,500 tax credit. $500 would more than make up for the aerodynamics. No manufacturers want to use those batteries anymore because they only last like 2\5 the charge cycles compared to LifeP04, and it get even worse compared to other batteries coming out right now. Really, putting those batteries in something with only a 150 mile range is kind of a shitty move, IMO. You'll need a new battery after 100,000 miles. Fine for a cheaper option I suppose, so long as the batteries are easy to replace and it won't cost $5,000 in labor.

[–] artyom@piefed.social 0 points 1 hour ago* (last edited 1 hour ago) (1 children)

LOL yes it is.

The batteries are only 53kw\h in size

That's the 150 mile model. No one is going to buy that. That's just the model they offer on the lowest rung of the price ladder.

because they want the full $7,500 tax credit

...there is no more tax credit.

No manufacturers want to use those batteries anymore because they only last like 2\5 the charge cycles compared to LifeP04

...WTF are you talking about? Virtually everyone is still using them for much higher energy density and power. Almost no one is using LFP.

You'll need a new battery after 100,000 miles.

Incorrect again.

You should really learn more about what you're talking about before stating it so confidently.

[–] ColeSloth@discuss.tchncs.de 1 points 7 minutes ago

LFP is only typically about 15% less energy dense than NMC. You're dead wrong about EV manufacturers moving off NMC. LFP is cheaper to make and lasts way longer. Only the US has more issue, because we've pissed off everyone else and getting lithium can be a potential supply chain issue.

The tax credit didn't get killed off until the end of 2025. Way after Amazon had already purchased the batteries from a South Korean manufacturer, that was chosen because they have a fab in the US and it was going to meet the EV full tax credit (this is well known and documented. Go see for yourself).

You also don't know that everyone will buy the bigger battery option. The range is supposed to be like an extra 100 miles, but Amazon hasn't given price differences yet. If the base model is $25k, but the extended range model is over $30k, the smaller model may very well sell good. They're just being made as city trucks. Neither battery is big enough or charges quickly enough for long road trips, so a lot of people may not care about the extra range. Depends on pricing.

The 100k battery replacement is pretty spot on. Smaller batteries means more complete charge cycles done faster. NMC noticably degrades after around 800 cycles. The batteries will start needing replaced at 10 years and 100,000 miles.

Jeff Bezos is a named investor of Slate, so i wouldn't trust it

[–] artyom@piefed.social 14 points 22 hours ago* (last edited 22 hours ago) (2 children)

Would you like to recommend another brand that has zero data connection and also isn't invested with Bezos?

[–] Manalith@midwest.social 1 points 4 hours ago* (last edited 4 hours ago)

I haven't looked into them really at all, but their phone app I would consider a data connection, also how is it updating that? Just Bluetooth? Maybe they have that info, like I said, I haven't looked into them much yet.

[–] FineCoatMummy@sh.itjust.works 5 points 22 hours ago (1 children)

And if you reconnect to get them, there’s no guarantee your car doesn’t suddenly dump all your personal data obtained in the meantime onto company servers.

It's a good point. Also I wonder if OBD-II can do that. A person could disable the port, but that may make it hard / impossible to get the vehicle serviced.

[–] artyom@piefed.social 7 points 22 hours ago

Yeah OBD is the main diagnostic port so that would certainly cause problems LOL

[–] Dequei@piefed.social 1 points 23 hours ago (1 children)

There is a private mode in my Kia Ev3, but yeah, It disables almost everything.

[–] artyom@piefed.social 11 points 23 hours ago

What are the chances that it's just lying? Or re-enables itself periodically?
