I saw this article earlier:
Tesla ‘going bankrupt’ is endpoint of protests, says local organizer
In the spirit of right to repair, self-hosting, giving a second life to old devices, and limiting data collection by car companies:
- What are some considerations?
- Are there any projects worth keeping an eye on?
An example that came to mind was Valetudo, which is a cloud replacement for vacuum robots enabling local-only operation. Some robot vacuums are easy to install this on, and others require more invasive modifications.
What I’ve found so far:
Something else that people don’t think about besides the backend server is the connectivity. A lot of these cars use LTE with eSIMs that can’t be replaced, and getting an internet package for it will be next to impossible since Tesla gets them at bulk rates. Once upon a time cars did allow “bring your own SIM cards” but not anymore. Also as cars get older the cell networks get shut down. Some companies did offer upgrades but that was few and far between. Most just said “sorry, you’re SOL”.
So even if you could hack your car, your car won’t have any way of talking to a custom endpoint.
And this is another reason why putting internet on cars is a bad idea
I mean, what’s the alternative? It’s not like it has to have internet. Anything internet connected is mainly quality of life:
- Traffic
- Remote (app) features
- Music
Except maybe Teslas, damned if I know what they do. But they’re nice to have things that generally require realtime updates but the car functions just fine as a car without it.
The right to repair. It’s going to require the ability to make changes to the software on the vehicle. At a minimum the ability to replace the public encryption keys used to communicate with the servers. The bootloader and software is probably locked behind signing keys; so you need to be able to disable or add your own keys. I doubt anyone has access to the full protocols used to communicate with the servers. So, the full technical standard need to be released (which is never going to happen) or reversed engineered through unencrypted traffic analysis and reverse engineering the software.
A good right to repair law could require some of that be releasable while the company is still active or all if the company goes belly up. IIRC there was a smaller EV company that went bankrupt and there was a concern that once the servers were shutdown the vehicles would be bricked. Not sure what happened in the end. In any case, cars as IOT is the stupidest idea ever created.
This is the answer. Though there’s a really small chance someone reverse engineers the whole thing, but I ain’t doin it.
Assuming that Tesla goes bankrupt, actually shuts down forever, and shuts its servers down…
At a minimum someone would have to find out where the software sends and receives data from. Then you’d have to reverse engineer the software to control the vehicles.
Then you’d have to reprogram the software to send to your C&C server. I don’t think it would really take all that much to host that… it’s getting there that’s difficult.
Yeah it’d be a LOT of constant wireshark and reverse engineering to figure out every API it calls. Then probably something in the middle to sit on the host, need to figure out https certs since you’d be spoofing the host, and of course making sure you get the responses absolutely correct.
Not impossible, but it’s not trivial anymore either.
You’d likely need all kinds of cryptographic keys to get anywhere with that. Tesla is unlikely to ever publish those, even if they go bankrupt.
On the upside: if you mod your car to get around all that, you’ll probably be able to emulate old consoles on it and play pokemon games while driving.
…But will it run DOOM?
If I had a Tesla and someone smart enough to hack into I wouldn’t doubt I could probably figure out how they build their dashboards and reverse engineer them, they’re most likely browser based or qt or something like it. It’d be too costly to do it in anything else and Id bet many spacex dashes are the same tech. But I ain’t rich enough to get one of those things so someone else has to. There’s only so many ways to draw pixels on a screen in the name of profit
They are browser based, their whole UI and much of the in car backend is a JavaScript.
JavaScript
Ah, they’re that kind of evil.
First, second and third most important point is : Tesla needs to allow the connection to an alternative server.
The fourth should be access to the api and data that are exchanged.
You shouldn’t mess with the FW of your own car even for some innocent feature like this one, you don’t know/understand the interactions that may happen between different Sw components and the hw layer, you can not provide a similar of level of testing, including some worst case scenarios, that can make your car unsafe during some problems or unforeseen conditions. And perhaps also, the car could loose its license for driving…
If tesla allows that, then we can start speaking about it. But last time I check on that was not possible
That mentality is how we got here in the first place. A person should have a right to understand and repair/modify everything happening in devices they own. Because they don’t, we get stuck in the shitty situation where Elon Musk can unlock any Tesla he pleases and I can’t refuse to send my data to him. Or any other car manufacturer. Or tractor manufacturer. Or IoT manufacturer.
Mixed feelings on this. Yeah, you buy it you should own it. But if your ability to fuck with a two-ton rolling death machine puts my ass at risk, we’ve got a fucking problem.
I have some bad news for you - any random idiot with a driver’s license and a two-ton death machine already puts your ass at risk, all the time. We call it “traffic” because we’ve just gotten used to it
I’m talking ‘I disabled the awareness requirement of autopilot’ or ‘I fucked with the object detection and here goes my beta test yolo’ or ‘I added a button to disable all the lights so I can covertly street race’ or…
And? People can already do this with most cars.
There’s a difference between ‘physical work required’ and ‘plug in this dongle and run the exe’ though
Nothing has stopped people with ice vehicles.
If you bought a live service car you’re probably shit out of luck
It’s not.
You’re better off building an open source car. Teslas aren’t complicated
