As much as I tend to agree philosophically, could it not result in people making changes that endanger other road users?
Four 9/11s worth of people die every year from drunk driving. If we can't even get that under control, I don't see why being able to modify your own car is a big deal.

You can translate that to corresponding car-purchases, i.e. vote with your wallet.
Really? Which car manufacturer officially provides you a root access to your vehicle?
That, or no company wants to assume liability. In which case, go whine to your local representative. That’ll be hilarious for all involved.
> A DC power supply capable of providing 12V Hey, I just remembered my school used to have ages ago some cool power supplies (I think from Agilent?) that were very idiot proof, they had current limit with a dial that I think didn’t went over 1A or perhaps even less, and they would instantly disarm on short circuit (and indicate it with a led), and also the voltage dial I think wouldn’t go over 25V. I remember it was…
What you're describing is a lab power supply. (The "instantly disarm on short circuit" is overcurrent protection, which is a standard feature.) The name brands like Keysight or Rigol are kind of expensive, but there are a lot of no-name models on Amazon which will do the job well enough.
It's funny to hear LVDS be described as an "automotive" cable when all of my run-ins with it are for connecting laptop displays to their main-boards! (though that has a very different connector on it, and its a very general term for the signalling protocol from what I remember)
Most modern laptops no longer use LVDS for connecting the screen, but they use eDP (embedded DisplayPort). So LVDS is more likely to linger in automotive displays, while in less obsolete devices it has been replaced by either eDP or by MIPI DSI (used e.g. in smartphones).
Spoiler alert: it's still LVDS
> Unfortunately I had no other choice but to buy this entire loom for 80 USD. Fwiw, mine costs $450 from Ford. Also in the US we call this a wiring harness, with the loom being the material that goes over the wires
The car was full of issues and probably spent more time in the shop than on the road. Nissan finally had to buy it back after service techs failed to tighten the oil drain cap after an engine overhaul.
I used to work for a company that made third party scan tools. We had racks of ecus disconnected from the car with just a diagnostic connector and power. nothing got to a real car without first trying it on the rack. I remember on time we figured out a bmw (pre obdii) had the bytes offset from the standard documentation (it was a semi-standard protocol that some other cars used at the time), we went from we communica…
I spent the last week successfully reverse engineering my car / various scan tools to get the right information to diagnose a fuel pump problem (and to do so without the incredible awkwardness of many of the tools) It's pretty amazing what Claude + Ghidra + knowledgable coaching can accomplish. It was basically just setting direction, setting up an incremental workflow with the right kind of documentation, and questi…
Release it or not, but either way you’re almost certainly going to get paid back the same amount of money: $0.

Perhaps it is also about liability. Otherwise, we would have people installing OpenClaw on their Teslas.
Then why wasn't it a problem before? People have always been able to install aftermarket or possibly even hacked together physical parts. If there was liability you'd expect some sort of shield blocking access to, for example, the hydraulic system for the brakes. As it turns out though blatant irresponsibility is quite rare (depending on your definition anyway) since people have a strong self interest in not endanger…
Maybe you think daytime running lights are stupid and want to disable them for instance.

Disabling alertness sensors might worsen drunk driving actually.
From the article > Tesla offers a “Root access program” on their bug bounty program. Researchers who find at least one valid “rooting” vulnerability will receive a permanent SSH certificate for their own car, allowing them to log in as root and continue their research further. Pretty interesting. Sounds like Apple's Security Research Device Program[0], where you're loaned a rooted iPhone, but with a clear qualificati…
> Researchers who find at least one valid “rooting” vulnerability will receive a permanent SSH certificate for their own car It feels like this is something you should get by being owner of the car, and not have to do free speculative research for the manufacturer to get it.
More concretely, the expertise-required-to-access-root is in a different field to the expertise-required-to-make-wise-changes. i.e. you might know how to hack a car, but that doesn't mean you know how cars operate.
