Even cheap cars now have hundreds of processors. Modules can throw errors, send the car into limp, or deactivate the vehicle entirely.
Plus, emissions.
It’s a different game now.
Don’t take my word for it. Tear into any one of the dozens of black boxes in your car and take it apart. Analyze the chips soldered on the boards. You might get lucky and find all standard chips with information available from suppliers.
Try looking at the data going across any one of the several buses transiting your vehicle. OBD is easy. The others are usually encrypted and much higher speed.
Cars are legitimately complex. Don’t just listen to the manufacturers and scoff. Look up some research into breaking the communication protocols that MB or BMW use. Compare that with GM’s newest standard. Go ahead and practice your reverse engineering skills, because these things aren’t published.
They’re made that way so you can’t repair them. They don’t need to be that complex and nothing on a car needs to be encrypted.
Sounds like the problem is lack of regulations, not people repairing their own stuff. We are letting companies create unmanageable products then blaming owners for trying to take ownership. Encryption is a solved problem, and doesn’t require a black box to be secure, in fact is more secure when it isn’t. And this isn’t the first time that Cara breaking on the road a risk. If someone put after market breaks on their car and they failed, people would die too, yet somehow we allowed that. Car manufacturers are being allowed to make anti-consumer decisions and are blaming us for them.
The problem with the black box approach is not only does it mess with right to repair, competition, and home build jobs, but even people who make cars! I’ve literally been to talks in car manufacturing events where a speaker from a large car manufacturing give talks about how hard it is making life for them. Does that car manufacturer do anything different? Nope. Whole culture is infected with “my secrets” thinking which makes everyone’s life hard. Things are at a complexity now, everything should be built to be debugged.
This thread is literally the difference between someone who knows what they talk about getting downvoted because people don’t like facts and someone who doesn’t know they talk about getting upvoted because they appeal better to emotions.
Social media has ruined us.
Yeah, Lemmy is usually pretty tech savvy, so this is kind of surprising.
It’s “some basic evidence and appeals to do some research to change your view” versus “I don’t think so and car manufacturers are just bad” with no real counter argument
