They don’t want people modifying ADAS systems mostly, and the main requirement is SecOC, which is cryptographic authentication but the message is still plaintext. Basically they don’t want third party modifications able to randomly send the “steer left” message to the steering rack, for example.
So much this. We had a rental BYD in Greece this summer, and while it was actually great car in general the mandated “assistance” was awful.
It constantly got the speed limits wrong, constantly tried to tug me out of the correct lane, and was generally awful. It could be disabled but was re-enabled on each restart of the ignition because it’s mandated by EU regulation.
I appreciate a Greek island perimeter road may be a worst case scenario, but it did the same with roadworks on the freeway and many other situations.
Actively dangerous in my experience…
“Lane keep” yanks the wheel dangerously because it incorrectly detects the lane, or because you don’t indicate to pass a pothole on an empty road (which itself would be confusing to other road users)
Forward collision warning has misfired on 2 occasions on me in the last 3 years
The main issue is that so many cars have broken “auto dipping” headlights which don’t dip, or matrix headlights which don’t pick out other cars.
This automation shit should stop, but it won’t.
parking beepers are reasonable, they simply come on occasionally and don’t actually interfere when they go wrong. The rest of it just makes things far worse at scale.

My Lexus is afraid of a bush behind my garage in the alley. It's on a neighbors property and not really overgrown, but my car refuses to get within about 5 ft of it. Makes backing out a nightmare. I haven't figured out a way to disable it, and have considered just selling this 2025 NX.
Yes, and to do that, CAN must be encrypted. The idea isn't just to secure it from hackers. The idea is to secure it from owners.
I integrated SecOC on some ECU's at work. I hate myself for it. I frigging hate what they're doing with this. I think it's going to make cars less repairable, less modifiable. It's a horrible horrible stupid initiative in the name of "cybersecurity".
I understand notionally where they were going, but it all sort of went off the deep end somewhere along the line. A concern that someone buying some "mileage blocker" or whatever other shady device off of AliExpress might be vulnerable to the device steering their car into a wall is actually quite a valid one, but of course the solution is some overcomplicated AUTOSAR nightmare that doesn't solve for key provisioning in a way to make modules replaceable.
I have less trust in their good intentions. I think OEM's want to lock down their platforms in order to squeeze extra revenue streams. And I tend to be quite charitable with my interpretations.
As an aside, I checked out your GitHub. Cool projects, the vag flashing tool looks super useful, might actually give it a spin in sive development projects.
The ADAS systems mandated in Europe are insanely intrusive. I had a few rental cars in Europe this summer and wanted to send them off a cliff. (and I'm not an auto tech luddite, I've had modern cars in the US with autopilot type systems, lane keep, blind spot warning, rear traffic assist radar, forward collision warning, etc. IMO rear traffic assist/FCW/AEB tend to work really well, autopilot pretty well, and lane keep and blind spot silly gimmicks at best).
Bring on the full self-driving cars, or let me drive my own car. This human-in-the-loop middle state is maddening. We're either supervising our "self-driving, but not really" cars, where the car does all of the work but we still have to be 100% aware and ready to "take over" the instant anything gets hard (which we know from studies is something humans are TERRIBLE at)... Or, we're actively _driving_ the car, but you're not really. The steering feel is going in and out as the car subtly corrects for you, so you can't trust your own human senses. Typically 40% brake pedal pressure gets you 40% brake pressure, unless you lift off the throttle and hop to the brakes quickly, in which case it decides when you apply 40% pedal pressure you actually want 80% brake pressure. Again, you can't trust your human senses. The same input gets different outputs depending on the foggy decisions of some computer. Add to that the beeping and ping-ponging and flashing lights in the cluster.
It's like clippy all over again. They've decided that, if one warning is good and helpful, constant alerts are MORE good and MORE helpful. Not a thought has been given to alert fatigue or the consequences of this mixed human-in-the-loop mode.
