A lot of these features seem to assume that you're driving on a multi-lane motorway with well-marked lanes. I'm constantly being nudged by my ID.3 one way or another on rural roads. You can turn it off, but it turns itself back on the next time you unlock the car.

Maybe that's part of why VW had to fire 100k employees? They've been lately doing a subpar job designing cars.

I think it’s a legal requirement, because it’s the same for Tesla.

The speeding chime is legally required to be reset to on after every trip. But I find the speed signs are very rarely missed (model 3 highland), also its a single press on the main screen to disable. My warnings are +99% genuine cases where i need to slow down and I bet that’s true for +99% of people who have these system.

That's strange. I was reading through this thread nodding my head like "Ha, my Tesla doesn't have these annoyances!" until I saw your comment.

I'm guessing though that you're in the EU (I'm in the US where it is almost considered criminal to go speed limit on the highway)

Re:Every new car sold in the European Union must include a d... by johanvts on Wednesday July 08, 2026 @05:07AM (#48829479)
Yes, in the EU. On the plus side speed limits generally are higher than in the US.

Lots of bad road design in the US, where the speed the road is designed for and the speed limit assigned have almost nothing to do with each other.
Re:Every new car sold in the European Union must include a d... by abustamam on Wednesday July 08, 2026 @01:08PM (#48834464)
Agreed. I live in a relatively new suburb of my city (built in 2022) and it was built past what would have been called "the boonies" a decade ago.

The way to get to the city proper goes through country roads that probably used to only get a few dozen vehicles per hour, now having to handle massive traffic due to the new developments in this area (they're still building!)

They're working on reworking the roads but the speed limits are nonsensical because of this history.

Re:Every new car sold in the European Union must include a d... by jk3000 on Wednesday July 08, 2026 @03:19AM (#48828653)
Correct. I have reasonable insight into that particular world. Most none-sense is regulatory. There is less room for variation than one would assume too. Ironically, this is, in no small amount, reason for issues in competitiveness: ain't no cheap car with all these additional assistants. Especially for low-margin models it is devastating.

In older VW Polos (at least) it was easy to disable that feature with two clicks on a physical button located on the steering wheel. Not so on the ID.3, and other newer Volkswagens, unfortunately.
Re:Every new car sold in the European Union must include a d... by petre on Wednesday July 08, 2026 @02:05AM (#48828134)
One can still make a good design within the legal requirement. It doesn't say how many dB the beeper has to have or adjust the level of assistance. Maybe pressure from Chinese manufacturers will force them to get their stuff together, cut back on the user hostile design.
Re:Every new car sold in the European Union must include a d... by dzhiurgis on Wednesday July 08, 2026 @01:56AM (#48828066)
At least with Tesla you have massive ecosystem of third party add-ons, including defeat devices.

I do wish it was even quieter tho. It's kinda of a shame you got a quiet EV but then add annoying bingbongs.

Re:Every new car sold in the European Union must include a d... by Cthulhu_ on Wednesday July 08, 2026 @04:12AM (#48829054)
That may be one reason, the other being they lost the Chinese market almost overnight a few years ago.
Re:Every new car sold in the European Union must include a d... by sehansen on Wednesday July 08, 2026 @07:51AM (#48830715)
No they didn't. They had a hiccup in 2020 when the transition to electric cars really started accelerating but after they got their own electric cars into mass production they've reclaimed the top spot at 13.9% of the Chinese market. That's just ahead of Geely at 13.8%, Toyota at 7.8% and BYD at 7.1%.

It was hard to find reputable numbers for all of Q1, so my source is only for january and february: https://www.reuters.com/business/autos-transportation/volksw...

Annoying for sure but on VWs you should be able to add lane assist and speed limit assist as shortcuts on the screen and click on them to turn them off. Again, annoying but I would like drivers that have been caught speeding to have them turned on permanently as punishment for X months.
Re:Every new car sold in the European Union must include a d... by vincnetas on Wednesday July 08, 2026 @03:39AM (#48828800)
You can use OBD2 dongle to change default setting of lane assist to be off by default (after car starts) And many more setting that are decided for you as if you were using a rental car not your own. Like always reseting air conditioner to 22C after starting a car. God dammit i want 20C. Let it stay like that when i start a car.

> You can use OBD2 dongle to change default setting of lane assist

Colour me skeptical. ODBII is just a protocol; it knows nothing of the modules on your buses. I think you will find you need the dealer software. Tools exist that implement big chunks of that functionality, but since they are built on reverse-engineering, the price approaches the dealer software anyway.

The only place i found the Mercedes software was a paid forum that obscures the links. Getting the cracks working was a magic incantation. It's similar for VAG. They won't sell you the software if you're not a dealer.

You will not get there with a £40 ebay special. If you can, please share what works, it will be of much interest to many.

You're correct that the dongle only facilitates the connection, but you don't need dealer software. I have an ODB dongle and a £20 (I think) app on my phone which lets me change a _ton_ of settings on my BMW which aren't available in any in-car menus.
Re:Every new car sold in the European Union must include a d... by psd1 on Thursday July 09, 2026 @04:21AM (#48842596)
What app?
Re:Every new car sold in the European Union must include a d... by glitchcrab on Thursday July 09, 2026 @04:46AM (#48842846)
Bimmercode lets you do coding (it's very powerful and you can easily mess up your car so you have to be very careful with it), and Bimmerlink lets you read fault codes etc.
Re:Every new car sold in the European Union must include a d... by psd1 on Thursday July 09, 2026 @06:07AM (#48843468)
Does it label the fields, or are you following forum instructions to write 0x01 to module 76 channel 004?
Re:Every new car sold in the European Union must include a d... by glitchcrab on Thursday July 09, 2026 @06:13AM (#48843504)
Safer settings are exposed with decent labels, but you can also use the advanced mode which is much more low-level, akin to what you described.
Re:Every new car sold in the European Union must include a d... by psd1 on Friday July 10, 2026 @05:50AM (#48857870)
Thanks, i learned something new. I think we're both right by degree. That app is more functional than anything I've found, but there comes a point where you need someone to tell you the modules and fields or you risk bricking your car.
Re:Every new car sold in the European Union must include a d... by glitchcrab on Friday July 10, 2026 @06:23AM (#48858049)
Oh for sure, but you can do a lot of things without ever touching the advanced coding section. It's definitely worth being cautious though - as you say you can definitely brick your car with it if you're just YOLOing your way through it. It does back up the module configuration prior to writing the update though so you do have a safety net.

not affiliated. have used ODB eleven on my vw eup (2021). They have curious payment strategy. Basically you buy tokens and then use them for each enable/disable operation.

For VW cars, that has been severely limited as well from 2024 with SFD2, which requires a token from VW. Quite sad really.

"caused me to start ignoring the speeding alarm within"

Not sure if this has ever been implemented but I know from my time in automotive that there was the idea to exchange driving data with the insurer. If this becomes reality ignoring speed limits could increase your insurance premiums.

What's the legal status of 'your' car spying on you if its a company or private lease? After all its legally not yours, and they can put a lot of things in the contract.
Re:Every new car sold in the European Union must include a d... by frereubu on Wednesday July 08, 2026 @10:25AM (#48832397)
The issue is that currently it often gets those speed limits wrong - as one of the parent comments said, when using adaptive cruise control I would often find the car slowing down from 70 to 50 in the middle of the motorway which is really dangerous. Thankfully you're able to turn off that part of ACC and it stays off, but it's on by default.
Re:Every new car sold in the European Union must include a d... by netfortius on Wednesday July 08, 2026 @11:03AM (#48832906)
This reminds me of the time I was (still working) in the US, for one of the big insurers, and we were researching ways to detect on which side of the car our client gets in, to assume (if from the right, in the US) that our app shall not trigger the "driver" mode, thus all the consequences if being assumed responsible. Fun times.
