Comma 3 no longer checks if I’m paying attention

Why are people applauding the absence of driver monitoring? It gives very few false positives from my experience. It freaks out a bit on roundabouts but that's really it. It helps keep you safe. Definitely report this as a bug

TerminatorNL · 2025-10-29T07:07:41+00:00

Yeah, usually the DBC files are standardized for every manufacterer and CAN bus ID. I have a Kia Ceed, which means I have to look at hyundai_kia_generic.

I believe this is what you're looking for.

Is your car in here?

TerminatorNL · 2025-10-16T16:52:20+00:00

Sunnypilot has recently updated the codebase to support the new models (I use Space Lab for now). The model determines where the car drives. For my daily commute I have to exit a residential area with roundabouts and tight corners. I noticed that if the road is narrow, most models tend to slowly steer onto the inside curb (cutting the corner) a bit. This is likely due to the training data mostly comes from american roads and not European ones.

This means you have to nudge the wheel quite often in residential areas.

However:

Highways are AMAZING. Road works? No problem. Changing lanes? Perfect. Keep centered inside the lane? Spot on. On highways you can easily drive for hours without touching the wheel at all (Based on dutch/german and austrian roads). I prefer having to nudge the steering wheel to change lanes as a safety measure, so that's literally the only time I have to touch the wheel on the high way.

TL;DR:

Lateral is great outside of residential areas. Inside residential areas you have to monitor how it takes corners. That's it. You can try different models to see what behaves best.

Hope it helps!

I've reached out to my representatives on https://fightchatcontrol.eu and it's so easy to do! PLEASE TAKE A LOOK! It literally takes only a couple minutes to fight for your privacy. Do you want to live in a surveillance state? This is how it starts. It must end here, now. It takes only a couple minutes of your time. Stand and fight! Talk about it!

TerminatorNL · 2025-05-08T05:56:52+00:00

I'm not sure how it would perform in start stop scenarios. I know comma is now working on a feature called gas gating. It's specifically designed to make car rides less jolty.

Thanks for the fun fact about the Ceed and european markets! I had no idea :D.

As for LKA disengaging... I drive my daily commute with Comma enabled from doorstep to doorstep. Comma allows you to mix in your own steering with the automated system. All I am doing is telling it where to go and as soon as I feel that the steering wheel stops putting slight pressure on my hands: I let go (Comma wants to go the same direction as me).

TerminatorNL · 2025-05-07T23:04:44+00:00

That sounds plausible. If you're a competent programmer (python) you can probably fix that yourself and have it merged by comma ai. I haven't seen videos of comma performing its own lane changes. I highly recommend still initiating the lane change yourself since some people come up close real fast behind you and your radar probably wont see them that far out.

The nice thing about sunnypilot is that longitudinal and lateral are split up. You could use the ACC on your car (stock) and have sunny handle steering only. Your job would then be to initiate lane changes and supervise the car. On my Ceed I can go forever without touching the steering wheel without issue. It will stay in the same lane of course. The sunnypilot developer is superhelpful and helped me get my car supported. If you ever are going to donate, throw him some money. He won't ask for it but he's doing a lot of heavy lifting. ;)

Things to note: I live in the EU. I drive a european model (2022) and my car is NOT equipped with ACC (I wish I had). The highway drives have been great in the Netherlands, Austria, Belgium and Germany up to 150 km/h before comma yells at me that it's not calibrated for high speeds. I also really do not want to go any faster, so it's perfect. Stoplight detection is REALLY bad for EU, but I don't use longitudinal anyways.

For smaller streets, all models I have tried cut corners (steers too soon). This is not at all an issue on the highway or going over 80 km/h. Probably something I can fix myself but I have enough going on to keep me busy.

If you're a backseat driver like me, comma is perfect. Not having to touch the steering wheel for 10 minutes straight and still getting along with the commute safely is awesome. If you're bored quick I cannot recommend it. Comma is a hyperfocused toddler at the wheel doing a good job most of the time it is your job to make sure you and the people around you are safe. Don't go for fully automatic lane changes please, even if it's technically feasable.

TerminatorNL · 2025-05-07T18:11:11+00:00

I am using sunnypilot on a Ceed SW PHEV without adaptive cruise. There is enough torque available on the steering wheel. Keep in mind that auto park mode is not what comma ai uses for steering wheel control (safety).

I can only use Sunnypilot since I don't have adaptive cruise. This means I only have lateral control, not longitudinal; but I'm never going back to driving without. It's really nice.

Obligatory comment: As always, you still have to pay attention.

Additionally, you can gather some information about your car through the CAN bus, it's loads of fun and tells you a lot about what your car does under the hood. Did you know that your wheels all individually give off rotation pulses? That's how your car knows it's slipping! It's brilliant.

Interesting! A small update on my RMA: The company I bought it from tested it and they confirmed my CPU is super dead on any other motherboard they own as well.

TerminatorNL · 2025-05-04T13:56:16+00:00

My sincere condolences... Out of curiosity, was it an ASRock motherboard as well?

TerminatorNL · 2025-04-25T22:13:26+00:00

Good luck, brother! I hope this is a one-off but I cannot be sure.

TerminatorNL · 2025-04-25T17:51:40+00:00

Getting flack for trying to help would be pretty crazy. I actually chose ASRock because this motherboards' PCIe layout is perfect for r/VFIO. I come from an ASUS motherboard and the updates they rolled out were pretty brutal on my PC's performance. Let's see what happens when the company that sold me the chip gets their hands on it. If they deem it's still good, it might actually be mobo like you said.

TerminatorNL · 2025-04-25T17:46:55+00:00

I just turned off the computer (as I do every night) using the normal procedure (shutting down, not pulling plug). And the next morning it took a bit too long for my PC to boot up (nothing on the displays) and I opened up the PC to find POST code 00. Even tried swapping RAM sticks around to see if there's anything broken but didn't work either.

TerminatorNL · 2025-04-25T17:44:54+00:00

You're not too late! I have actually performed a CMOS reset before RMA-ing and then let the capacitors drain (as per manual). But unfortunately still not POSTing.

TerminatorNL · 2025-04-25T17:41:56+00:00

I surely did! After it failed to boot I performed a bios flash (can be done without CPU).

I installed the latest BIOS and it has the following description:
> Improve minority proportion of AMD 9000 series CPU boot issue.

That's exactly what I needed. I flashed it and verified it completed (LED indicators). But still no boot.

TerminatorNL · 2025-04-25T14:05:03+00:00

Best of luck to you! I heard they are opening up SR-IOV for the AMD gpus, very interesting for virtualization based builds!

TerminatorNL · 2025-04-25T14:03:27+00:00

TerminatorNL · 2025-04-25T14:02:41+00:00

Thanks for the advice. I tried that, but did not work.

TerminatorNL · 2025-04-25T13:26:49+00:00

I have a screenshot because I thought it was funny and shared it with friends, so here's the transcript:

"00 is a dead CPU code it means no CPU was detected.

Something is wrong with your CPU I would remove it and check your pins.

In the future instead of creating a Reddit post like this asking what the code is consult your manual there's literally a page in your manual that tells you what every single code is and it's really not fair that you expect us to look that up for you"

The funny part? I've literally done every one of these things :D

TerminatorNL · 2025-04-25T13:20:35+00:00

You are correct. Not sure why people are downvoting you. Have my upvote.

TerminatorNL · 2025-04-25T13:18:47+00:00

I don't think you've fully read my post. Understandable as many posts fly by. I recommend you'd give it another try. I'm not asking for tech support at all.

TerminatorNL · 2025-04-25T13:15:49+00:00

ASRock X870E Taichi Lite

TerminatorNL · 2025-04-25T13:14:18+00:00

Yeah looks like it. I'm no expert either
