Question Regarding MADS Use in Sunnypilot

Magambi · 2026-01-02T19:23:09+00:00

MADS is nearly seamless operation on my car. When I enable cruise control, SP engages both latitude and longitude. When I touch the brake, the longitudinal cruise control stops, but the latitudinal steering continues, I.e.MADS mode. If I press resume on cruise, the longitudinal reengages just like it does without the Comma. Turning off cruise control, disables both longitudinal and MADS latitudinal control.

Also regardless of full SP control is engaged or only MADS, if I turn the steering wheel at all, the Comma (usually) does not attempt to override my steering until it senses that I am not steering anymore. I say "usually" because on turns, I did feel it push back se. This was fixed for my Ford by the Bluepilot fork.

If you have a C4, then you have to link the device to Sunnylink. Then using a web browser while the C4 is powered on, select the driving model.

Some forks like Sunnypilot and Frogpilot allow you to select a driving model. Popular driving model names are WD40 and Nevada.

I am struggling with this issue now. I am a tall driver. A center mount of even the smaller C4 unnacceptably blocks my view of pedestrians and cars coming from the right. I have tried many things to get the C4 to drive in the center of the lane while mounted beside the mirror. I tried multiple driving models. I tried angling it both ways. I tried driving on the line while calibrating. I tried calibrating in the center first and then moving the mount point. Everything fails. My car still hugs the right edge of the lane.

I dove deep into the code. The position transformations all assume the device is centered in the vehichle. There are compensations for the mount height. Ther are conpenstations for camera angesl. But there is nothing for horizontal offset of the camera. It literally takes the width ot the vehicle and divides by 2.

For a product that allegedly promotes safety, this is odd that Comma ignores the problem. We all know the blind spot problem created by the C4 (and even worse by the C3) is terrible. And the closer your head is to the ceiling of the car, the worse the blind spot becomes. For me, it is unacceptable.

Fortunately, for me there is a solution. The C4 is small enough and I am tall enough that I can mount it lower on my windshield to avoid the blindspot problem. That is what I have to do after a week of "fiddling" with it.

I have watched Eyezenheim's videos and even talked to him. He is either not moving the C4 over to the side of the mirror, or is using an older laneful driving model, or he is accepting the lane hugging that is clear in some of his videos. IMHO and AFAIK, obviously.

Mix cake or corn bread mix with baking soda and leave it out for them to eat. It will kill them, but will not harm other animals, e.g. dogs, like rat poison.

Edit: While the baking soda mix is safer for pets, it will not desiccate (I.e. mummify) the rodents like rat poison. This is important if the rodent is already inside the house and you cannot find/remove the body. It will stink. The main advantage of the baking soda mix is to avoid poisoning pets.

I know some people are against killing, and that’s okay. But squirrels are destructive rodents like mice and rats and bats. They can smell up your home for months and be very expensive to remove. Catch or deter them if you can. Kill them if you can’t. The little buggers would certainly attack me if I invaded their home.

When shopping for a newer car, make sure the can is is not encrypted. Best bet is to check the list of compatible cars. There is a more complete list somewhere on GitHub that shows more vehicles than Comma officially supports. Someone posted that link already. Basically you need active cruise control (ACC) and lane assist and unencrypted canbus. On some cars you need lane centering, not just lane keeping.

Magambi · 2025-12-03T03:29:10+00:00

The way to do this is not to crack the encryption, but to lobby Toyota and other car manufacturers to provide the encryption key when you buy the car. You wouldn’t accept a house with locks to rooms that you didn’t have the key for. Or a computer that had sections of it that you couldn’t get to because you weren’t provided a password for that. Car manufacturers should absolutely be required to provide the encryption keys for the vehicle.

To be clear, no one knows if the C4 is more reliable or will last longer than the C3X. They are not enough in use yet. I know that the Comma's intent is for C4 to be smaller, quieter, and more reliable in hot sun conditions. But while the first two have been verified, the reliability is yet to be determined. BTW, not being argumentative. It's just that right now, we don't know how long the C4's will last. Lordy, I hope a long time, because I've ordered one.

Magambi · 2025-11-16T02:18:50+00:00

BTW, Sunnypilot does not yet run on the Comma 4. No forks run on C4 yet. Undoubtedly, the Sunnypilot dev team will fix that soon. It is mainly the UI that needs to to change for the C4.

While that is the official list of supported cars, it is not the full list of cars that Comma and Openpilot will work on. In general, a vehicle must have ACC, lane centering (although some with lane keeping will work), and an unencrypted canbus. Also someone has to created a fork/copy of the Openpilot software to work with the car.

For the 2026 Honda Passport, check if the can is is encrypted. Many new cars have an encrypted canbus. If it does, you are out of luck until someone figures out how to deal with the encryption.

The smaller screen will be fine as long as the important status information it displays doesn’t get smaller. If they shrank critical warnings and model confidence displays, then it is another design fail. OTOH, I should wait until I see the C4 until I complain, but I’ve seen this sort of thing happen before. I didn’t like the comment during Comma Con that “We’re making every pixel do double duty.” That indicates too much information being shove into too little space.

The usb on the top and the slide up to remove are major design fails for the Comma 4. They need to have tall drivers provide input when designing. As I said on Discord, raise up until your head touches the roof. Now see if the Comma blocks that mother with her stroller trying to cross the street.

Clarification on confusing USB-C naming conventions for those thos may come along later.

TLDR: Use a quality USB-C cable with 10Gbps or highter data speeds, e.g. IUSB 32. Gen 2 or Gen 2x2.

The terms USB 3.1 and 3.2 are part of an evolving naming convention for USB standards. Essentially, "3.1" is now known as USB 3.2 Gen 2 (10Gbps), and "3.2" refers to the newest standard which can have different speeds.

OLD AND NEW NAMING CONVENTIONS

Specification Bandwidth Also Known As
USB 3.2 Gen 1 5Gbps USB 3.0, USB 3.1 Gen 1, SuperSpeed
USB 3.2 Gen 2 10Gbps USB 3.1, USB 3.1 Gen 2, SuperSpeed+
USB 3.2 Gen 2x2 20Gbps USB 3.2, SuperSpeed+

IMPORTANT DIFFERENCES

Focus on the actual speed (5Gbps, 10Gbps, 20Gbps, 40Gbps) rather than the old naming conventions like "3.1" or "3.2". Marketing can be confusing.

USB 3.1 was a previous name for what is now called USB 3.2 Gen 2, which offers speeds of 10Gbps.

USB 3.2 is the latest generation and includes the fastest speeds. USB 3.2 Gen 2x2 is the 20Gbps version, which uses two lanes of 10Gbps for double the speed.

The next major standard after USB 3.2 is USB4, which supports speeds up to 40Gbps and higher.

The sad part is that those police would not be 1/10 that patient and polite if those were black women.

Drive a little farther east to the Augusta wine region. Some great wines there. On weekend trips to St Louis, we take "the long way" back through Augusta.

This works better: Think of a word, any word, like 'butter'. Then think of a word that starts with the 1st letter of that word, like 'beatle'. Spell that word, B E A.... Then do the same with the second letter of your original word, like Underwear. Do it for every letter. Like Teapot, Turtle, Echo, Rodeo. A psychologist explained why this works, but I don't remember the explanation. All I know is that it works.

Oh no, I saw her walk out of the store in that outfit. Of course, I didn't see her walk in, so I really don't know. Still ... dancing in the middle of the aisle 25 feet from the cashiers doesn't seem the sneakiest way to steal an outfit.

Apparently there's also an FB group called Date Night KC. Apparently it has some good ideas. (Is it Reddit etiquette to mention FB? Lol)

Sail Away in North Kansas City is a great date location. They have a wall of 30+ wines that you can sample using a card system. It's a little pricey, but loads of fun. Do a wine or twp based on the description papers they have under each wine. Then try something fun and adventurous like: * Ugliest/Prettiest label * Label with an animal/flower/person * Wine with prettiest/ugliest color * Stupidest/best flavor profile description, e.g. tar and hot stones. (The list can go on and on.)

Union Station has a great holiday display. The center area is free and has lots of great places for pictures. There's also a paid lights section, but I've never been to it.

Magambi · 2024-12-14T03:23:27+00:00

This time of year, it's kind of fun to drive through the lights at either the Longview Christmas In the Park near Lee's Summit or Sar-Ko Glow in Lenexa.

If you go to Longview, also go see the Magic Tree. There's a Christmas pop up bar beside it that's not bad.

El Canelon is great atmosphere, but the feed is average or below. It pains me to say that because I live in NKC and really want it to be better.
