I do, but there are times where a break is very nice on long trips. Like, driving straight thru from the Willamette Valley down to San Diego, being able to keep your hands off the wheel is actually very relaxing. Great for the bloodflow . I only showed the offroad thing to show capability. The only use I ever see there is if you're out by yourself and get hurt, you can maybe make it out to where others can reach/see you easier without as much "driving".

I love driving my truck, but this current trip Vancouver to Saskatchewan and back, really has me wishing more roads were Driver+ enabled.

Long and straight is the name of the game here.

What I have noticed tho, is when driving under a Driver+ enabled highway, for about 500 meters before the crossing and 500 meters after, my highway will have Driver+ as well. So while my road hasn't been mapped, the system was fully functional, and understood all the merges etc until I crossed out of the geofencing and it made me take control.

So my hot take is Driver+ is capable of the same or similar comma driving, Rivian just needs to open the fence to allow it in every area. Which, unfortunately won't happen.

On the default OpenPilot software, it's as @godfodder0901 said; the standard Rivian ACC is used for throttle-control, so the behavior on the steering wheel scroll wheels / buttons is the same.

Switching to the SunnyPilot software requires the upgrade harness in order to keep those steering wheel controls working. There is a branch of SunnyPilot which is now outdated (as of like a week ago, so it's still highly usable), which lets you adjust speed & follow settings on the 3X itself.

The side-view cameras work on all versions of OpenPilot/SunyPilot. Blind-Spot-Monitoring also works, however an auto-merge will not be prevented unless you're on SunnyPilot + Upgrade Harness.

Newbie here - with SunnyPilot being recently outdated (I assume because the main branch of OpenPilot got an update), does that mean if you want longitudinal control you’ll always have to run the outdated version of SunnyPilot or will there be new “versions” of SunnyPilot.

It is not Sunnypilot that is outdated. Lukas Loetkolben, the man responsible for making all this happen for the Rivian, created a special fork of Sunnypilot that includes on screen buttons for speed control max setting. He is not supporting the fork going forward, so it is what it is for now. The build was to give folks a taste of the longitudinal control without having the added longitudinal harness. It violates some of the safety protocols by having you interact with the screen, so it's not something that would ever be a supported feature.

Sunnypilot is continually being worked on and supported.

Makes sense, thank you for the explanation.

I’m on the fence between using the stock Comma harness and the upgraded harness for SunnyPilot. I will only be using it on highways.

For this use case specifically, is it less reliable or less smooth with the stock harness/Rivian longitudinal control when compared to Comma longitudinal control?

I’m ok with losing out on the extra functions of the upgraded harness/SunnyPilot, mainly interested to know if it would be a worse experience for highways.

You can get a €100 discount if you buy both harness from Xnor at time of purchase. I went that route and skipped the harness from Comma direct.

The comma harness was $99 and to add longitudinal control would cost €349 additional + shipping.

I just bit the bullet and bought it all for €424 + shipping. Buy once, cry once and hopefully install only once.

I will say, adding the longitudinal harness later is not the same undertaking as the main harness, so if you wanted to wait and see, it wouldn't be a frustrating experience later. For anyone considering this approach, the only thing I would do is grab an additional USB C 3.2 cable and run it along with the ODB USB cable that comes with the comma. This would make adding the long harness super quick only needing to access the footwell area.

As for the experience between the sunnypilot long and Rivian ACC that is something that each person would find different depending on what they expect and are comfortable with in their normal traffic flow. Currently, the stop/follow distance is a little further out than Rivian's on the closest settings. For me, this is a problem in traffic where people will keep jumping in front of me, however, they do that even with Rivian's acc. Like the Rivian, you can overtake throttle control and close up gaps manually with the pedal - but it's a little janky until the pedal position reaches the current speed position, specifically for Rivian. That is an issue that is being worked on. That's the beauty of open source here, continually improving.

Done. I just put an order in for comma and the harness.

off topic - I hope you're enjoying the sunshade we tested. I have some upgrades on order to help both of us with keeping the sunshade stable at 80 mph with all the windows down.

I think the discount is gone. the longtitude upgrade is price is at 349 now with no bundle discount

If you're seeing 349€ then you selected the incorrect version to pair with Lukas' harness. Be sure to open the drop down and select for the Loetkolben Harness. It defaults to the comma harness variant.

thank you. Ok, i'm jumping back on the comma. This time I'm getting Lukas harness instead of the one from Comma which caused all kind of errors with my R1s

I have just basic Comma and is great for my needs. i really like the latest version of FSD on 24 M3. However still too much AI deciding how fast to drive and doing what I hate others to do on interstate. Speed up / slow down repeat. Comma is perfect, set it and forget it.

my only issue is the damn adhesive to the 8 degree mount keeps unsticking in heat. will keep working on that.

Are you using a 3-d printed mount? I've heard that can be an issue with those.

Its the angle mount that comma sent

Did you clean the windshield with the alcohol wipe and let it cure 48 hours?

Looks like the sale ends at 10am Pacific tomorrow, Monday, July 7th.
