Why 2025.26.30 update is a HUGE deal for Rivian Autonomy (Mobileye is dead)

[riverie]

On my drive today, about 200 miles of interstate, I felt the lane change was much smoother.
I agree that the vehicle wanders a little in the lane. Once or twice I felt it moved over as I passed a truck, but maybe that was expectation bias.

I did around 100 miles test today. And my observations are that the lane centering and lane recognition are much worse than Mobileye. The car couldn't keep the center of the lane and ran over the lane marking multiple times. On small curves, the car would just lose the lane centering ability. And also on a straight highway with no cars on either side and a lead car several hundred feet in the front, the solid blue marking indicating the car's trajectory would be showing an inverted J curve path even though the lane was just a straight line. It has become so unreliable that I would not use this at all. I guess we are just beta testing stuff for Rivian at this point and this is not ready for prime time at all.

but I don't think they're very motivated to try, either.

Is it motivation or current priority? You may be correct, but R2 isn't likely to have any Mobileye technology, why would it since Rivian are migrating to the in-house solution and Mobileye would be extra cost they don't want. This means Rivian's priority at the moment has to be on developing the in-house solution using the R1 G2 platform and all the collected data from these vehicles in order to put their best foot forward when R2 launches and starts getting reviews.

Just my 2c.

Seems like a distinction without a difference to me. They're neither motivated, nor is it their priority, to work on a generation of vehicle that uses severely outdated Mobileye hardware that is a. no longer going to be included or, b. included on vehicles that have an alternative proprietary ADAS tech stack.

I'm also not convinced they even have the ability to provide any meaningful updates to Driver+, other than maybe adding more pre-mapped areas, simply because the Mobileye hardware is so locked down.

This. This is the real issue

I personally think they do. They have touted their compute stack many times (pre-Gen 2 anyway) and seem to only need Mobile-Eye for the sensor stack. Though, they do advertise 11 cameras (not including Mobile-Eye) and use exactly 0 of them for Driver+... They have also talked about 'sensor-fusion' making it seems as though they have some capability to decouple from the full Mobile-Eye stack.

Still waiting on 2025.26.30

It seems Rivian originally believed they could integrate the additional cameras into the Mobileye system. However, the version of Mobileye they used in the R1—the EyeQ4 Mid—doesn’t support extra sensors or cameras and relies entirely on the single windshield-mounted unit. On top of that, Gen 1 vehicles lack any custom compute of their own, making them fully dependent on Mobileye. My guess is they hoped to find a workaround or “hack” the system, but after several years of trying without success, they eventually abandoned the idea.

Great write-up here if you haven't seen it:

TLDR summary is:

Rivian spent the last 3 years trying to connect a 360° sensor suite into an incompatible perception processor. So, they upgraded Gen2 to Mobileye's new processor so that they can start providing autonomy until they launched their own solution. We have evidence to support this;

• For Gen1 autonomy, it's been reported that "they 'just couldn’t make it work'".
• For Gen2-exclusive RAP+ advertised features, they match what Mobileye has for EyeQ5:
  • Full Surround High-Definition Vision Perception = 360° traffic render in your dashboard
  • Autonomous Lane Changes = Lane Change on Command
  • Highway and Traffic Jam Assist = Enhanced Highway Assist

Own Gen2 R1S with updated software. Found the updates to be a very mixed bag. Some roads it works well. Other roads (4 lane highways with median) it doesn’t work hands off. Putting the turn signal on results in a very quick lane change which causes me to keep my hands on the wheel concerned it is turning way, way too quickly to the next lane.

We own a Cadillac Escalade with Super Cruise. That system is vastly superior to Rivian’s, even with the most recent update. We use that feature on long road trips. Rivian’s system is not stable enough to rely upon at this point. What I don’t know is whether GM’s system works better because they have mapped roads which Rivian has not or whether it’s just a combination of cameras and lidar sensors on the GM gas guzzling monster.

One thing, and I know this is kind of stupid, the GM system changes the color of the upper portion of the wheel to Green (aka, it’s working), then Blue when it’s disconnecting for whatever reason followed by butt shaking. Yeah, you can see this little icon in the speedometer area on the Rivian with two little tiny hands, but, seriously guys at Rivian—is this the best you got?

Kind of silly that good ole’ GM can make this work very well and the ‘advanced’ Rivian which is a software company is still lagging.

Yeah, Super Cruise is widely regarded as one of the best ADAS systems available, in part due to their excellent feedback mechanisms. And for all the autofellatio Rivian performs for RAP+, it's still one of the worst on the market.

Very interesting sleuthing results, @mpshizzle. Thank you for piecing that together.

I am relieved that I'm not alone in finding that the update made the highway assist a lot different. I do not like it nearly as much now--it has been leaving the lane on me, sometimes moving TOWARD traffic when there is more room on the other side. It definitely needs some work and feels like a step backwards. I certainly hope this is about moving to a new system and hopefully the next iteration will be better.

It's hard for me to be too upset about this since I generally like driving and didn't buy my R1S for any highway assist technology. I really just want them to add a valet feature!
