How does Gen1 decide what roads and when highway assist is available?

[smashweights]

Took my first decently long trip out into the country in my '22 R1T. In my boredom, I couldn't help but wonder how the Gen1 highway assist decides when it's available or not. I was mainly on state routes, much of the time it was 4 lane divided highways with clear lane lines and highway assist would pop up sporadically but only let me use it for like 20-30 seconds. This road was nearly 4 miles of straight like this and I got no highway assist.

The only semi consistent thing I could find was if the next intersection was a "freeway" type with an exit lane and a merge on lane it would work until I passed that. My wife's 2025 Hyundai will try on any road, but isn't the best on back roads or poorly marked roads whereas the Rivian won't even attempt to work.

TL: DR - what is holding back Gen1 from lane keep on most roads?

Gen 1 relies on geofenced, pre-mapped areas of highway, but even then that is also highly reliant on the maps being accurate and your precision GPS also working perfectly reliably so the system can be sure you are where it thinks you are. It's probably one of the worst implementations of ADAS I've ever seen.

What's keeping it back is that Rivian has no interest in further development on Gen 1 and all resources are now focused on their Autonomy + platform. In all honesty, I think they'd prefer to pretend Gen 1 doesn't exist.

Technically I *think* it's possible for them to open up the system to simply use the cameras to allow lane centering on any road, but as I said they have no desire to put any resources into Gen 1 development. RJ himself called Gen 1 an evolutionary dead end (or something to that effect).

Not going to use my Gen1 system any more at least on curvy roads, it's straight up unsafe on high speed turns veering out of lane centers and going to close to others mid turns

I have an answer for that!!!!

And if said stretch of road has been reshaped after mapping, the feature is NLA. If you want better autonomy in your gen1, Comma is the only answer.

I'm glad you said it, I'm done being in trouble

I'm tired of being accused of being a paid shill.

Wait, you make more than me?

(Yes, I am joking)

And I am not a Comma user. I have no horse in this race. I just tell it like it is.

I count the happy users as payment myself. Makes me feel great about the project.

You are what you are!! Haha

Speaking of which, I need to buy the comma. Enough people have proven it’s value, reliability, in our Riv’s..

EDIT: And the team is very patient and helpful, even when folks, just do NOT RTFM.

I don't even care about lane centering. Just activate the cruise control, every single time I ask for it. The rental Nissan Rouge would do this every time I ask it to do to. Mine refuses to engage cruise below 20 mph, but then sometimes it would, at the same exact spot. It must be the pollen in the air or humidity.

You can engage below 20mph as long as you have a vehicle in front of you and clear lane lines visible. In the latest update rivian claims they lowered the minimum engagement speed to 5mph, but it doesn't seem to be working as intended.

I have noticed the vehicle in front part, but even that is not consistent.

It also lets me engage while fully stopped with car in front, sometimes.

Yeah I've seen the Comma suggestions just wish Rivian would surprise us with the basic lane keep assist most mainstream OEMs have nowadays
