Are adaptive high beams more aggressive now?

[peakbaggersanonymous]

Has anyone else noticed the adaptive high beams activate much more frequently in situations where they just aren't called for? This was driving at dusk in rush hour traffic with other cars everywhere in both directions. Where in the world would it even be putting high beams in this case?

Also, why is the method to deactivate adaptive high beams so inconsistent? Sometimes when they are on (blue icon), pushing the light stalk returns to normal headlights. Other times pushing the stalk just turns on full brights and I end up blinding the people in front of me. Feels like there is still more work needed here to fine tune the SW.

I don’t know have any concerns about them. I can see clearly and no one in front of me or coming towards me seems to have a problem

Gen2? The adaptive brights are pretty good about not illuminating other vehicles.

Like Dark-Fx is alluding to, by all accounts, the actual adaptive headlights in gen 2 are pretty good with auto detection. Gen 1's auto high beams on the other hand has always been inconsistent and easily fooled. One rainy night in slow crawling traffic, I was right behind a silver Prius and my T was flip flopping the highs repeatedly. Disabled the function immediately and left it disabled. To me, if enabled, the function should only be auto-off only if highs were turned on manually to begin with. It should never be auto-on if it can't see and interpret the real world correctly.

it’s is a Gen2 that’s the point of the adaptive high beams to come on as much as possible and filter out illuminating other vehicles.

I assume deactivating is the same procedure as Gen1, if the highbeams are actively on pulling back on the stalk turns them off and deactivates auto high beams. If they are off, but in auto mode, pulling back will flash the high beams until the stalk is released and turn off auto high beams.

Yep, I noticed they seem to activate more frequently, and switch between on/off more often. Which is good imo, if safe to do so and nobody is getting blinded, why not run high beams all the time?

I'm also unsure what the "deactivate" behavior is. For the first time since owning the truck, I flashed someone yesterday to yield right of way at a stop sign, and noticed that the headlights no longer went back to adaptive during that drive. Sometimes, it's on auto, sometimes not, and every once in a while I have to fiddle with the rocker switch to get them back on.

My Gen2 seems to work OK until I am on a lonely dark two lane highway.
Cars are OK but virtually all big rigs are flashing high beams to get me to turn them down.

tl;dr When there is not an ‘A‘ in the headlight icon, pushing the stalk switches between low beam and full always-on high beam. When there is an ‘A’ in the headlight icon, pushing the stalk switches between low beam and adaptive high beam.

We were experimenting with this after my husband tripped across the always-on high beams by accident. It turns out the Gen2 turn signal stalk push action is an undocumented (I didn’t see this mentioned in the manual using the search) speed-dependent feature, from what I can tell. If you’re driving slowly enough that the adaptive lights are NOT activated (25mph to turn on but once on you need to slow to 20mph to turn off, IIRC) then pushing the stalk away from you turns on the non-adaptive high beams, indicated on the driver’s display by a blue high beam light icon without an ‘A’ inside. They will stay manually activated from that point on during your drive unless you manually deactivate them by pushing the stalk away from you again. This can be handy since on some dirt roads with no cars around, the adaptive high beams actually do a worse job of lighting the road ahead as the system falsely identifies some things ahead as objects which should not be blinded.

On the other hand, pushing away from you when the adaptive lights are on will switch between low beams and adaptive high beams but there is no way to force the high beams on without pulling the stalk towards you and holding it.

In general, I find Rivian’s logic around some controls or triggers to be too complicated. Using the same control or action to do different things based on some other criteria can be frustrating.

Kind of like opening a rear door or tailgate turns on interior lights in some conditions but does NOT turn on the interior lights in certain other conditions. This despite selecting the setting to turn the interior lights on when opening a door. It’s kind of embarrassing when opening a door for a passenger at night elicits a question like, “Are your inside lights broken?”

In both of those scenarios for disabling, you end up flashing the car in front If you unintentionally.

I got flashed by big rigs constantly on a 2 lane road on a recent trip. I guess the Rivian isn’t good at detecting semis and turning off those segments?

I’m going to play around with the speed aspect now. Hard to believe there would also be a speed dependence that changes the behavior. That’s just overly complicated!

Here’s what‘s in the Gen 2 manual.

 

[Dark-Fx]

Push the stalk forward to deactivate and reactivate the auto high-beams, but it has to be done while driving above 25 mph. Otherwise it just activates the normal high beams.

I'm still confused on whether OP has gen 1 *AUTOMATIC* headlights or gen 2 *ADAPTIVE* headlights. I think auto not adaptive. I wish people would put their gen/year in the vehicle info.

My auto headlights, gen 1, have been noticeably more aggressive towards high lately. Not terrible, never blinding anyone, but flashing too much so it may confuse drivers.

TLDR: 10000% feel you on this, I have a Gen 2 - '25 R1S. Don't get me wrong, it APPEARS like they work well as the driver, however the jury is not out for benefits and functionality.

I get flashed on the interstate constantly when the adaptive brights are on, which often I end up turning them off. Sometimes turning them off very much helps too, as the vehicle lights brighten the actual road in front of me vs. the vast forest and outer space (where I am clearly not driving).

Separately, I noticed the other week the inconsistency of turning them off too. I went to push the stalk forward to disengage and was so confused. I flashed everyone on the road 5-6 times trying to figure out what was happening to realize I was getting closer to the car in front of me while troubleshooting, appearing like a road rager tailing someone and flashing my brights. Went into the UI and turned off the setting and embarrassingly slowed down.
