Rivian AEB failure and crash

[Mark_AZR1T]

She turned left in front of us while driving straight in an intersection. The truck did NOTHING to help. In contrast, years ago, my Tesla prevented me going into an intersection when a red light runner was coming from the far right. And that was a 2019 with the old hardware and software. Am I sure a Tesla would prevent this? 90% yes. Certainly a Waymo would. AEB triggers warnings on occasion when I'm coming up behind a car too fast for its taste and far from crashing, but in this case, nothing.

I absolutely would never buy anything other than a Tesla today, if I didn't need a truck, and obviously, their truck is a shitshow.

This should do it...

That's a great wrap color!!

I happen to be a retired pilot. We had to take a checkride…...a proficiency check once a year for obvious reasons. 30-40% of that training and check was devoted to electronics and avionics failing. Electronics fail and should not be relied on 100%….ever. An airplane is required to have moderate redundancy for all its systems. I do not believe car manufacturers have that requirement. Use the electrical safety systems as supplemental, not concrete dependence on them is my best advice.

So is every accident we see with a Rivian where someone is t-boned a AEB failure? Accidents happen. Are you even sure AEB is SUPPOSED to work with drivers coming at you from the side?

Tesla has had many years to develop their software. And yes, it can help avoid collisions. I’ve seen the Wham Bam Tesla Cam videos.

What made you think you were in a Tesla? What did you not realize about Rivian’s software being less developed? Why didn’t you react and take over?

Makes me think it was too fast for you to react. Happens to the best drivers. I assume you weren’t looking away from the road. Even FSD Teslas get bent in accidents and occasionally cause them.

Wow, so many wild assumptions here. Like this...

you state safety is the most important

I absolutely did not, and didn't even use that word at all in this thread. Not once.

And then the assumptions that I somehow just didn't do anything and waited for the car to save my ass? WTF! I couldn't do that if I wanted to. I can't even stop turning my head to back up, because decades of driving have made me constantly scan my surroundings at all times in all the usual ways. I wouldn't be able to let even FSD be in control if I saw a threat, and have often mashed the pedal/steered at the same time as a driver assist system actually did work.

I wish you could have taken one of the times my AEB went off for no reason and put it towards preventing this accident instead. Since Rivian switched to their system the AEB has gone off at random several times, so I can say that there is probably some validity to your claim that it was deficient in this case.

Yeah, and in a cruel twist of irony, yesterday while driving, I had a FCW and mild application of brake, in a situation that was NOT going to be a collision. It's clear that Rivian's assist feature only works in a rear-end situation, not in anything more dangerous like this. While rear-end collisions are slightly more common, this is a close second but with far greater danger.

Who was driving, you or your Comma system?

I need to figure out how to read this from the logs, to be certain, but I think it was in lateral mode only (steering) and not longitudinal control. The Comma may have been able to help if I had that part on. This is a place I have been driving through for 15 years, a few times a week. I know the places where the speed control is likely to have an issue because of traffic, and often kick it off. I'd had the Comma do a lane change a few seconds before.

Now here's what I very well could have done differently, and I told my passenger this right away. The road goes from two lanes to three, but not a right turn lane. The right lane is where I needed to be in about a mile, but I changed into it with a three-blink signal and the Comma did it for me, as soon as it was possible. The person who hit me thought it was a right turn only lane and that I would be turning. Had I stayed in the middle lane, she would have stopped. Most often, I purposely do that and then change lanes later to make the right turn on the freeway a mile ahead. I'm not sure why I changed early that day, probably due to other traffic.

The Comma did record her admitting fault, so that's useful. Although I had also run the record function on my watch (audio) and on my glasses (video and audio). Now I need to figure out how to make sense of the logs to see what mode it was in.

Accidents suck, sorry you were involved in one. Thankfully nobody was hurt, and I'm certain you have insurance coverage on your Rivian. The only blame here should be the other driver, it's crazy out there!

 

[Eric9610]

So you have an aftermarket software running on your car… interesting omission in original post. Is it possible the Comma interfered with the safety system… highly possible and you will never know.

 

[mkhuffman]

It doesn't look totaled, but it might be. I hope not.

 

[SwampNut]

highly possible and you will never know.

Absolutely not possible and I already know, and have had an expert look over the logs. This has been tested and proven; the Rivian safety systems work on their own and can't be disabled, even if they wanted to.

Since I'm pretty sure I had its speed control disengaged, it is not relevant. Though if it had actually been in use, it may have prevented this.

After a drive yesterday, it became clear that there is suspension or wheel damage. I didn't notice at first that there's a gouge in the tire. At some speeds there's a wobble in the steering wheel, and there is a slight right pull. This means possible steering/suspension damage, but it could possibly just be the tire or wheel. My bet is now $25k and suspension damage.

My biggest fear/annoyance/anxiety is them giving me some shitbox rental for two months. I'm not sure how much I can demand a "like" replacement. I'm going to look around and see who is renting other EV trucks, that would be fun to sample for a while. If they have the repair done at Rivian themselves, they may or may not have a loaner, but it would be the SUV (Stupid Useless Vehicle).

Don't know the details on Comma, but it seems what I have heard is that it's pretty limited. Not sure why Rivian's getting the short end of the stick when it was not a stock setup.

100% sure you don’t have root access to Rivian OS. But nice try. None the less running aftermarket software violates Rivian TOS. And if I was the other persons lawyer I would use this against fault. I would not disclose you have this running to your insurance company.

You have no idea how the comma device works and you are just making things up out of thin air. It’s also amusing that point that I don’t have root access to the car’s software and then somehow claim that I am adding to or modifying its software. Hilarious.

That's a great wrap color!!

Thanks, we love it. This is another unknown in the insurance process and how they will get that replaced. It came from Twraps, so I guess I should ask him as I’m sure he has experienced this.

I assume AEB didn’t activate based on your memory (human and therefore flawed). Also, AEB activates at 7mph. Not sure what speed you were at. And… “hard acceleration” in an AEB situation can override AEB. Does comma have the ability to accelerate the Rivian?
