Blue Cruise Dangerous Experience!

[jpiazza67]

BC1.0 has been nice but it’s not trustworthy and it’s dangerous. I was driving back from Baltimore to Raleigh 10 days ago and BC canceled, immediately terminating steering control, skipping past drive assist hands on the wheel part. That is a crazy dangerous condition that should NEVER happen. I would have been toast if the error occurred midway though a bend in the highway… being ready to take the wheel is not enough time to prevent a crash with an error like this in a turn. I seriously question the use of auto pilot tech by manufacturers. What happened to fail safe systems?

I've never seen it shutdown entirely. Even on hands-on mode when it freaks out it still steers for a few seconds. This is ADAS L2, aka, you're in full control regardless of how much assistance it provides at times.

I haven't ever had this happen, but when driving in hands free mode especially around curves I usually have my hand ready to take control just in case of a situation like this. Theres only one time (in probably about 5000 miles of handfree driving) that I have seen bluecruise do something very dangerous. It was when I was going under an overpass, it turned quickly off the road, but I was prepared to take over and correct it.

That being said, it would be nice if there was some indication that bluecruise might disengage before it does.

I’ve had a similar experience for the past 6 months I’ve owned the car and have been using BC, except for this one time. It only takes one time for a disaster though. I’ve had it go quickly out of drive assist as you’re saying, that is why we need to remain ready but this was an instance where it was completely skipped. Nothing would have prevented a crash if it happened in a turn.

My worse case is when it sees a turn lane in lane centering mode and tries to yeet the whole car into the turn lane at 60 mph. One time it shot completely into the oncoming lane before it gave up. So beware of sharp angled white lines.

Yeah, this is the worst thing is does, always trying to take poorly marked lane splits on both left and right sides.

*You* would be responsible for preventing any crash, no matter how BC was / was not performing. This is the definition of L2 ADAS. Do not conflate BC with auto-pilot or "self-driving", it's not that and never pretended to be.

That’s happened to me on a couple of occasions. Went straight from hands-free to lane keeping. You get 3 deep tones to alert you through the sound system and the screen briefly changes to hands-on lane centering before reverting to just lane keeping. It is disconcerting the first time.

Honestly, this feels extremely alarmist. I have had it completely cut out and bypass drive assist before, it chimes and I responded as I should have since I am the one controlling the vehicle. I will say that again. I AM THE ONE IN COMMAND. If you think it was "crazy dangerous" I question how much attention you actually had at the moment it canceled. You are to be able to take over at any time, for any reason. If you are caught off guard, then you're using BC wrong from the start.

You're still supposed to pay attention to what it's doing, this sounds like driver fault.

The system is designed to alert you if your hands aren't on the wheel. If your hands aren't already on the wheel it will make all kinds of noise to get your attention. If your hands ARE on the wheel it will just do the single chime and say "cancelled".

In my experience with the car it will get that wrong and think my hands are on the wheel, when they're not actually 10-15% of the time. But in either case the steering wheel will never just let go back to center. It will maintain it's current steering angle for 10 seconds or so while you retake control. So even if it happens on a curve, it won't yeet you over into the next lane.

(unless there's a random marking on the freeway that it thinks is the lane, which isn't too common)

Tesla on the other hand, when you disengage autopilot by tapping on the brakes will very suddenly just let go of the steering, and that is a bit alarming if you're not used to it

Curious Lee if at the time there were painted dashed lines to mark the exit? For some reason in Ontario the lane marking completely disappear for highway exits and BC *always* wants to follow the curve towards the exit. Not sure why the default wouldn't be to follow the left line marking...you know, the one that's still there?

Anyway, I'm always ready now.

Yeah, this is probably why we don't get hands free on anything other than full freeways. Hopefully they figure that out at some point.

Wonder if the current hardware could eventually add stop light detection? But that's a different topic for sure.

No, in Wisconsin turn lanes and exit lanes are wide open gaps, no dashed lines:

In that situation you better hold on because you have about a 50% chance of getting yeeted left or right randomly like a Plinko board.

Another major issue I have is with the white taper lines coming back over after intersections. It will want to follow the white line and send you over the yellow line:

That is the most dangerous one because you can quickly end up in the oncoming lane if you don't have a firm grip.

I use mine frequently (Ann Arbor to Toledo commute).
It works correctly 99%of the time. Only twice, out of many hundreds of trips, did it skip the normal warning process and completely disengage. In these two instances it shut off completely, with no lane keeping or anything.

It was definitely starting, because the car drifted right and hit the rumble strips. I pay pretty close attention, but as luck would have it, I was fussing with the radio during one of the shutdowns. That said, I’ve discerned no pattern as to time or place for the shutdowns, and I remain pretty happy with the overall blue cruise experience.

I really didn’t want BlueCruise when I got the car in February of 2021, but now I’m addicted to it like heroin. In fact, I recently cancelled my Blazer EV order because I couldn’t get Super Cruise until the SS is manufactured, so I shifted to the Lyriq.
