Blue Cruise Dangerous Experience!

[Mach-Lee]

My worst experience was the system following the old lines.
Blue cruise never disengaged but did change 3 lanes in about 10 seconds.

The issue happened as we went through a prior construction zone, new lane lines had bee freshly painted. The old lines had been sand blasted away.

Unfortunately Blue Cruise followed the sand blasted markings instead of the nice bright and very straight lines.

I’ve had the same scenario before as well. The road curves, but the old erased construction line keeps going straight. About 25% of the time it will want to follow the erased lane and go straight for the ditch. So that’s another place I have to keep my hand ready for sure.

Whether it follows the line definitely has to do with contrast. If the sun angle is just right, or the erased line is filled with water, it will be more likely to get followed.

Other high-contrast markings like pavement grooves and joints can also mess with it because it thinks it’s a road edge.

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.

Yes I ALWAYS want final say. The latest version will slow on corners (sometimes below speed limit) so if I am pressing the go pedal, keep going, don't still try to slow down and brake check guy behind me. I have to keep pressing go pedal harder to over ride it.

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?

My friend's dad is the forensic pathologist on 2 Tesla self driving cases. His advice DON'T USE SELF DRIVING MODE!

This happens to me somewhat frequently and I agree it is very dangerous. On a recent road trip when driving along swirly I-70 through Colorado, Hands Free cancelled two different times when in sharp turns. Luckily no one was beside me the first time as the car immediately swerved into the fast lane from the slow lane. The second time it happened and I was already nervous so I had been doing "hands on" during Hands Free and saved it.

More recently though on a trip in the city here, I was using Hands free at midday on an interstate with light traffic. At three different underpasses almost in a row, Hands free cancelled out of the blue and luckily these were straight sections of the road. I'm thinking that the angle of the sun and the high contrast perpendicular shadows on the road from the overpass was making it so the painted lines could not be seen well and it just cancelled? WTF?

I don't think needing to take over immediately when it disengages is a safety issue. It's an expectation. But the lack of an audible notification to do so is very much a safety issue.

It will squawk at me if I'm taking a drink from a can to watch the road (which I am), but it won't make a sound if it disengages (a situation of much greater need). The only way you are notified is on the IPC. The only time I ever look at the IPC is if I see a cop and care about my exact speed. Otherwise, I'm watching the road, checking my mirrors and paying attention to driving. The things you're supposed to be doing. You shouldn't be required to be staring at a screen to know that the car needs you to take complete control back.

On my last trip, I experienced a bunch of half black / half white lines. Apparently this is supposed to help the white lines stand out. BC doesn't think so.

Interesting... In my state (Utah) the interstates make extensive use of the black/white stripes and in my experience BC actually works almost perfectly.

Well....I mean.. as well as it works under ideal conditions. BC 1.0 is a bit wandery even in the best conditions

I believe Utah is where we had some issues, in bright early morning sun. Or maybe that was New Mexico...

I will give that to you. I've found the lines work extremely well. But driving south into the morning sun on the other hand, BC reacts like this:

There is one aspect that I find unsafe which I think should be an easy fix. When in cruise control say at 100 kph and you come up on a curve the vehicle maintains the speed even though you are assisting in the curve. You have to tap out the speed in order to safely negotiate the curve.
What I cannot fathom is why the system cannot 'see' the curve through the map and gps and slow the speed down to a reasonable pace to negotiate the curve safely.

No thanks. I'll decide what speed is appropriate if I'm steering.

"Hands Free" driving actually means, always have "One Thumb, and One Finger" hovering below the wheel, to avoid any catastrophe.

Depends on the curve. I have several on my daily commute that are banked, so easy to negotiate at speed unless road conditions are poor, but my car still slows when approaching them. I know to watch for when it does that, and if I disagree with its slowing, can put my foot on the accelerator enough to maintain speed, but don't mind the car slowing, since that may help me someday in the future on less familiar roads. It isn't a drastic change of speed, but more in line with what many more cautious drivers would do approaching an unfamiliar curve. I assume that feature gets shut off with turning off speed limit sign reading and adjustments.

This exact feature has already been added to BlueCrusie 1.2, it's called Predictive Speed Assist. You will get this feature when your car downloads BlueCruise 1.3.

EDIT: I see you have a 2023, so you might just need to turn Predictive Speed Assist on in the settings.

It's better than nothing, but people that have it on 2023 vehicles often complain that it slows down too much on curves, so that's the downside of it. Too conservative with no adjustment.
