While on FSD and clearly marked roads, does your CT hug the left line and occasionally go over it?

[The Duke]

As per usual there aren't enough choices in this poll. The CT hugs the left in some cases, hugs the right in some cases, and centers in some cases. I am not sure what logic is driving the cases because it is an ML model. In the 'old days' we knew that it was moving away from semis, but now we are told by influencers that it moves away from 'dangerous driving'. The extra option I'd have added would be 'hugs left, right, and center under different scenarios'.

Choices in a poll are designed to get information. The choices are correct, I am avoiding the option you pose on purpose. The results will go to Tesla and give a clear statement of the problem. Adding your option muddies the conclusion, although it is often the case.

I guess I have to unvote then, because my Cybertruck does all 3. Perhaps the answers should have been 'yes' or 'no' since your question doesn't refer to anything but the first option.

Confirm mine hugs the left a lot, usually enough to be on the yellow line with the bumps bumping away under the tire, and enough to scare drivers on the other side of road, so I take over. On curves, it actually crosses the double yellow lines and goes into the other lane. It is as if it isn't calibrated for the turning behavior/radius of the CT yet. This all renders FSD unusable for me about 50% of the time.

...And there is no actual data being supplied, simply perception. How do we know that people who perceive left-hugging aren't just used to driving narrower vehicles and it has nothing to do with FSD tendencies but the actual vehicle width being wider than what they are accustomed to?

If would seem that if you want to prove something, you'll want to supply some tangible observations - likely via camera clips which then renders the entire poll moot.

IMO it occasionally gets too close to either side (the left being more often or more obvious, and it cuts left turns when there are multiple left turn lanes and the lane to the left is unoccupied).

And it does so for unknown reasons as well as for reasons I might (like leaving extra space between myself and a semi coming up beside). It does seem less bothered by nearby guardrails or dropoffs, being less likely than I am to keep extra distance from them. I don't have enough examples to say whether I'm happy with whether it keeps its distance or slows down when there's a vehicle on the shoulder and I'm in the right lane, although on one occasion it did less than I would have.

Getting too close to curbs and cutting corners occasionally are bad enough for me to take over; the rest is just not what I would do.

Vehicle width is one thing, but if the visualization display shows it not centered (and looking out the windows agrees), that's not just subjective as to whether it's too close to one side or another (the left side being more obvious to the driver).

the FSD visualization is illustrative, not definitive or exhaustive. It exists simply to make people more comfortable with the technology by providing a partial depiction of the data the truck is processing. Could simply be a visualization calibration issue.

Look, I'm not saying FSD is perfect - it's certainly not. My anecdotal observations still show issues making sharp right-hand turns (had to make the turn in two steps, not one continuous motion), still has challenges with wanting to run over center medians when making left-hand turns, still tends to prefer to ride bumpers of the vehicles in front and is quite poor at slowing down for slowing or stopped traffic - it seems to want to maintain speed until the last moment and then slam the regen and brakes vs a human driver encountering a slowing or stopped traffic situation who would let off the accelerator far earlier, regen longer, and coast into the situation at lower, safer, speeds often without needing any friction braking.

That said, all the items I mentioned above are provable with video clips. So if left-lane marker hugging is a thing, just post the videos. Easy peasy.

I'm not claiming the visualization is definitive. But I am saying that the vehicle should stay centered (and not cut lanes when turning, even if the lane cut into is unoccupied) unless there's a good reason not to stay centered. That goes both left and right even if left is more obvious to the driver, and it's obvious enough and decoupled enough with any discomfort I may have with a wider than previous vehicle that I'm happy it's real without going to the bother of pulling the SSD out, reviewing a bunch of video clips, and editing the interesting ones down to something short enough to post.

Mentions of rubbing curbs are also obvious more than just visually, and also indicative of not staying adequately centered.

FSD isn't SUPPOSED to be perfect yet, I understand that too; and IMO it's vastly better than nothing; so discussing its shortcomings can be done reasonably, since it is in the space between unusable and near-perfect. But being aware of the sorts of known situations where the need to take over may occur is not a bad thing.

MAYBE these things correlate with something manageable. I haven't gone around and wiped all my cameras with water and a clean microfiber cloth recently, although there's been enough rain that they shouldn't really need it, and the multiple camera display doesn't show any of them looking obscured or clouded. But in some cases, that might help. And a future feature where it tells you which camera may need cleaning might help.

Camera cleaning, sure. Avoiding direct sunlight, not sure what to do about that (hello radar).

I think what we're experiencing are artifacts associated with jamming the existing FSD models onto a vehicle platform in Cybertruck that has very different dimensions in length, width and mass (not to mention four wheel steering) that the other 6.5 million Tesla vehicles on the road. With only tens of thousands of Cybertrucks, and only a fraction of them using FSD regularly, it's going to be a minute before enough data is generated to create a Cybertruck-specific set of adaptations to the core FSD model - or maybe it's an entirely different model. That's for Tesla's AI engineers to figure out.

So if the model can't adequately judge width, stay closer to the left/driver's side and don't worry as much about the right side of the vehicle since there should be adequate clearance. But this creates other problems - like the left-turn issue hitting medians and needing a mid-corner correction on right-hand turns both of which I've experienced repeatedly.

It will get there, just need to keep feeding it data.

 

[rlhamil]

I think the cameras can handle direct sunlight better than one suspects, by adjusting the gain. Within limits, software can take care of that. Beyond that would require physical changes.

Further adjustments to the AI to cope with CT size do seem to be needed. That, and 4-wheel steering, and perhaps some other differences (braking distances?) may account for why FSD releases for CT seem mostly separate from those for other models. And of course the number of CTs out there is much lower than for other models, so data acquisition is slower.

Read the posts, they often say over the line.

I've read the posts, however there isn't a single video clip - in a vehicle that is always recording video while driving - that supports the assertions.

I'm not saying that it hasn't happened, but we fight a lot of FUD in this forum so having some evidence to support claims is helpful.

My Cybertruck often hugs or favors the left side of the lane. It also attempts when turning left to turn into an oncoming traffic lane if the yellow line is faded.

TesLatino with 50,000 miles on his has brought this up as a major issue. I personally have been over the line and into the rumble strip on the side of the interstate. It is bad enough that I will disengage especially while passing a semi. I also have a Model 3 with no issues in the same locations.

My goal is achieved. Local service has added checking hugging left line on FSD to its test drive check list. This is all I wanted and the manager said a high percentage with enough replies would cause him to add that action.

I could ask for videos, but there was/is no need and that might deter some votes.

I agree about the FUD, but spamming useful threads is just as damaging for those seeking information.
