I just hope we don't have a crash like we did in mountain view where we lost Walter Huang to a median barrier.

Different circumstances but often I see guardrails and a lot of those other hard things when my truck drifts.

Surely Tesla can do better, but when?

I no, some people haven't experienced it. Sitting at 30,000 in miles plus.I experience it often.

The median-barrier incident is a good example of a critical failure mode, but that was 7+ years ago and FSD has changed significantly since then.

On a recent drive, the highway had "intermittent shoulders" where the left lane was mostly bounded by a concrete barrier, but periodically included a shoulder area for disabled vehicles to pull over. FSD would "hug the left" as per usual, but only crossed into the rumble strips when there was room to do so. It never got close enough to the concrete for me to intervene.

I think FSD prioritizes "obstacle avoidance" over "lane discipline". For instance, on city streets, it will happily cross the yellow centerline to go around a double-parked vehicle.

My guess: the NN training data is based on Tesla's cars that all have the cameras significantly lower than the Cybertruck. The differing angle throws off the estimation of distance/position.
It's for this reason that I think the early FSD versions for Cybertruck were bumping stanchions and clipping curbs on turns. It saw the obstacle, but falsely estimated its own position in space slightly. This improved with each revision and I've not seen this behavior in a long time.

Alternately, it could be SbW? I fail to understand why autopark often goes back-and-forth multiple times when I could back straight in on the first try. It's not like the parked cars are moving...?
Yeah, my guess is steer by wire but it has to be more than that. Your point about camera locations is a good one.

I would hope so. Yet it only takes one story lately.

It has come along nicely, yet no real improvement in the lane issue or speed control in recent times for active users. Other models of Tesla have the speed, but not the lane issue.

I still use FSD 95%+. Maybe it’s me being forgiving, but the hugging has stopped. It still will screw up a left turn when no other cars are Around (turning into traffic in wrong lane or in a left turn turning into the other turning lane). It will do a U-turn where no turn is aloud- that was exciting! It will speed ALL the time and has become my alter ego driver (I’ve never once had a speeding ticket).

All that to say…it is exceptional as is today. Yeah Y, S etc are better and more confident. But FSD in the CT -for me- is amazing still.

On 13.2.9
Two days ago I would have answered that I don’t have any real new issues. Yes, still hugging too far left in the left lane, too far right on city streets. Some times too narrow right turns and left turns. Did a few long trips four times 100 miles, mostly freeway, including stop/go traffic, some local streets, all OK.

Then on Sunday it suddenly behaved very strange, dangerous. Twice it just moved right, not drifting, real move, as if it wanted to leave the road, but there was no hard nor soft shoulder, just side berm. Also in slow moving traffic it slowed down to a stop and didn’t move again. I had to disengage several times, and then stopped using it.

My passenger, owner of an MY and FSD user, blamed it on shadows. Claimed he had some of these issues earlier also. The ride was through areas with trees, and the sun was very bright. Could shadows impact FSD that much? For the locals: SanJose to Santa Cruz over 17, back over 1 and 152. FSD behaved very well through the “road work” areas, but unusable to often.

I'm not sure what happened, but the cybertruck is downright dangerous on the freeway when using FSD. It drifts far outside of the lane on every turn, it crosses multiple lanes of traffic on a turn, and just cannot keep a lane. In town, it actually drives ok. I've recalibrated the cameras but no help there. It used to work ok, but now it's completely unusable. Am I the only one that notices this? If everyone else is able to use it with success then perhaps I need to take my truck in for some underlying issue.

My M3 FSD works like a champ and I absolutely love it. I wish I could use the CT with the same level of confidence. There was a time when the CT's FSD was pretty good so I know it's possible.

My CT is an earlier truck (VIN 700's) and I've owned for 18 months. I absolutely love this truck and I almost hope it's just something wrong with mine so they can maybe fix it (as opposed to the usual answer which is we must continue waiting).

I have the same issue. Unusable on the highway. Great in town.

My FSD worked ok, went in for service and is now unusable. Free for a year but to much work to use it. Hoping for an update ??

I went through the same thing on the previous release. Got super aggressive, even in chill mode and the steering wheel was doing this really weird twitch back and forth like the control loop for it was out of tune. Also was suddenly no longer able to keep its lane.
Seems better after this most recent SW update, but haven't been on the highway yet.

Mine drifts dangerous into the lanes (or shoulder) to my left when there is no traffic. I need to submit a service ticket, but honestly want to recreate it again so that I can bug report the moments when it happens, and do a few at that. With that said, I enjoy driving my truck and generally I don’t use FSD all that often.

I use FSD 13.2.9 every day and drive about 100 miles daily. I haven’t had any real issues, other than it missing a couple of exits when traffic didn’t let it merge in time. But that about it

I have to report that phantom braking is back. I have had many serious incidents of this recently, and it very much is related to patches of new pavement on the highways. I drive a 100 miles straight stretch regularly, and the car decelerates 75 to 10 mph at the same places on the highway each time.

The TACC (Cruise Control) is just as bad. I get strikes for driving around these road blemishes, and even got two strikes for pulling off the shoulder of the road at 5 mph.

Not too impressed with these logic circuits. Usually things are ok, and then -WAM - something really bizarre.

Mine rides the left line a lot. Goes over rumble strips during bends in road And rides over lines into bike lanes. Also makes left turns into oncoming traffic. But. Never when there are cars there only when the lane is empty. I calibrated the cameras on several diff highways and it has not helped. I noticed on a leaning road it falls to the down hill side of the lane. I went both directions on the same road and it fell to the down hill lane line and road that line. And even on flat roads. It can’t keep centered. Very annoying. I read people saying that having the wheels aligned helps. But that sounds like grasping for something. If that was the case why would it ride to the left going one way and to the right going the other way on the same road? If any one has a real solution please post it. I don’t know if the SC could or would do anything about this. From all the posts it sounds like it’s all software bugs. And we will have to wait for a new update. But what do I know. I did change a setting from chill to Hurry in FSD. And it seems to be driving a little better. But that’s preliminary. Time will tell.

My 23 X is doing FSD like a champ. It’s not sniffing that white line like a cocaine addict anymore. The truck is still a little too close at times for my comfort but I’m definitely not needing to take over as often.
