Speed and lane centering in FSD 12.5.5 ??

[Travis64]

Yes! I thought 71 in a 60 was too much. Here are some screenshots with and without.

No more speeding tickets just blame tesla

The lane position issue doesn’t seem to be the cameras. The FSD display clearly shows the truck riding the lane lines, so it is aware of the off-center position. Or am I wrong?

Yeah, that's hugging the left for sure. I wouldn't mind that when passing someone but then, it should get back into the center of the lane. I was behind someone at a light in a turn left lane and when the light changed, the person in front initiated a U-turn which is common around here and legal. My truck started into the intersection correctly but as soon as the other car began the actual turn, mine ignored it and almost clipped the car's left rear bumper. Whew... Cheat a little away from traffic, why don't ya!

Anyone listening to NPR is leaning left

I so love threads like this.

For every "the vehicle is not in the middle" thread, there's another "the vehicle is staying in the middle thread and should be further away from the other vehicles"
And I'm not joking, they can't make everybody happy all the time.

I can't tell in the first pictures, but the last picture suggests to me that it is "performing as expected" since the upcoming vehicle is near its line, the Tesla will normally move away from it.
You can see this behavior when passing 18 wheelers. The vehicle will slightly move away from large trucks. Once the pass is complete, the car normally recenters.

But the big question is, is it actively doing anything dangerous? It appears to me not to be.

Items like this change often between releases. And some have been attributed to issues with cameras.

And from my experience with ASSO (which has been around longer than 6 months) is that when on, it often travels faster on slow roads and slower on fast roads.
The faster on slow roads has been just right for me. I've got so many 25 or 35 mph two-lane roads that if the vehicle is doing those speeds, ends up with a half-dozen+ impatient drivers behind it.

I had that experience as well. It wanted to mostly do 10+ over on city streets and do 5 under on highway. Although, I had a couple of experiences where it wanted to do 10+ over on the highway. Due to that I turned it off for now.

Same. For local backroads ASSO is better. If I set manually to 70mph it only does 20-25mph, whereas it will do 30-35 on ASSO. Problem is, it reads speed limits terribly, so once I get on the main 45mph road, ASSO thinks the speed limit is 35 and won't go over 40, even with cars passing all around. It would be nice if there was a way to quickly toggle ASSO with a long push on the scroll wheel or something.

The issues I’ve seen so far is it wants to follow a little to close in city traffic, wants to accelerate aggressively only to have to apply the breaks aggressively a few hundred feet later and uses active breaking a lot more than I would instead of relaying on single pedal driving style. If it were my teen driving I’d probably have a few words on technique?. It does handle a busy street remarkably well merging from one lane to another in tight traffic. Overall amazing!

GM John. I agree with everything you said. To me this build seems to follow too closely in stop-n-go traffic and seems NOT to be relying on regen braking as much to slow down. FSD needs to learn one pedal driving a little better. I think FSD needs to be more predictive in braking in traffic conditions. Still love my CT and nice to finally have FSD.

Use the accelerator pedal to speed it up

That gets old. Might as well drive myself.. which is usually what happens.

Then do so.

But a periodic accelerator push is far less work than controlling the steering.

Yes if it was occasional. Steering is easy. Relaxing. I just want cruise that works. TACC came crippled. Now it’s better. Other than doing 25 in a 35 or 45 in a 65 when max is set over speed limit. It’s easier and less frustrating to cancel until past the problem area and then resume where it works fine. Which btw is traffic. Life saver. I can finally look around and ignore all the crazies. It handles being cut off 1000x better now. I’ll take the wins, and expand where I use it as it improves. But I’m not going to fight it for miles tapping the accelerator 100 times hoping this time it will maintain speed.

Mine was hugging the left lane line yesterday and drove in the rumble strips for about half a mile till I corrected it.

After driving nearly well over 50,000 miles with various versions of FSD. I can tell you that moving to the Cybertruck became a strenuous exercise. Steering is only easy to you because you are used to the stress of it. I've now become aware of just how stressful it is.
Think of it. What are you continuously, nominally subconsciously, doing when driving? You are watching the roads, the distances to the lines.
It's like being in a noisy environment all day. You get used to it, you don't think that it is bothering you. But then you go outside, into the country where it is quiet and you realize that strain that your body was going through.

I now had to keep an even wider vehicle between the lines! And I pretty well kept my foot on/near the accelerator with TACC as much as I had with FSD.

It's been so nice for the last few days, the truck driving me to lunch with no interventions, just maybe periodic accelerator presses. Hands and arms now sit on the arm rests.

The FSD learns that behavior from the data given to it, I.e. it learns bad behaviors from other drivers. It will also go way out when passing around trucks, some prefer that, but I hate it. It’s one reason I preferred TACC in my model S vs FSD, it would “lock” the vehicle in the center of the lane, I loved it.
