Speed and lane centering in FSD 12.5.5 ??

[smg]

On my 6h drive last night with hours-long stretches of essentially identical road conditions, I endlessly pushed the accelerator from under the desired speed to the desired speed—it must have been fifty to a hundred times. It would sometimes stay at the desired speed for maybe 5-10 seconds (if I was lucky) and then slowly reduce speed. It didn't matter if my lane was clear as far as the eye could see. Didn't matter if the road was straight for 20 miles. I tried slowly accelerating, slowly easing off the accelerator to try to coerce it into staying but it would always revert. I tried both the auto offset and manual "max" speed setting. I'm pretty sure I tried everything.

Are you saying I can do nothing to stick it definitively to a desired speed like every other cruise control system in the world? Are my accelerator inputs interpreted by the FSD computer only as suggestions?

This kind of behavior is more acceptable in prima facie city street road conditions, where you're not trying to maintain the same speed for hours on end, but on open road 75-85mph roadtrip conditions, its maddening.

I’m guessing an update will do something to address this. You might interrupt the FSD by pressing the right scroll wheel - look for a box on the screen inviting you to report why, and immediately press the microphone button next to the scroll wheel and describe the speed issue. Probably the more of this reports they get, the better, since it’s probably something people will tend not to report.

Once you said you tried the automatic speed control off, you confused me. It should stay at the speed you set.

I reported "will not maintain speed" at least 5 times but at some point that gets as old as constantly having to accelerate to your desired speed. ?

I have the same issue. With the automatic speed offset turned off, it still won't keep speed. It slows down up hills, which is funny to me since plain old Autopilot from 10 years ago doesn't have that problem
?

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?

I had the same issue clearly keeps it to the left. They are going to notice it if they are using it too. There will probably be an update soon. Otherwise it was great.

While FSD is new to you, (one of the approximately 30,000 Cybertruck owners) it's not new to the at least hundreds of thousands of Tesla drivers with FSD.

The speed control is part of the new automatic max speed setting that was introduced earlier this year. It tries to choose speeds that most people would drive the road at.

In other words, you aren't reporting anything that is new. Not really much need to even attempt to report it.

At this point, just press the accelerator and get up to the speed that you want and you can remove your foot until you come to a curve and then you'll probably have to press again.

This is an early release product, it is not complete. The automatic speed control is relatively brand new.


Tesla has been super focused in getting the car to be safe as well as get it to the HW3 and Cybertruck for the last 6 months.

Now that they have completed those tasks, they'll have a little more time to spend on the lot less important things such as speed control.

You have to learn it.
Find a straight away and push it up above the current speed. If going from 45 to 65, it should now stay at about 65 mph.

My CT holds speed after a pedal goose much better than my HW3 MS.

LISTEN TO US. WE KNOW THAT!

DUH, it's been that way for well over 6 months, you are not saying anything that hasn't been discussed in dozens of threads in different sites and brought up by Social Media for months.

It's been that way since Auto Max Speed was introduced. I've driven with it for probably over 10 times longer than you have in a Cybertruck.

OP here. I’m now at CT FSD 12.5.5.2 (2024.33.15) and I thought I should report that in freeway driving it is still hugging the left lane line, sometimes enough to go over into the rumble strips. I usually just let to do it, I can’t disengage and report it all the time. Rumble strips yes, though.

I also got my FSD last night and tried it out this morning.

Overall, it worked well.

The speed control is my only complaint.

I wish you could use the scroll wheel to adjust the speed. It was doing 11 over in a 65. I prefer to keep it 5-7 over. I keep disengaging it to slow it down.

Also, when I left early this morning, in the dark, it was 7 under the speed limit. Maybe that makes sense because that's all FSD felt comfortable with in the dark? It was a highway with 60MPH speed limit.

I'm sure they will work things out, but Tesla, how about making the right scroll wheel control the speed on FSD?

There is a little “speedometer” button on the steering yoke that does nothing as far as I can tell. Allow us to press that button during a trip and enjoy speed control with the thumbwheel. Humans can still anticipate conditions that FSD cannot. A small town “Speed Trap” areas with zero tolerance as an example.

I’m also having problems with lane change and can’t find the setint to limit it. My drive home from work the truck was all over the place I usually pick the left or middle and stay on it the entire drive I kept trying to override it with the turn signals it must have looked like I’m insane.

Same here. On the LIE (or any highway with an HOV) it constantly wants to get into the HOV lane. If there is not traffic in the other 3 lanes, I have to hit the turn signal to stop the lane change but it will keep trying until am past the allowable lane change marking.
It should stop trying after the FIRST manual lane change cancelation.
There should also be a way to change the route on the fly because quite often the truck does not choose the best way.

 

[65SoYoLO]

No one that I have found on these forums has the truck hugging the RIGHT lane. It doesn't do that all the time but quite often, it will ride ON the right side yellow/white line and even into the rumble strips.
WTH. Is anyones truck hugging the right side of a lane?
I thought it was fixed after a camera recalibrate but it is still doing it.

It also doesn’t make lane changes to follow the route for me. I’ve been traveling and ended up in Long rerouting loops. I wish they gave us auto pilot. So we could have ADAS without FSD.
