How FSD behaves w/ Max Speed -- explained by Tesla software engineer

explains how FSD handles max speed.

cybertruck has no chill, standard or hurry concept so this is not applicable to anything other then the S, Y, X, 3

What bugs me is when you hit 85 mph and auto steer disables for the rest of the drive. The speed limit was 85.

The problem with this thought process (user input is always an error) is that FSD does not yet get the speed right all the time on its own. Its rather offensive and arrogant to imply the driver doesn't know best when it comes to speed.

Here in Texas FSD is frequently reading the speed signs on the frontage roads (roads along side highways) and slowing down to 45mph in the middle of the highway. Its annoying and dangerous.

Not to mention, what if its my preference to reduce my trip time by 10%, why will it not respect my speed settings? This guy is gas lighting us, or they have just made a poor choice when it comes to system design/user interface.

The problem with this thought process is believing that a new product is going to be perfect before it really is released.

If the driver wants to go their speed, don't let the vehicle drive.

If you want to go faster than the vehicle does, press the accelerator!

 

[Woodrick]

Agreed. I turn off FSD super frequently for this. It's terribly annoying. Just go the speed I set. I wonder if the FSD team has done any case studies in aircraft automation. I personally don't actually want "full" self driving, all the time. I want high automation where I still ultimately have control more often than full self driving. I wonder if many others are in the same boat.

Instead of turning FSD off, just press the accelerator.

That's basically a Texas problem. (and a few other states) 85 mph speed limits don't exist for the majority of US roads.

I'd really like to have good old Traffic Aware Cruise Control... sometimes.

Dumb question...

What are voice notes?

I have screamed, "you stupid fucking thing go faster!!" augmented by my clear shifting in a toddler temper tantrum disapproval in the seat.

I like to give both aural and visual clues.

Am I doing it right?

If you're going too slow on FSD.. just press the accelerator, the vehicle speed will increase accordingly.... it's not hard

No way, I can’t stand all the phantom braking nor the loss of FSD’s 360 degree protection.

FSD sometimes makes good choices but then forgets. I drove on a 200 mile trip yesterday. I set it to the speed limit and it kept it on most straight runs. The smart thing it does is when I get to tight curves, it slows down to a comfortable speed as to not create G forces. I like that. However when it returns to the straight away, it seems to forget what speed I had set it at and it just stays slower. I then have to push the accelerator to get it back up to the speed limit. That is annoying.

I should clarify. I want to be able to use FSD but NOT have to have a destination plugged in nor have it change lanes and stuff. I want to steer but sometimes, sitting in traffic, I just want to be able to let the car keep distance.

Is he saying there's an option to select driving style? Choosing aggressive will make it go faster?

Can't you just turn off "automatic Set Speed Offset" and adjust your Speed Limit parameters to Absolute? .... seems like a pretty easy adjustment to make....

I agree. I am often turning FSD on and off repeatedly because I don't want to put in a destination but want the lane centering. If I don't turn it off at several intersections I commonly go though it trys to turn instead of going straight.

I also turned off the auto speed because it was just all over the place. Anywhere from 10 under to 10 over with no consistency or regard for traffic.

It only sets the MAX speed allowed. Basically FSD cannot drive faster than this speed. It doesn't change how slow it can go.

When you disengage the FSD a message pops up asking why did you stop FSD and if you hit the mic icon on the yolk you can talk and leave a voice message stating why you disengage FSD.

A common note they'll hear from me is that the truck hugs the line in the left side on two way traffic roads...

Once time it attempted to pass a slow driver after the car behind me past us both and then it just stopped acceleration once it moved into the on coming lane, i took over to complete the maneuver and i also hit the mic to leave a note about what just happened. Hope that helps.
