55 mph setting in a 45 mph zone

[Kamin]

I drove through the mountain area coming from North Carolina to Tennessee yesterday. There is a long stretch through the highway in North Carolina posted as 45 mph speed limit. I passed many signs all 45 mph with the truck clearly seeing the sign and showing it said 45 when the truck thought it knew better and maintained that the limit was 55. After seeing many signs ignored by the truck I captured this quick video of what it had shown for every one of those 45 signs.

We need the ability to set the max speed back as an option on the scroll wheel. I stay on chill all the time as it usually goes to 2 mph over the limit and is less likely to panic break as sloth. I did not ask for, want or in any way need an easy scroll through the driving modes. The screen is perfectly fine for changing modes and I want my max speed back on the scroll wheel.

100% agree. There are several posts where many of us (who are actually CT owners and not Tesla ‘influencers’ or ‘fanbois’) who are saying the same things. We need the ability to set max speed for safety and legal reasons. It makes it way more stressful to ‘self drive’ when you know you are risking a ticket or a safety incident because of incorrect speed. As I now frequently have to do, I had to disengage FSD multiple times last night as multiple speed limit signs show 15mph, the truck sees them but insists on going 30mph in sloth or faster in every other profile. I have been using FSD far less than before the decision was made to remove driver control of max speed. I want it back on the scroll wheel.

It’s certainly not a step forward toward autonomous driving if common sense says you can not allow the car to make bad decisions. It’s a safety problem and a legal issue, too. Tesla’s legal position is clearly and repeatedly stated as “FSD is a driver assistance system”, and is never legally driving the car. If the FSD speeds and the driver gets a speeding ticket, flies through a school zone, doesn’t respond correctly to an emergency vehicle,, or crashes based on its own inputs, Tesla says you were still “driving,” and it’s still going to be your problem.

Sloth will go the speed limit IF AND ONLY IF the vehicle is using the correct posted speed limit, which it often does not. And what if road conditions warrant going slower than the speed limit? It’s beyond irresponsible that every other profile intentionally breaks the speed limits. How’s that going to play out in NY?

I suspect that who ever made this foolish and dangerous decision doesn’t have a lot of real world driving experience In locations outside urban areas, and doesn’t really grasp that the whole country does not have a heavily programmed road system like in Austin. It’s ‘nice’ that they they have given us the ‘honor’ of being a test platform for the Robo-taxi software, but that’s not what I paid my six figures for.

I was thrilled with the FSD before and used it confidently almost 100% of the time, with simply adjusting the speed on the scroll wheel. Now I am frustrated and unhappy, disengage on virtually every drive, and use FSD much less than before. It’s certainly less relaxing to drive my CT now. I think that’s a pretty rotten way to treat a paying customer. Doesn’t do much to build brand loyalty.

and btw, you can also scroll through the speed profiles by clicking the right scroll wheel left or right, which means it’s redundant to have both the ‘scroll up/scroll down’ and the ‘click left/right on the right scroll wheel’ change speed profiles. It’s a waste of a button control. I’m fine if they keep the click left/right for changing speed profiles, but PUT THE MAX SPEED SETTING BACK ON THE SCROLL WHEEL WHERE IT WAS!

Completely agree except I would like to see a max speed (preferably %, but give us both mph & %) for each speed profile.
The way it is now I constantly have to change the profile to be comfortable with the speed.
I believe FSD without this suggested capability will NEVER be FULL Self Driving for me, unless (perhaps?) Tesla eats the speeding ticket.

Another awesome feature could be either notifying, but better yet modifying the speed profile (user selectable perhaps) to NOT exceed the speed limit in known speed trap areas. I was forewarned about speeding in Oregon and set the speed accordingly (before V14 using max speed to limit CT to actual speed limit).

One final thought- perhaps this all goes away with Actual FSD (not supervised) and all speed limits will be observed. The problem with this is of course some drivers (drivers because they will opt out of FSD to go faster) will put themselves and other vehicles, people, whatever at a significant higher risk.

So c’mon Tesla, give us a real hands off FSD experience that allows us to set our own comfort level, max speed % or mph for every speed profile. Even if Grok can handle this it will be a minor pain, plus currently when in Grok listening mode I don’t get any audio music, news, podcast …… Probably needs a “Hey Grok” or whatever you vehicle nickname is to indicate to Grok this next voice is directed to you. It is hysterical sometimes when Grok tries to respond to vehicle conversation not intended for Grok.

Agreed again. Good to know I’m not alone in being unhappy with losing driver speed control, as my ‘Tesla advisor’ told me. Interestingly, all 17 of my friends that own Teslas are really unhappy with losing driver speed control.

One thing, though: everyone who posts about this makes some suggestion to reconfigure speed control. I think it was already working near perfectly in FSD13- just put it back on the scroll wheel, and put the speed offsets - both percent and absolute- back on the screen JUST LIKE IT WAS. No new development, no new confusing controls. Just restore what we had. None of that need interfere with choosing to use the new ‘autonomous’ speed profiles if that’s what some owners want.

I 100% agree that we need the max speed setting back. There are MANY times a day it either fails to correctly see the speed limit sign or just makes up a speed. For example, my neighborhood speed limit is 25 MPH but it just guesses it is 60MPH. Going that fast in a 25 is NOT good. And after I leave my 'hood, it thinks the speed limit is 70 when it is actually 40. Again, not good.

As a protest, I have cancelled the monthly payment for my FSD subscription - even though I have the "one month free holiday special" right now.

I also routinely turn off FSD and send a feedback comment about "We need the max speed setting back! This is ridiculous!"

Disclaimer: I still have not bought a CT so the above comments are about my Model S.

Edit: I got pulled over for speeding for the first time in my life 4 days after FSD 14 came out. It was in an area where there are speed traps 2 to 4 times per week. *I* know not to speed there but FSD does not. I wish there was a way to give direct feedback to the team - instead of the "give audio feedback when turning off FSD" thing.

I have one of 4 CTs in my local friend group of 17 Teslas. There’s an X, an S and the rest are Ys. Every single owner is unhappy about loss if driver control of speed management in FSD14. We all acknowledge improvements in self driving, but every single one of us finds the automatic speed management without the ability to input a driver correction in FSD14 to be stupidly and unnecessarily asking for trouble. I do not want a speeding ticket, or a stressful drive- I want the scroll wheel max speed setting back.

I want to use my FSD almost full time - you were smarter than me by getting FSD by subscription. I foolishly paid the $8k up front believing FSD would just get better and more usable and that I would always own a Tesla. No more. I had no expectation that the brilliant developers would make my FSD less usable. I hope someone with sense steps in and fixes this. Soon.

I love all the new speed options especially the scroll wheel!

As jurisdictions, speed limits, and terrains change, a simple move of the scroll wheel is all that is required to continue with true, no stress, self driving, all while maintaining safe, space cushion driving.

Everyday I am more and more amazed.

I still think the best option would be to set the speed %or mph over in settings, and anything standard or lower does the speed limit, hurry or mad max does the %/mph set in the settings.
Then the right wheel control adjusts the actually speed limit the truck thinks it is, I.e when it misses a sign, or gets on a road that hasn’t posted the sign yet. When I pull into my neighborhood, it’s 20mph, but I’m getting off a 60 mph. It speeds back up to 60 for the first 100 feet until it passes the sign.

Bruv, you had the truck in Chill Mode.

RTFM.

This is the reason chill mode exists: to try and resolve bad GIS data with as little input from you as possible. FSD also uses surrounding traffic context to adjust errant speeds.

Bruv, you had the truck in Chill Mode.

Agreed the truck was in Chill at the time, but that doesn’t change the fact that FSD chose a 55 limit when there is clearly a 45 MPH sign visible.

Yep. Apparently sometime between September 2025 and now, those 45 MPH signs were added, but like everything else, our government has failed to update the GIS data. The truck can see the sign, but it ignores it because the GIS data is weighted higher.


GIS map data

As of September, these signs didn't exist on this road.

The conspiracy in me wonders if those 45mph signs were added by an unauthorized party who was tired of excessive speeding near their home

Either way, Tesla definitely doesn't have a perfect system to deal with these types of situations. They removed direct speed control because they want to wean us off of any input whatsoever.

Contact info for reporting errors.

p.s. my apologies for being a butthead earlier. my family sees you driving around Greeneville all the time, by the way lol.

 

[georgek43]

Newly posted signs and incorrect GIS data are all over every part of America (well maybe not in Austin, but it’s a problem in the real world). The rampant errors in the GIS data are EXACTLY why we need driver control of max speed restored.

Recognizing just those GIS errors is sufficient reasoning to restore the previous speed management system- it’s not a rationale to excuse the bad behavior of FSD and say- “Gee, it’s not Tesla’s fault”. It absolutely is Teslas fault for degrading a perfectly working speed management system and removing the simplest and safest method to correct for bad GIS data.

It’s kind of ironic that Tesla wants to wean us off any and all driver inputs, yet the new speed profiles are exactly driver inputs for speed, just less precise. For me, taking away speed control is Tesla becoming the nanny-state. The car knows a lot, but it does not know better than the driver in all circumstances.

Until FSD14 I considered my CT to be the best vehicle I’ve ever owned- and I’ve owned a lot of awesome vehicles- but I absolutely must have speed control restored to have that assessment again. If we lived in a world where the GIS was correct everywhere, the new FSD system might be just fine, but in the real America, it most definitely is not.

RESTORE DRIVER SPEED CONTROL!

This is the reason chill mode exists: to try and resolve bad GIS data with as little input from you as possible. FSD also uses surrounding traffic context to adjust errant speeds.

What the Developers are failing to see is that many many times outside of urban areas there is no surrounding traffic. So no matter the mode, the truck speeds up way beyond the speed limit when the GIS data is wrong, and occasionally right into a speed trap. Telling the officer or the judge that the GIS data is wrong is not likely to be a very good defense.

Here is a situation where max speed might be a negative. If you have a max speed set 5 miles above the speed limit and was going max speed, changing lanes might be an issue if there is a car in that lane behind couple of car lengths that is going the same speed but clear in front, FSD can’t go over the max speed and slowing down might not work to change lanes.

 

[georgek43]

The new speed profiles work pretty well on the highways. It’s the secondary roads, city and neighborhood streets that are the big problem and really need driver speed control. And having one does not preclude the other- the driver speed control was already programmed in, they do not even have to develop it- it could be selected as a ‘custom’ speed profile leaving sloth through mad max intact. Owners could select the new profile system if they’re happy with it by flipping the scroll wheel left or right, other owners could select to set max speed with the scroll wheel as it had been for years. The car could be nearly autonomous as the developers want for all drivers, but not all drivers are ok with that until the errors are out of the speed limits, and it could be more controlled for other drivers, which is what I paid for. It’s a better choice than not using FSD, or selling the vehicle.
