I have a 2024 all-wheel-drive cyber truck with full self driving. It’s has v14.2.2.2. It has consistently not recognize speed signs. That includes going 40 and a 55 or going 40 in a 35 and then a 25. Obviously, I intervene but this is a consistent problem and it can be a very dangerous safety issue. . I reported it to Tesla, but I don’t think they really give a damn. I wish they had a different way to report things rather than in the car microphone. Am I the only one having this problem? By the way, I drive the car in standard mode as well.

There’s so many posts about this it’s really not worth discussing again. But no, you’re not the only one having that problem.




[/QUOTGee, what a blow-off. Not sorry I asked, only sorry for reading a rude post.

Wasn’t meant to be rude, but people have been kicking the dead horse on this topic. I used the handy search function in the top right corner and searched “speed limit signs.” Here are the threads from page 1. There’s lots more pages but, spoiler alert, there’s no solution. Just gotta accept FSD for what it is for now.

recent update, V14.2.2.2 definitely a couple steps back for my CT and wife model Y on freeway. lots of lane change hesitation, missed an exit due to last minute fail to merge in, few moments of steering twitches, tailgating front drivers while both lane on the sides are open, and lots of signals flashes to change lane but cancelled which confused drivers behind me. Regardless, I still love TSD and using it all the time just have to be more vigilant on the freeway. can't wait for the next update.

Yes, you got to keep an eye on the speed. I have to go from sloth, to chill and on highways I use standard mode.

Are speed limit signs on the tablet screen displaying correctly?

No, you are not the only one, and the issue is much bigger than just missing speed limit signs. We had an easy way to deal with incorrect speed management by FSD with the scroll wheel, but it was taken away to promote a very premature forced paradigm shift to full autonomy, which just isn’t fully baked yet. One day it might be but until that day comes, and maybe even then, drivers need to be able to easily control the speed of their vehicles in a vast number of situations that include innumerable errors in speed limits and the complexity of overall situational awareness that the current AI simply cannot adjust to.

if Tesla set the speed limits on all roads, had perfect speed limit data, and all vehicles on the road were operating on true FSD, would driving be safer? Maybe, but Tesla does not set the actual speed limits, speed limit data is fraught with errors, and on a good day maybe 1 in 700 drivers is using FSD. FSD users are early adopters and a tiny fraction of a percent of drivers on the road.

We’re just an echo chamber here but if enough owners complain, although I am not optimistic, we just might get back The very simple and obvious way to deal with unsafe, annoying, illegal and inappropriate speeds. Imprecise speed profiles are definitely not the answer in far too many situations.

FSD14 is amazing in so many ways, but its speed management is terrible. Do not be discouraged by the fanboys, influencers, automotive writers and nay sayers who tell you to just ‘live with it because it’s the way of the future’. Nonsense. Don’t be swayed by the attempted tyranny of this minority. Call Tesla, Call the Tesla stores, Report it in the truck and report it on your app. You paid for an FSD driver assist system that usable; you deserve to be heard and acknowledged and get what you paid for.

I want to be able to safely use my FSD system on every trip, and not be just a data collector to get Tesla to the now ‘ten billion miles of FSD training’ that is the current estimate to get to full autonomy. (That number was seven billion miles, until that was reached without achieving the goal)

I love my truck and I love FSD and I want Tesla to be successful for many years to come. I also want to use FSD on every trip now, not some time in the future. Making speed management so imprecise from a driver’s perspective isn’t a good way to ensure success. Speed management is difficult for an AI and always will be, but we already had an easy way to adjust speed for errors and to assist the AI with situational awareness. The wise thing is for Tesla to restore that driver control on their own before some regulator steps in and forces something on Tesla owners that nobody wants.

FSD gets it's speed information primarily from map data with embedded speed data for each section of road that has a different speed limit. I believe most of this information is primarily sourced from state and local government public works departments (and not all are very good at it). I'm fortunate where I live and drive that the data is relatively accurate, with only rare mismatches between map data and actual signage.

I think as long as FSD is still "FSD Supervised" this is not currently a Tesla priority. As it becomes FSD Unsupervised they will need to do one of two things:

1) Pour big resources into validating the map data with the reality on the ground, or

2) Dedicate more FSD bandwidth into reading signs. This could require that Tesla update the hardware to version 5, if the bandwidth of hardware 4 is already stretched thin just driving safely.

It would be relatively easy for Tesla to make existing hardware read signs, but it could come at the expense of actual FSD safety. Tesla prioritizes safety for obvious reasons.

Thanks, I doubt Maine is going to spend the resources to update database. I live on a major E-W major road traveling from Portland through NH to Vermont.

Have noticed multiple occurrences of taking the truck speed limit as THE speed limit. Will Endeavor to report this more often.

I have a couple of places where the computer interprets the Rt 90 sign as 90MPH. Or maybe it's in the speed limit database that way. Who knows? I've cancelled FSD and sent in multiple notes about it over the past few years (I also own a Model S) but mostly have just given that up.

I suspect Tesla uses as their metric the frequency of disengagements and changes in aggregated ratio of FSD use vs non FSD use per driver to determine if features like this are working.

Lack of direct speed control on FSD is definitely a safety issue: if you want to go slower than the speed limit (for example, if the roads are icy and unfit for the limit, like they often are here in Edmonton), none of the speed profiles will accommodate - disengagement is necessary.

And speed limit sign recognition keeps getting worse.

This issue, plus frequent navigation errors (nope, I don't want to unnecessarily loop around parking lots instead of using the street, and I don't live at my neighbor's), are the only reasons I disengage.

No, it is like the camera doesn’t see it. It is a real safety issue.
I see the speed signs on the display but FSD doesnt recognize the change. Lost happened yesterday, actual speed limit 55 but CT thought it was 40 for about 20+ miles. Very frustrating driving in the thumb of Michigan.
