I'll also give it a try on my wife's 2023 car, since I'm starting to sound like Alan who also has an older model 3.
That’ll fix it for sure.
Personally I’m going to clean my cameras and recalibrate. Super important, works
every time.
It’s got to be something with the vehicles because the car obviously has no problem just going to the manual or hidden offset set speed, otherwise it wouldn’t be speeding for people! Clearly. If it doesn’t get to the desired speed, it has to be the car, or just the person involved.
No other explanation for the different experiences!

I feel so vindicated though. Yes!
Interesting, mine consistently stayed above the speed limit (5 - 10 mph) in limited testing (an hour or so).
This is a consistent observation when using the appropriate framework, as I have explained at length in widely panned responses (bizarrely). It’s unlikely to be a car dependent thing or anything like that. It’s just dependent on what the car decides the set speed should be relative to the user’s manual (or hidden automatic and adjustable) offset.
It’s not all that complicated. Play around with it and it will become clear.
it should be trivial to limit the car to your set speed offset over the speed limit when the car wants to go much faster.
All this discussion leading from this comment and it already does this! (Though as usual people are confusing this problem with the car not going the set speed.) Just dial down the invisible limit if you are in ASSO mode. You have to calculate your current hidden set speed on the fly (+50% the displayed limit, though there is an outstanding claim to be verified that it is a lower % in less assertive modes), then dial down the exact correct number of times (5mph decrement per precisely executed dial) to get the hidden limit to be the speed you want. Then wait a couple seconds for it to take effect; don’t overdo it otherwise you’ll be going 10mph before you know it. Simple! So easy. Perfect, intuitive implementation. Bravo, Tesla. If any doubts just switch to manual mode on the fly and you can see where you got to with your precise and relaxing dialing (the limit is preserved). It’s safe to do this because
the car is driving. Don’t forget that it will probably reset to 50% over at the next limit change.
Or you can just use manual mode with the percentage offset and take the guesswork out of it and start with a more reasonable offset.
It's strange how our experiences vary so much. Not just you but some others also say it goes over the speed limit but others say it's still under the speed limit.
It’s really not strange. Completely consistent. This can happen and I 100% believe everyone’s experiences. I can see exactly why this happens. I don’t know exactly how the car decides how fast (or slow) to go, of course. But that is not necessary, to understand what is happening.
For those for whom the car is traveling too fast, there is a solution as previously explained, though even that will probably still not work adequately for those people in cases with mis-detected or sudden changes in the speed limit. But it will take care of many issues, with some limitations as previously discussed.
