2026.20.6.11 Update now downloading.

Two very noticeable changes with this release:

1) Speed under "standard" setting is much less aggressive. It'll only go about three miles over posted speed limit and with an accelerator nudge it'll speed up and hold, but only for about 15 seconds before settling back into three miles above.

Not my experience. I did over 100 miles on FSD today and I tried STANDARD and the speed was only 15 mph but there were vehicles in front of me. It would have gone over that, most likely the usual 20 over if there was no one in front of me.

2) The truck wants to be in the right lane much more than before. It has gone so far into the right lane, it is getting caught up in merging traffic congestion vs. driving around it in the far left lane. Sadly, for me, this is causing far more interventions because I don't want to sit in congestion when there is a clear path around it.

Again, not my experience. In CHILL mode, instead of the usual 2mph over, it kept to the 55 mph speed limit but then it slowed to 53 mph temporarily, it would jump into the left lane and do 55mph. That is ridiculous.
The choice between the speed limit, 2 mph over the speed limit, and TWENTY mph over the speed limit is completely unacceptable and probably illegal.
They need to fix it.
I have noticed from many posts on the forum that different trucks with the same software react differently. I do not understand how that is possible.

One of the first different reactions I noticed was that the majority of trucks would hug the left side of a lane. My truck would hug the right side of lanes.

Sorry if this has been discussed, but has anyone with the new Base AWD ($59k) version received any software updates?
I am currently on 2026.14.200 and FSD 14.2.2.5

For decades, the dominant method for setting many speed limits in the United States has been the “85th percentile rule,” which by design expects that a portion of drivers (about 15%) will regularly exceed the posted limit under free-flow conditions.

As for enforcement, police can legally ticket anyone going over the speed limit by an amount that exceeds the error of their speed measuring device but they tend to not do that, only enforcing speeding when it becomes objectionable (in most cases). And "objectionable is a fuzzy line, different in different jurisdictions and different for different officers.

If FSD always adhered rigidly to every speed limit, even those set unreasonably low, other drivers would become frustrated which would naturally lead to more accidents, not less. FSD will not drive faster than it judges is safe, but it will also not adhere rigidly to every speed limit (sometimes it will drive below the speed limit if it thinks the speed limit is too high for conditions). The bottom line is that FSD attempts to drive much like a reasonable person would. Studies show that changing the speed limit on a section of road has a limited effect on the actual speed people actually drive and FSD behaves very much like this. Is it strictly legal to exceed the speed limit by a small amount? Of course not. Is it reasonable? In many cases, I think so.

This is why Tesla gives us speed profiles, so each individual can balance their risk of getting cited for a speeding ticket vs. frustrating other drivers, in a manner that suits their personal risk profile.

This is a exceptionally accurate analysis of speed limits, and how an autonomous system should behave within them. Posted speed limits are rarely adhered to by drivers, and driving strictly the speed limit can be not only frustrating to other drivers, it can be downright dangerous (e.g. driving on a 65 mph interstate in a pack of vehicles all going 80 mph).

Once all or most vehicles are autonomous, they can adjust speeds to match conditions and just run at the fastest safe speed. Until then, FSD has to somehow strike a balance between safety, convenience, complaisance and risk of citation.

So, you’re on the factory software. Which is always the case when you get a new Tesla. The time that it takes for you to get an update depends on when the next release that they consider “stable” comes out after you took delivery.

It could be hours, days, or months. i’ve personally experienced all of those. There’s no accounting for it. All you can do is hurry up and wait.

It’s not you, it’s me - I need some stability in FSD, I think we should take a break and explore the current version. We are just moving too quick, let’s just slow down and enjoy what we have.

Also just got it this morning, and installed it. Noticable that installation would take just 30 minutes instead of the usual 50. Of course in practice it was even less. Must have been a very small but critical “fix” that they pushed so quickly.

Maybe a security flaw needed patching before exploitation. Or after.
