I suspect that with default settings, you can't. It chooses the max speed for you.
With true FSD you aren't driving, you don't get to make those choices.
If it goes too slow, it goes too slow. It is goes too fast, then it's going too fast.
When it's driving, it's driving.

When it decides that it doesn't want to drive, and it probably will, you have to know what to do.
On other Teslas you certainly can set the max speed for FSD. If it’s a divided highway it goes up to 85 mph. Non-divided is limited to speed limit +5 mph.

Around here at least it's possible to set the speed on non-divided roads to much higher (like from 30 to 60). Valuable since FSD/Autopilot often gets the speed limit wrong (most likely due to the Google maps). On the free Autopilot app you can usually only increase the speed by 5 mph.

AFAIK, it doesn't use Google maps or any other for such info. I've watched the left hand side of the screen where it shows what it recognized (in a rented base Model 3), and it clearly recognizes the speeds on speed limit signs.

The maps are from Google (look at the right side of the screen on the bottom). It does use speed limit signs but recognized "speed limits" often change where there is no sign at all. Another issue is that certain county road signs that are a multiple of 5 can trigger a speed limit change. I've heard that Tesla may be working on their own maps derived from driving data.

I just dropped off my truck to Tesla for the recalls and they let me drive a 2022 Model Y with FSD 12.5.1.5.

The speed offset is completely broken on this version of fsd. It's doing like 10 mph below the speed limit even though I have it set at +15. I changed it to auto speed and it seemed better.

It made 2 mistakes on the way back from Tesla including making the wrong turn into a parking lot lol. I had to disengage and continue straight. It also still isn't very good at lane decisions.

I don't think we want this 12.5 on the Cybertruck yet.

Not quite.

What Tesla does is admittedly a little weird.
The maps that you see on the screen are indeed Google maps.
But the maps that the vehicles use are OpenStreet.org maps. Speed Limits and such come from OpenStreets.

Well... FSD by the end of September isn't looking very likely either. ?‍♂

You are thinking about AP with the +5 mph.

FSD has never had this restriction since I started testing in October of 2021.

Partially true. Tesla gets most signs from the fleet now. They still use the OpenStreet info and Google maps as a base, but the fleet reports signs, road hazards, road conditions, traffic, etc and presents it to your car at the beginning of a drive and then resends information periodically about every 2 min according to Greentheonly.

When I was on a trip we took our Model X. I was trying to set the Cruise Control at 90 mph and it wouldn't let me. I could set it when I was going 89 mph.

Haven't tried it on the CT yet.

85 is the max for vision based AP/FSD on the entire fleet.

That means cars without radar can only do 85 with the drivers assist functions.

With radar 90 mph is the max, but they stopped enabling and, in most cases, installing radar in 2022. The S/X have radar, but it's disabled.

The auto speed setting on 12.5 is the best option but it will do 10 miles over the limit on regular streets sometimes. Maybe fsd needs to detect cops haha

12.5 has balls though way more then my 12.4.3 car. it does a way better job of following the lead car. It did try and pull out when a fast car was coming so I hit the brake.

I don’t know how the car reads the maps but I wish there was a way for it to know when a lane was ending. It will pass into a lane that is ending.

Also, Near my house there’s an intersection and on the other side the lane on the left ends. I always stay in the right lane but fsd chooses left and has to merge at the last minute.

It also has to read signs. There’s a weird situation where there’s 2 lanes but they have a sign that says turn only in the right lane. But the lane doesn’t actually end. Instead the car will stay in the turn only lane and piss off people turning lol

FSD only currently reads Speed Limit, Stop Signs, and potentially Yield signs.

The e2e has learned some "no turn right on red', but for the most part ignores School Speed limits, right on red, turn only lanes, etc.

It's still very much a Level 2 ADAS system and will make mistakes. The driver is responsible for correcting them.
