How can I make my Y go 78 mph?

Turn off FSD and put your foot on the accelerator.

This is why I prefer to use autosteer (autopilot) on the highway.

It worked fine before the mode thing. Just set a speed and car would drive. Annoying if you needed to accelerate, but it worked. My best guess would be set speed limit to 78 and hurry. Then if it wants to slow down a bit, hit accelerator and should keep it near the goal. I’ve taken the lazy approach and just quit caring. A few MPH even over a couple of hours of driving just isn’t worth sweating for me now. More audiobooks I guess.

Under safety and security (I think it's in parental controls) you can set a max speed limit of 78mph. The only caveat is that it also applies when not on FSD as well. Plus you can't change it while driving. It will do what you want but it's not the best way to do it.

Autosteer will allow that setting.

Then why have FSD?

No idea why they took away the max speed setting. Yes the modes come close, but not quite close enough especially considering we are not really just passengers right now (we do have to pay attention). I have to think that adding it back would for SURE increase FSD usage. I use FSD a lot (more than 60% of all my driving) with my 2024 Y. But I had to drive my sons 2020 Model 3 that just has autopilot for 3 highway hours yesterday and I have to admit being able to set a specific max speed again was great. (although the fact that you have to disengage autopilot to make lane changes and you have to hold the wheel was not really worth it) The only thing I would say is you have to quit thinking of FSD as cruise control, it's not, it's driving, you are just riding. Set it to chill mode and enjoy the ride. The speed offset you are talking about is just for the speeding warning indication. It has nothing to do with FSD behaviour. FSD ignores it and you can only kind of control it's speeds with the Modes (Sloth, Chill, Standard, Hurry, and Mad Max)

Does autopilot still give the incessant “touch the wheel” nags?

Because it drives the car for you even if it doesn’t do exactly what you might do.

Not all engineers are smart, some just passed the test. Yeah they fucked FSD with the speed profiles and the indecisiveness when changing lanes. I do not understand, with respect to the car choosing to drive itself over the speed limit, would that not open Tesla up to litigation if the car was speeding in FSD and it killed the occupants of the Tesla or 3rd parties involved in a wreck? They just got hit with $230mil settlement for one of their cars running a stop sign and killing someone. It would be simple for them. Allow the machine to drive the speed limit, and anything over that is a physical button click by the driver. If I want to relax on my 450 mile commutes, I need to know the speed I am doing at all times. I cannot relax with FSD driving. FSD should be renamed to 'New York City Cab Driver Mode'.

It hasn't changed in years...so yes especially when its dark, or you're wearing sunglasses. It works okay, but there are incidents of phantom braking, phantom emergency vehicles, and curvature assist on straight sections of road. On the plus side it's not horrible on highways and doesn't cost $100/month. It also allows you to set the max speed either directly or by a percentage of the speed limit.

The lack of control over the speed is one of the things that killed FSD for me during the free trials. Because I wasn’t allowed to set to speed, FSD tried to get me to go 77mph in a 45mph construction zone — and in front of a cop, too.  FSD has exceedingly poor situational awareness for o chiming AI. The good news is that, when you turn off FSD in the settings menu while you have a subscription, you get Enhanced Autopilot (EAP) as a fallback — which is a really good driver’s aid, and should be the default driver assistance software on all Teslas in 2026. *P.S. The other thing that FSD did to scare me was to advance toward high-speed cross-traffic (>55mph) at a rural Midwestern T-intersection with unobstructed visibility for 1/4 mile in every direction.  Definitely a code-brown moment.  Between those two events, I won’t even use even FSD for free.  But EAP is really good, and I’d love to see it bundled with the $120/year connectivity package. I’ve had my Tesla for 3.5 years and I’m actively shopping for my next 3-row EV, and Tesla’s competitors generally have ADAS capabilities that fall in between those of Autosteer and EAP — so Tesla could make all of their cars more competitive with a simple firmware update.*

Kind of pointless if you have to supervise it more than a regular cruise control.

You don’t have to supervise it more, just the opposite since you don’t have to steer. You just have to accept that it might not drive at the same exact speed that you would.

You mentioned Chill then Hurry. What about Standard?

Screw Autopilot. Dealing with all the nagging reminders is far more stressful than actual driving.

Set it to standard mode, as it’s between hurry and chill? Honestly in FSD I think Tesla is trying to get you to accept that you are being driven, not doing the driving. So you don’t get to say that it goes 78 mph. I’m generally fine with this. Where I’m not fine is that the car doesn’t detect or adjust to speed limit changes properly, so it can be going along at 72 in a 65, and all of a sudden, the speed limit drops to 45 in a work zone and it keeps plowing along at 72. Or, it camps in the left lane going slower than the cars behind it. These issues need to be fixed.

I guess I'm alone in liking how the different settings perform. I use them all in different scenarios and once I got use them I like them how they are.

I do like the steering part but I find I spend more time and stress supervising the speed and lane changes. The speed is the big one. The worst scenario so far was one day at 3am in a 55mph in dense fog I caught it doing 77mph. It wasn't even a divided highway. Autosteer is simple. Set it and forget it. Lane changes are a PITA. But as far as alerts from the car go, I rest my hand on the bottom of the wheel and don't get any 'apply pressure' messages.

What’s wrong with 75?

If you drive for three hours straight at 78mph you go the same distance as if you drive for three hours and seven minutes at 75mph. It’s safer and more efficient to go 75mph. Just go 75.

You are not alone.

Assuming standard also is not working for you, use the mode that goes slightly over the speed you want > Disengage > then reengage FSD when driving at the speed you want it to go and it tends to drive the speed it was rengaged at for a while until conditions change. The only time i find this does not work is if trying to engage FSD to stay under the speed limit. The reason Tesla removed it likely has to do with how neural net and AI training work. It was likely hindering FSD in a few ways to try to get it to force hold a speed. V14 has shown how much better it got overall without that constraint. No humans drive a consistent speed either and I’ve hated how all cruise controls on other cars speed up way too much for the conditions. I personally welcomed the change to profiles. The up/down scrolling never worked right in v13 and was annoyingly slow to adjust.

Are you HW3 or HW4?

While I fully understand and agree with the desire to go a specific speed and lock it in, the correct option here is to just drive 75 mph. The difference over even 2 hours of driving is less than 5 minutes of extra travel time. While that’s not ideal and we should have more fine control over the car we’re supervising and ultimately responsible for, it’s really not that big of a deal. Just set it to go 75 mph. But also, why not try Standard? You mention Chill and Hurry, wouldn’t Standard make sense to try?

Just a data point - on my drive to work today, speed limit is 65. Standard mode in v14.2.2.5 kept me at a steady 72mph. I have the offset set at 5mph. The only thing I'm still not crazy about is the following distance it chooses. It's a bit too close for my comfort level even though I realize that as a computer, its reaction time is much better than mine and would be able to slam on the brakes much more quickly than I could. Still...makes me a little nervous following that closely.

The speed limit thing is worthless now. The modes override it in fsd unless you disable fsd for dumb cruise control

Get a nag eliminator and use autopilot

Isn’t the offset only for the speed limit indicator?

I would love it if they allowed like, basic autopilot (MAYBE at most an equivalent to the old Navigate on Autopilot) on a single pull of the stalk, and keep FSD on a double pull. Like things used to be to differentiate TACC from AP.

Put larger tires on the car. The speedometer will be off and 75 on the speedo would be closer to 78mph actual.

Good question. I honestly have no f'n clue what the offset does. I just set it for 5mph in case it has something to do with how many miles over the speed limit it will go. But it doesn't seem to make a difference so I have no idea.

It worked fine before the mode thing. Just set a speed and car would drive. Annoying if you needed to accelerate, but it worked. My best guess would be set speed limit to 78 and hurry. Then if it wants to slow down a bit, hit accelerator and should keep it near the goal. I’ve taken the lazy approach and just quit caring. A few MPH even over a couple of hours of driving just isn’t worth sweating for me now. For FSD, I just scroll max speed down to 78, or whatever target speed and set mode to hurry. It works for me most of the time.

You can’t. And yes, it sucks

I need those 7 minutes!! /s I never understood that. I'll go 7-8 over, keep up with traffic, whatever. But it's always crazy to see people stressing, weaving in and out of lanes, all to save just a few minutes.

Yes

It is truly absurd to accept the way the car drives. Why? Because they give us modes. If thy can give modes then they can allow for more choice.

Interestingly it works perfectly in free Autopilot. I set a number and it holds there until it has to slow down.

Until the car can be ticketed for speeding and not me, you should be able to tell it a maximum speed offset honestly.

Well I will spoil it. It’s in regards to the speed limit indicator. The speed limit sign in screen gets marginally larger when speeding

Air resistance is proportional to the square of speed. So while 7-8 mph doesn’t seem much it takes a lot more energy to do so. If you are driving longer distances, driving faster will just cause more frequent and longer SC stops practically erasing the benefits of driving faster.

lol.....that's it??? It has nothing to do with the car keeping a speed relative to the speed limit? It just sets a speed above which the speed limit icon gets bigger??? That's hilarious if that's really all it does.

Ya that’s what it does. Thats why it’s under the section it is (I forget what’s it’s called)

It's in the Autopilot (now renamed to Self-Driving) menu.

TACC or the pedal manually

I just want a method to set for 10% over any speed limit

7 minutes in a 3 hour continuous drive.

That’s too much!

Ya but the section in that page I mean

Try this. Select Autopilot. Set Speed Limit Warning to display or chime. Set Speed Limit to Absolute. Then you can set Limit to whatever you want your maximum speed to be. Your car will not go faster unless you press the go pedal.

Set it to standard?

lol, wrong. Have you ever taken a long trip in EV? Put your number into ABRP and see how wrong you are.

So physics isn’t real?

Traffic moves at about 78 on I4, 528, and I95 in FL. So 78 is probably safer than 75 under those conditions. I would also argue that telling someone to just go speed the car is willing to go is a non-answer. Likely this issue translates to roads with other speeds. What if the speed limit was 65 instead of 70 and I wanted to go 68,but the car would only go 65 or 70? I just want basic FUNCTIONALITY that has existed since cruise control was invented.

Standard went 75, Hurry went 82. Regardless of offset setting. If I went to standard then hit the accelerator until 78 it would slow back down to 75 after releasing the pedal. If I was doing 78 and clicked up to Hurry, it would creep back up to 82. The lack of control is becoming enough for me to drop my FSD subscription.

Blocking other cars because EVERYONE else is doing 78, for one. For #2, I would say something like, "I ought to be able to have my car go the speed I WANT, not that the car wants". Which is why cars have an accelerator pedal rather than a rotary switch.

My bad, it was a typo... I was in standard and hurry mode. I need something in-between. Something with less than a 7 mph delta in speeds.

Lol, I can respect this answer more than all those that say "just do what the car wants to do". I'm not a minion and the day I have to defer to my car is the day I dump it and go back to my 370Z. :-) Likely, I will wind up unsubscribing to FSD if the concept is truly about "letting it drive me the way it wants to", rather than my (possibly misguided) expectation that it is supposed to be a tool to simplify and help me drive the way I drive (you know, like cruise control, lane assist, blind spot detect, auto-headlights, auto wipers do on my other cars).

Sounds like a you problem honestly. 75 is over the limit and you can be ticketed. Sure you’re not. But you *can* be. Get in the left lane and don’t block “EVERYONE”

My thoughts in no specific order are: 1. It’s a developing technology 2. We should voice our opinions about the technology and hope they’re listening to improve it 3. People need to chill a bit and not get upset when the car goes 76 instead of 78 when it’s in self-driving mode. Relax.  4. If you don’t like it, don’t use it 🤷‍♂️

For me, partial capability is not worth $100/mo. In my situation, having control over highway speed on congested Florida highways is almost as important as having the car navigate. This was my first 400 mile trip with FSD. I will try Autopilot next time and see if it gets me closer to my expectations set by my other cars, and save $100/mo until they offer a capability I will be happy with.

Yup, if it doesn’t work for you, simply don't use it.

Lol, my wife's car has that and I do the same thing, keeping my hand at about 7 o'clock position so that the weight of my arm is enough to keep the system happy. I've been tempted to try attaching a velcro wrist weight at about 9 o'clock to see if I can drive hands free and still have the system happy. It's just easier to have my hand on my thigh rather than hanging on the wheel on a long trip (and yes, I'm ALWAYS watching the road - too many tourists driving in FL not to) And actually, I'm thinking I would prefer initiating lane changes rather than letting FSD do it. On the trip mentioned, on 3 occasions FSD tried to switch left to the next lane within 3/4 of a mile of my exit - and in two of those cases, the exit required 2 lanes shifts to the right from the lane I was in. So had I not intervened, FSD would have done worse than a Canadian tourist trying to get to Disney World shooting over 3 lanes in about 1/2 mile. 😱

It was a type: standard and hurry were the modes used, 75 or 82 mph, nothing in-between, which is what traffic was doing

Actually, adaptive cruise control (like on my other cars), does exactly what I want. Set to 78 and the car never exceeds that speed, if the traffic slows down from that, the car slows down to follow. My wife's Infinity lets me set the gap distance as well. And it auto stops and go's when in a traffic jam without me needing to touch the brake or gas pedal.

Ya, cause in the end it's more about the reaction time of the guy behind you.

I think literally everything in that reply is wrong. Left lane on I4 or I95 at 75 mph will DEFINITELY block EVERYONE. 75 is within the margin of error and guaranteed you either won't get ticketed on a FL highway, or a judge will dismiss the case My post has never been about tickets or speed limits. It's about letting a driver have control over their car and being able to drive at a speed they are comfortable with. Not faster than they want so they are at risk, and not slower than they want which in SOME SITUATIONS (like traffic on I4), has been proven to increase risk due to forcing other drivers to route around a slower vehicle. I guess wanting to drive 78 mph in a car that refuses to let me do that could be a "me problem". I guess I'm just not that big of a minion to be content with that. More power to you if you are willing to let your car decide for you. Some people may be fine with a car that has no accelerator pedal too - that would be a "me problem" too.

Oh shit...I think if we had a face to face conversation we'd be laughing too much....you got some personality I can tell! Also Florida here, Pensacola. As far as weights are concerned...I've done some of the research for you. I have a velcro wrist brace and it seems the perfect weight is a 500ml bottle of water with a single sip taken out of it. I brace it to the 3 o'clock position (not the 9, because when you forget to remove it all hell breaks loose in turns with it hitting the indicator stalk). Over my 450 mile commutes, after about 300 miles it decides to tell me there's a defeat mechanism and I need to remove it. So I take it off, disengage the autosteer, re attach the water bottle then good to go. I usually get the alert in fairly quick succession; around the 300 mile mark. My first weight attempts were a peanut butter sandwich and 2 boiled eggs hanging off the 9 o'clock position. Yep, you read that right. And it's only because they fucked up the FSD.

Idk, I use it every day, usually on hurry or standard

I mean they all still have TACC which is what you are describing. It does not steer the car though.
