I also hear all the hype about how the autonomous speed selection is better- but it’s definitely not. It might be OK if the speed limit data in navigation were correct- but it’s not. I was using FSD almost 100% of the time- I can no longer do that in good conscience- the vehicle drives dangerously, going way too fast even in sloth mode (what a stupid name btw for a mode that drives full speed limit)

‘’sloth“ is supposed to go the speed limit- it does, ‘from a certain point of view’ as Obi Wan said- but it goes what the navigation system thinks the limit is, not the posted real speed limits. Sometimes it appears the system will read a speed limit sign, but not often. Certainly not often enough.

I’ve asked Tesla to revert my CT to FSD13- they will not. They keep telling me FSD14 is better- it is not. I have taken lots of local trips, and 200+ mile trips on highways and interstates- I do not see a significant improvement in driving behavior over FSD13. On local streets I’m disengaging FSD14 dozens of times during each drive. On the highway it requires far far more driver intervention on the scroll wheel to keep anywhere close to a legal or even safe speed, and often requires disengaging. Click up, click down over and over and over to toggle between modes to attempt a safe speed. On the interstates, instead of relaxing at a set speed, one must constantly monitor the car speed creeping up into ‘moving violation‘ territory while keeping a sharp eye out for the State Troopers to avoid a speeding ticket. How is that an improvement?

And even toggling mode, the control is imprecise, with the vehicle speed oscillating going from too fast to too slow instead of a steady set speed. It’s really aggravating. A couple weeks ago my drives, whether neighborhood streets or interstates were almost stress free. I love my CT, was one of Tesla’s biggest supporters and best salesmen. That has all changed with this one removal of allowing the driver to set maximum speed. It’s really upsetting to lose a cherished part of my day. I loved my self driving Tesla a couple weeks ago, always looking forward to taking it out - not so much today. I’m looking for a workaround that does not involve trading the vehicle.

As it is now, FSD14 is dangerous, drives illegally fast and instead of increasing FSD use, it’s going to decrease it. I can no longer use FSD on 90% of my local drives because it speeds way over the limit due to incorrect speed limit data. The autonomous drive is doing what it’s supposed to do, but it’s operating on bad speed data, and the developers have taken away the ability for the driver- who is legally responsible for the vehicle- to correct the critical error of incorrect speed data. It might be doing things better behind the scenes, but in reality it goes too fast in many settings.

I don’t care that much about E2E- I can pull into my garage myself and enter and exit parking lots myself. Before FSD14 I might used FSD in a lot a few times, but I could at least have the vehicle drive at a safe slow speed. Not anymore- it tries to do 45 in most parking lots before I hit the brake.

oh, and now the car tries to stop and flashes ‘stop’ as I pull into my garage, thinking in incorrectly that there is an obstacle. Never did that before.

FSD14 has only been out a short time, but I don’t think the decision to prevent the driver from setting maximum speed is going to age well. I don’t like it all. I’m hoping for an update that corrects this decision. Maybe a option to “manually set max speed” like ManMax in addition to MadMax.

Tesla sales are hurting. My primary reason to own a Tesla is the ability for the vehicle to self drive in neighborhoods and local drives, which most manufacturers do not offer. It seems Tesla has effectively withdrawn that ability from their cars and trucks. I do not think this decision is going to help sell Teslas. I hope the devs come to their senses and it’s a temporary decision.
Yeah... Ummm... NONE of what you wrote above is happening to me, and I also live in Florida. FSD14 is working fantastic so far. The only thing it can't do is pull into my garage successfully. But considering my garage is less than a foot longer than the CT, that doesn't surprise me at all.

You have captured the fundamental problem with FSD14. I’m happy for the improvements but the elimination of the driver’s ability to correct speed limit errors makes the whole update useless. There are speed limit errors everywhere. Cutting out that one feature was a foolish and dangerous decision that I hope gets corrected soon. Worst part is that we already had a working solution to correct those errors, both too high and too low, the ability to correct was already there but the ‘update’ took it away. Even though FSD14 drives a bit better, it’s now much more frustrating, much less usable and much less safe.

I’m genuinely happy that FSD14 works for you. I want it to work for me. The only real issue I have is speed management. The rest is minor, I can even accept the phantom swerves, but I’m unhappy with having to repeatedly disengage for speeding when it was working just fine before the update. Maybe it’s location specific, but I’m having the speeding issue in SW Florida, central Florida and in the Keys. I’m not even upset about the higher speeds- I’m upset that I can no longer control the maximum speed when it does not match the posted speeds. When it’s too slow, I can control it by stepping on the accelerator. When it goes too fast the only option I know of is to disengage.

Megadittos! Model S with 14.2. I’m down with the Modes, but we need to be able to fine tune the speed, especially on the highway.

I've got news for you.

If you want FSD that will always go exactly 9 mph over, you are out of luck for the rest of your life. The technology adapts to existing conditions taking into account the weather, the traffic movements and placement around you in real time.

It's self-driving because you are no longer making the decisions. If you want to make the decisions you will need to drive it yourself.

Think of it this way: Actual autonomous driving will be many times safer than human drivers, in part because it's intelligent and doesn't base speeds and paths on personal preferences, but on what works. That means the technology actually has intelligence and it won't take kindly to backseat drivers, not anymore than you do. FSD is disrespecting backseat drivers more and more every iteration. At first it wanted all the help it could get, a little nudge of the accelerator telling it was OK to proceed, etc. But the more developed it becomes, the more it will tell you to stop trying to drive the car, it knows what it's doing.

That's why these things are being gradually removed, they are becoming more baked into the operation of the system, based on actual knowledge of risk present. If you want to drive, then drive the car yourself!
Absolutely nonsense.
The FSD Does NOT know best. In Alaska I was able to scroll down my speed in FSD to what I was comfortable with. IE. Moose, Ice, Fog etc. I have complained to know avail. I bought it becausei had controller and I MADE THE CORRECT SPEED..FSD does not! I spent money on the wrong vehicle. NEVER AGAIN. I was told not to use FSD in those instances. THEN WHY SHOULD I NOT GET REFUNDED THE 8 GRAND IT COST FOR FSD?

I am happy to say FSD 14.2 seems to have fixed most of the speed issues. Standard drives up to 5 over on the highway consistently. It is odd on suburban roads standard does the speed limit, it doesn't stick to the reasonable amount over, I would prefer it to be consistent across all types of driving. No more speeding past lines of traffic doing 20mph over in standard is a good thing though.

Good points. It is ridiculous not to be able to adjust the speed when the truck is often going the wrong speed, according to the SPEED LIMIT SIGN.
When I hear FSD is 10x safe then a human driver, they are WAY off.
I DO NOT speed through school zones, turn into on coming traffic, hit potholes like they are not there, pull out of side streets in front of traffic, change lanes from the right lane into the middle lane, 1/2 mile from my righthand exit, change lanes in front of speed vehicles, sail through red lights and stop signs, read state route signs like the speed limit (NYS 25...When the speed limit is 45 or 55) make a left turn out of my driveway AFTER I punch in a destination and the GPS is showing and knowing it need to make a right...because a LEFT is a dead end...? Almost every time also. BUT, NOT every time so that mean it does know not to make a left turn to the dead end. Left turns drive over the median almost every time and right turns sometimes are aiming for the urb to shred my tires.
CURVATURE ASSIST ACTIVE. I get that message quite often ...except it is on a STRAIGHT road, no traffic, no curve, but it insists on mashing the brakes.
I have gotten a strike, will looking straight ahead with out a warning. I only have taken my eyes off the road after the truck starts beeping like mad, since it surprises me and the noise annoys the hell out of me.
AUTO DRIVE...fails almost every time. Pulled into a spot against a building, step on the brake and it goes into drive. Other times, it should go into drive but it goes into reverse. It makes no sense at all.

Ron, I didn't say FSD always knows best, I said it's Full-Self Driving because it's the one doing the driving. You are simply supervising. If you don't like what it's doing, you have a right to take over driving duties at any point.

You should not be refunded (and if your read the terms of the sale of the FSD option you would know why it would be ridiculous in the extreme to refund your money).

FSD will never always go the speed each individual thinks is the perfect speed. Because you can please some of the people, some of the time, but you can never please all of the people, all of the time. Sometimes people wonder why FSD is slowing down, right up until they see that FSD knew more than they did. It could have been a toddler who just broke free of mother's grasp, a dog running out from behind a parked car, a car running a red light.

if you look at my posts, I’m having a very similar experience with FSD14. The vehicle I bought had a fully functional and safe FSD that allowed me to set a safe and legal maximum speed while self driving, and manually correct the myriad speed limit errors in Tesla maps. The vehicle I own no longer does that. That extremely basic safety function was taken away by The FSD developers. I would prefer to have my fully functioning FSD back. (Of course it could have been left in as an option, it’s most definitely a choice to advance autonomous driving, not a programming issue). We’ll wait and see how it goes with tickets and safety problems and who is going to ultimately be responsible for damages after the lawsuits. But for now I personally do not like losing the use of FSD in my neighborhood when I’ve had it for a year and it’s worked very well: just had to roll down to meet the 10, 15 and 25mph speed zones as the maps think the limits are 30 and 45mph. Now I just cannot use it. It’s a personal loss for me.

There's only so much FSD can do when it misreads or has bad data for traffic speed. The logic to maintain traffic speed when that happens really improved phantom braking. I do think it needs a maximum offset and straight maximum. I believe FSD is maintaining a safe speed for its awareness and reaction time, but its not the responsible party at the moment. NC will suspend your license automatically for 15 over or for > 80mph. I used to use Mad Max Navigate on Autopilot; I want the vehicle to be confident and assertive in how it drives, but I need it to control its speed.

Yeah now I am just on the gas pedal and getting the red alert it will not brake warning, then i let off. I am currently driving on this method until further notice.

Agree with eswimm 100%. That’s it in a nutshell. I preferred when I could make a separate selection for assertiveness and a different selection for maximum speed. FSD is in no way ready for full autonomous driving in part because it cannot consistently select a safe and legal speed.

I just got home from a short local drive with my wife who once again insisted that I shut off FSD for going too fast in our neighborhood. She says it’s dangerous and she will not ride with me using FSD if I can’t control the maximum speed.

Thanks, Tesla developers, for getting me to decrease my use of FSD. WAY TO GO.

I love v14.2 except for the elimination of maximum speed control. FSD thinks that my 30mph residential street is 55mph. I've been reporting the error for months. We definitely need the max speed control.
