Tesla Full Self-Driving’s biggest improvements from v13 to v14
Tesla Full Self-Driving (Supervised) v14 has been out for several weeks now, and there are a tremendous number of improvements, as we have now reached the fourth iteration of the semi-autonomous software.
Tesla began the v14.1.4 launch last night, which included minor improvements and addressed brake-stabbing issues many owners have reported. In my personal experience, the stabbing has been awful on v14.1.3, and is a major concern.
However, many things have improved, and only a couple of minor issues have been recurring. Many of the issues v13 addressed are no longer an issue, so Tesla has made significant progress.
Here are some of the most notable improvements Tesla made with v14 from v13:
Better Lane Switching on Highways
One of my biggest complaints with v13 was that the “Hurry” Speed Profile would often stay in the left lane, even when there were no passing cars. The legality of cruising in the left lane fluctuates by jurisdiction, but my personal preference is to drive in the right lane and pass on the left.
That said, Tesla has improved FSD’s performance with more courteous lane behavior. It no longer camps in the left lane and routinely gets back in the right lane after passing slower cars.
More Awareness for Merging Traffic and Makes Courteous Moves
There have been times when FSD has been more aware of merging traffic, and even cross traffic, than most human beings.
Here are a few examples –
- Full Self-Driving lets a car out of cross traffic during a busy time of day. This road tends to get very congested, especially during rush hour, so the car that was let in by FSD would have been sitting there for likely a minute longer if my Tesla had not let him in:

- A busy, four-lane expressway with a quick exit on the far side of the highway for this merging vehicle. I’ve seen some drivers be extremely inattentive and travel at the same speed as merging cars, making their entry onto the expressway less seamless. FSD doesn’t do that; it makes way for merging cars:

More Confident Driving Around Mail Trucks…and Amish
I encounter a lot of Amish in my area of Pennsylvania, and they commonly use both shoulders and the road, so traffic can get congested at times.
In the past, I’ve taken over when encountering Amish buggies, mail trucks, or other vehicles that are moving slowly or making frequent stops. I have felt it is more logical to just take over in these situations.
I decided not to yesterday on a long drive through Lancaster, PA, and the FSD did a wonderful job of confidently overtaking these vehicles:

This was really impressive and fun to see. There was a slight stutter during one of the three instances, but overall, I didn’t have any concerns.
Object Avoidance
On v13, I almost let the car drive into a fallen branch in the middle of the road. A mile later, the car swerved out of the way for horse droppings. It was a beautiful, clear morning, and the fact that the car did not try to avoid the branch, but did steer away from poop, was concerning.
Tesla has obviously done a great job at refining FSD’s ability to navigate around these road hazards. Last night, it swerved around a dead animal carcass in the middle of the highway. I didn’t see it until we were already going around it:

It was awesome to see this and never feel alarmed by the sharp movement. The maneuver was smooth and really well done.
Better Speed Consistency
With v13, I felt I had to constantly adjust the Speed Profile, as well as the Max Speed setting, when using FSD. With V14, I don’t feel like I am making as many adjustments.
Tesla axed the Max Speed setting altogether with v14, which was a good move, in my opinion. Choosing the Speed Profile is now more intuitive by using the right scroll wheel. If the car is traveling too fast or too slow, just change the profile.
Three things Tesla needs to improve with Full Self-Driving v14 release
V13 had some issues with local roads, and I felt it would travel at strange speeds. In a 45 MPH zone, it would sometimes take a long time to reach 40 MPH, then hover between 43 MPH and 47 MPH. It would then fluctuate between those two speeds, frustrating drivers behind me, understandably.
V14 gets up to speed much better and travels at speeds I’m much more comfortable with on both local roads and highways.
For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.
It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.
Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.
The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.
Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.
The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.
SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.
There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.
The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.
Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.
The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.
On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.
Tesla Cybercab has one important piece that AI4 cars might need for FSD
It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:
“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.
It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something
There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.
Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.
Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.
Here are the full release notes for the suite:
- Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
- Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
- Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
- Introduced parking, unparking, and reversing capabilities.
- Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
- Speed Profiles are now available at all times, to further customize driving style preference.
These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.

He added:
“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.
