Tesla’s 400-mile Model S is a subtle update, but it’s a chilling reminder to rival carmakers
There is a particularly interesting trend happening in the electric vehicle sector. While it is undeniable that Tesla is leading the industry’s shift to EVs, veteran carmakers are prone to claim that they have or are developing technology that is at par or superior to the electric car maker’s innovations. The Tesla Model S’ 402-mile EPA rating subtly sends a message that this is not necessarily the case.
For some time now, there has been a lot of talk surrounding Tesla and its upcoming Battery Day event. The company has been pretty thin on the specifics of the event, but speculations are abounding that discussions will be held surrounding the company’s next-generation batteries. Tesla has not formally hinted at the details of these batteries, though all signs point to cells that would be able to last a million miles. Discussions about other innovations such as cobalt-free cells for China-made Model 3s are also expected to be held at the event.
Similar to how vehicles like the Porsche Taycan and the Audi e-tron were dubbed as “Tesla Killers” in previous years, veteran automakers such as GM appear to be keen on establishing the idea that it is not being left behind in the EV race. Just last month, for example, GM Executive Vice President Doug Parks stated that the automaker’s own “million-mile” battery is “almost there.” Parks stated that there are multiple teams within GM that are working on zero cobalt batteries as well.
Such statements from GM only validate Tesla’s points about electric vehicles. The fact that the veteran automaker’s battery plans seem to be inspired, at least in some way, by the younger EV maker means that the auto industry has now reached a point where electric powered transportation is a given. That being said, there is very little doubt that the Model S’ updated EPA ratings, which show that the 100 kWh flagship sedan could go 402 miles on a single charge, is likely sending some chills down the spine of Tesla’s rivals.
As noted by Tesla CEO Elon Musk, every Model S that has been produced since January has been equipped with a 402 mile range. This feat, as stated by the company in an announcement on its official website, was accomplished through a variety of means, including significant mass reduction, new aero wheels that optimize efficiency, increased drive unit efficiencies, and optimized regenerative braking.
What this means is that Tesla was able to draw out 400 miles of EPA range from a 100 kWh battery pack using its current battery technology. The 400-mile Model S today is just a hyper-optimized version of the Raven series that came out last year. Unless Tesla states otherwise on Battery Day, it appears that the current generation Raven Model S is not yet equipped with the company’s next-generation million-mile batteries.
It should be noted that other companies have pledged to release vehicles with a range of 400 miles as well. Electric pickup maker Rivian’s flagship R1T pickup truck goes 400 miles too, but that vehicle is equipped with a 180 kWh battery pack. The GMC Hummer EV, widely speculated to be a legitimate competitor to the Tesla Cybertruck, is also poised to be released with a 400-mile range. But just like the Rivian R1T, there’s a good chance that its battery pack will be substantially bigger than the 100 kWh pack used in Tesla’s flagship sedan.
Of course, it would be easy to argue that larger vehicles like the Rivian R1T and the GMC Hummer EV would obviously need more batteries due to their size, but it should be noted that Tesla’s Cybertruck, which will likely have a battery that’s far larger than the Model S’ 100 kWh pack, has some impressive range as well. During its unveiling, Elon Musk noted that the all-electric pickup’s tri-motor variant will have over 500 miles of range. The specifics of the Cybertruck’s battery have not been disclosed by Tesla yet, though it is almost certain that it will be utilizing the company’s million mile battery cells.
So what does this mean for the Model S? With a million-mile battery and a 100 kWh pack, the flagship sedan’s succeeding generations will most likely achieve a range estimate that’s even more impressive than its current 402-mile EPA rating. And this, ultimately, is something that will be very hard to meet or compete with, especially among veteran automakers that have not dedicated the same amount of time and effort into developing battery technology from the ground up.

Tesla briefly offered one Robotaxi part in its Parts Catalog for your personal car, only to remove it just a short time after it was first noticed.
Tesla’s Robotaxi camera washer apparatus was briefly available for purchase on the company’s Online Parts Catalog. The camera washer was first noticed on Model Y Robotaxi vehicles about six months ago in Austin.
🚨 Tesla looks to have installed Camera Washers on the side repeater cameras on Robotaxis in Austin
pic.twitter.com/xemRtDtlRR— TESLARATI (@Teslarati) January 23, 2026
First noticed by Not a Tesla App, the Camera Washer entries appeared for the new “Juniper” Model Y under a category called “Halo,” which has also now disappeared. Interestingly, Halo probably is related to Tesla’s internal “Project Halo,” which was a project that aimed to retrofit customer-owned Model Ys into functional Robotaxis.
This hardware addition would likely be required for the vehicle to operate as a Robotaxi, as the Camera Washer seems to be a non-negotiable part of the vision-based system Tesla utilizes for self-driving efforts.
However, this part has since been removed and is no longer visible on the EPC.
Now the true question lingers: Why would Tesla add this Camera Washer to the Model Y parts catalog? Is it planning to make it available for owners to utilize on their own cars for personal use, or will it become a prerequisite for Robotaxi operation in customer-owned cars?
While discussing the upgrade options for Hardware 3 vehicles during the Q1 Earnings Call, Tesla CEO Elon Musk had said that the company could establish small, satellite shops that would upgrade cameras and self-driving computers. Perhaps this same strategy could be utilized for vehicles that want to be included in Robotaxi but do not have the correct hardware.
AI4 is currently represented as capable of unsupervised self-driving, and the same was said about HW3 at one point, only for Tesla to admit last quarter that it would, unfortunately, not be possible. Perhaps AI4 vehicles might need this camera washer as a prerequisite, just as HW3 cars will need that camera and computer upgrade.
This could be the first hint of that’s where we are headed.
Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.
Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.
But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:
Tesla has finally turned off the blinker/turn signal noises in their Model Y Robotaxis.
This is a small update, but will definitely be noticeable for riders. It didn’t really make much sense to leave the turn signal sound on when it’s Unsupervised. pic.twitter.com/ITwx60PAMO

However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.
Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.
I kind of like it being on, threw me off when riding with Zoox who has had it disabled

Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.
The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.
Tesla released Full Self-Driving version 14.3.6 last week, and after what was potentially one of the best FSD releases in v14.3.5, there has been a bit of a regression. While there are some bright spots, the changes made to v14.3.6 seem to have backtracked some behaviors.
Overall, it is hard to really complain about FSD in any sense; it has revolutionized how I travel literally anywhere. According to my self-driving app, the last time I went a day without using it was 59 days ago.
However, I think it’s also important to recognize when things are just plain bad with FSD. There are times it does truly mind-boggling things, and I’ll dive into those here. Additionally, I only had these issues on local roads, not on highways. Highway operation, generally, is always incredible other than the occasional complaint about speed or left lane camping.
With those things being said, my personal experience may not represent others’ experiences. A handful of people have said they have had a similar experience on v14.3.6, while others have said it is more than normal.
Turning Hesitancy, Inaccuracy
I’ve noticed more inaccuracy turning into multi-lane stretches of road than in any version I can remember. I’ve had at least three instances of FSD turning into a stretch of roadway that has two or more lanes, and not selecting a lane confidently as it has in past versions.
I think Tesla FSD v14.3.6 is a regression from previous .3 branches
This version in particular has been incredibly hesitant, jerky, and indecisive at times. There’s actually been two drives that I have decided to not used FSD for the remainder of the trip. These were local trips… pic.twitter.com/YobHDOKRS6

Instead, the car will drive over one of the dashed road lines, and the steering wheel will jerk back and forth before picking the lane. It should be said that it has always picked the correct lane when choosing based on the navigation, but it is still very indecisive. The steering wheel jerking is reminiscent of some of the later versions of v13.
I admit I really hate to see the steering wheel jerking come back. However, I think when Tesla releases v14.3.7, it won’t be present. When there are occurrences of it in FSD versions, it is usually resolved by the following release.
FSD Disregards Manual Turn Signals
This is my biggest bone to pick with FSD other than Navigation issues, but this one seems like it would be such an easy fix.
If Tesla is going to put the word “Supervised” on the end of “Full Self-Driving,” then when I tell the car to do something, it should do it. If I input an increase in speed by pressing the accelerator, the car will immediately respond. It does not disregard my input because it feels it is traveling at the right speed.
FSD should never disobey and turn off turn signals that the driver inputs. Trying to direct the car into the correct lane, I had initiated the left turn signal not once, not twice, but three times, with the car turning it off all three times and continuing in a lane that would end in just one block. The only solution at this point would be to zipper merge.
This goes back to the fact that self-driving’s biggest bottleneck might be rider preference. A zipper merge might have been more than reasonable, might have saved me time that I spent sitting through an additional light cycle, and might be something many drivers would do. I was in no hurry, I traditionally do not try to zipper merge because it feels inconsiderate, and lastly, the car should have just followed my input.
This caused me to disengage and drive manually the rest of the way home. Sometimes I just do not need FSD to try to pass every car it can at intersections.
Bird Braking is a Thing of the Past
The big complaint with recent versions of Full Self-Driving has been what we’ve coined as “bird braking,” which is when the car will brake suddenly as a bird flies past.
There have been zero issues with this so far in v14.3.6, which is an excellent improvement.
FSD Might Already Be Taking Note of Driver Preferences
Another thing I have noticed over the past few days is that v14.3.6 seems to already be taking my preferences with navigation into account.
This is something that is supposed to be rolling out with the Summer Update, but I have a hunch it’s already present and might have been included in this v14.3.6 build. On Friday, FSD pulled into an entrance to a local convenience store that it had never attempted to go into before.
Typically, I manually pull into this entrance because it avoids heavy cross traffic at the main entrance. FSD has always chosen that congested main entrance.
I don’t want to get anyone excited but my Tesla running FSD v14.3.6 just:
✅ Pulled into an entrance at my local Sheetz that I routinely pull into manually but FSD never has entered
✅ Pulled into my assigned parking space at home despite many other spots being vacant https://t.co/ZUShvknTWO pic.twitter.com/83O5a2S0eh
— TESLARATI (@Teslarati) July 24, 2026
Additionally, FSD has pulled into my assigned parking spot at my townhouse community on multiple occasions with this release. This is something that used to happen ocassionally, but not consistently.
It also navigated back to the same convenience store last night, drove through crazy cars scrambling to gas pumps, navigated out of the parking lot correctly, drove me home, and, once again, parked in my assigned spot.
As previously stated, this release just seems to have a few things that need to be brought to Tesla’s attention, and also to make others who use FSD aware of some things that I’ve experienced. I look forward to the next release that will remedy these issues, just as Tesla has always done in the past.
