After a month-long delay, Tesla sent FSD v12.4.2 to employees yesterday with update 2024.15.10. After just a few hours of the update going out to employees, Tesla started sending it to OG testers as well, who were already on FSD v12.4.1.
Issues Behind Delay
On X, Elon Musk broke down some of the details behind the delays. He mentioned that part of the issues behind the V12.4.2 delays were based on training. Tesla was seeing fewer interventions with FSD v12.4, but the release suffered from driving smoothness, which ironically was supposed to be one of the key features of this release.
Musk explained that part of the issue was due to too much focus on interventions, and not enough on normal driving. He compared it to training a doctor on emergency room patients, versus training on regular preventative care.
Vision-Based Attention Monitoring Changes
With FSD update 12.4.2, Tesla changed some of the language used for its Vision-Based Attention Monitoring in the release notes. Here’s a breakdown of some of the key points in the language. The changes to the release notes are below. Phrases or words that were removed are crossed out, while those added are in bold.
“When Full Self-Driving (Supervised) is enabled, the driver monitoring system now primarily relies on the cabin camera to determine driver attentiveness. This enhancement is available on vehicles equipped with a cabin camera and only when the cabin camera has clear and continuous visibility of the driver's eyes Cabin camera must have clear visibility (e.g., the camera is not occluded, eyes, arms are visible, there is sufficient cabin illumination, and the driver is looking forward at the road ahead and not wearing sunglasses, a hat with a low brimwithout sunglasses, or other objects covering thetheir eyes). Outside of theseIn other circumstances, the driver monitoring system will continue toprimarily rely on a combination of torque-based (steering wheel) and vision-based monitoring to detect driver attentiveness. When the cabin camera is actively monitoring driver attentiveness, a green dot appears next to the steering wheel icon on the touchscreen.
If the cabin camera detects inattentiveness the driver to be inattentive, a warning will appear. The warning can be dismissed by the driver immediately reverting their attention back to the road ahead. Warnings will escalate depending on the nature and frequency of detected inattentiveness, with continuous inattention leading to a Strikeout.
Cabin camera images do not leave the vehicle itself, which means the system cannot save or transmit information unless you enable data sharing.”
Arms Need to be Visible and Other Changes
There are various interesting changes here. While some of the changes are just improved wording to make the feature clearer, there are others that are worth highlighting which could point at changes to Tesla’s vision-based monitoring.
The first is the addition of “arms are visible.” Apparently, Tesla now wants to be able to see your arms to better detect attentiveness. Tesla may want to see that your arms are on the steering wheel, or they maybe they want to make sure your arms are moving so that someone isn’t able to post a static photo in front of the cabin camera to circumvent the attention monitoring. The reason isn’t clear, but looks like having your arms visible is now a requirement.
There are other small changes like the removal of a “hat with a low brim,” which was replaced by more generic wording that says the driver’s eyes must be visible.
However, near the end, Tesla removed the portion that said the driver monitoring system will rely on a combination of torque-based (steering wheel) and vision-based monitoring. This was changed to simply say that Tesla will rely primarily on torque-based (steering wheel) monitoring when vision-based monitoring is unavailable. It’s not clear whether this is just semantics and the wording now better describes how the vision-monitoring feature works, or if Tesla made changes so that the vehicle is simply either doing vision monitoring or steering wheel torque detection, and it doesn’t try to combine the two sources to detect whether the driver is paying attention.
Even more interestingly, the last line that says “cabin camera images do not leave the vehicle itself, which means the system cannot save or transmit information unless you enable data sharing,” has been removed. This could point to Tesla saving images of the cabin camera to improve its AI training model.
Either way, we’re glad to finally see FSD v12.4.2 going out to employees and early-access owners. The release is expected to have far fewer interventions and improve vehicle smoothness during braking and acceleration. If there are no major issues found, this update could go wide to all customers with FSD and on update 2024.14 or lower in the coming weeks.

Tesla has finally launched the refreshed Model Y Long Range Rear Wheel Drive (LR RWD) in the United States. While the refreshed Model Y RWD was available as a Launch-Series option in the Asia-Pacific and European markets, it wasn’t yet available at all in North America. Once the Launch Series stopped being offered, Tesla began shipping non-Launch Edition Model Y LR RWDs in Asia and Europe earlier this year, but didn’t bring it to the United States until now.
The LR RWD is one of Tesla’s most affordable vehicles, starting at $44,990 (or $37,490 after the Federal EV Rebate).
Model Y LR RWD
Spec-wise, the refreshed Model Y LR RWD is a compelling alternative to the AWD model. Tesla has kept the premium interior and audio options on the North American variant, so you get the full experience of the refreshed Model Y. You also get more range and faster charging than the AWD model. The only downside is that it’s two-wheel drive and slower acceleration. However, given the lower price and additional range, those may be worth the tradeoffs.

Availability
The Long Range RWD is expected to begin shipping immediately in the United States. Tesla has not made the vehicle available in Mexico or Canada yet, likely due to tariff complications. Once the tariff rates settle, Tesla will likely look to export the vehicles from the U.S. to the other two North American countries.
With the arrival of the Long Range RWD variant, the last version we’re waiting for is the refreshed Model Y Performance. That’s likely to be an exciting vehicle, and we’re hopeful it will be in customers’ garages before the end of 2025.
Tesla is adjusting its Supercharger prices based on current usage in a new pilot program. Tesla’s pricing structure has typically revolved around traditional time-based peak/off-peak schedules but is now migrating to a more dynamic model based on live Supercharger utilization.
This development, announced officially through the Tesla Charging X account, should make Supercharger pricing more accurately reflect the demand for the specific Supercharger site instead of basing pricing on past usage.
Live Utilization Pricing
The core of this new pilot will launch at just 10 Supercharger sites in North America. The particular sites in question have not been clarified, but one of the locations is the Supercharger located in Davis, California.
Tesla intends to expand the pilot based on feedback and the success of the initial rollout. We could be looking at the future of Supercharger pricing around the globe.
New Chart and Features
Today, Tesla typically offers two or three prices based on peak and off-peak demand, meaning that Supercharger prices are based on the hour of the day. The current Supercharger chart in the vehicle shows the hours and price on the X-axis, while the Y-axis is the typical demand (image below).
The current chart for Superchargers versus the new one at the top of the page
Not a Tesla App
However, with the new charts that will soon be added to vehicles, Tesla will display the time on the X-axis, and the Y-axis will show the historical demand and the current price (photo at the top of this page).
In theory, the Supercharger's historical demand and real-time usage should be pretty similar, but there will be exceptions, like holidays and other events. Unexpected high and low usage will play a role in the pricing, such as sporting events and natural disasters. If the Supercharger is busy, then pricing will be high; otherwise, it will be low.
This also introduces a new feature, since pricing is now based on actual demand, users could navigate to a Supercharger that is less busy and, therefore, cheaper. In the hero image, we can see that Tesla will add a new “Find Lower Price Charging” button in a future vehicle update. This will likely highlight other nearby Superchargers that are less busy and less expensive.
However, it seems like Tesla may also start charging more for Superchargers than they do today when they’re extremely busy. Judging by the screenshot Tesla shared, the estimated usage never passed the $0.45 per kWh at the Davis, CA Supercharger. However, it seems that there’s a new price of $0.54 per kWh when the Supercharger usage is at its peak.
The good news is that Tesla is being more transparent and indicating whether the price is low or high with new labels. This change will give users more choices in terms of charging prices. If you want to save a few bucks, you can drive to a less busy Supercharger. The price will also be based on actual usage, which seems like a fairer way to determine price.
While Tesla hasn’t updated vehicles yet to show these new charts, the latest version of the Tesla app already incorporates the changes.
What Tesla Says
Max de Zegher, Tesla’s Director of Charging, elaborated on the pilot program on X.
He points out that Tesla Charging’s rates have been consistent, and it has focused on improving the charging experience and availability. Off-peak and on-peak pricing will help to increase both of these.
Tesla has outlined exactly how this new live feedback loop will function. The more accurate real-time station demand can allow Tesla to adjust pricing if a station is experiencing congestion during traditionally “off-peak” hours. On the flipside, if a station is unusually empty, Tesla can reduce the pricing.
This easily incentivizes customers who are keeping an eye on charging costs, as changing your charging destination can be as simple as the tap of a button. Most interestingly, Tesla says that the average price paid by customers is expected to remain the same as with the previous time-based system, even with seasonal and real-time fluctuations.
Crucially, owners can always see the price per kWh on their vehicle’s primary display, as well as in the Tesla app before initiating a charging session. Additionally, Tesla will not change the pricing mid-charge, so there’s no need to worry about it fluctuating up or down while you’re charging.
When reading some of our old blog posts, you'll find that @TeslaCharging has been consistent in its pricing principles: improving the charging experience and Supercharger availability. True to those principles, we're now piloting live site utilization for off-peak and on-peak… https://t.co/rIqQzOZfcG
This move to live-based pricing is being presented as Tesla’s latest step towards managing its vast charging network with a more customer-centric approach. Tesla has had some historical progression in its pricing strategy, so let’s take a look at where we were versus where we are going.
kWh-Based Billing: Tesla has long pushed for billing by the kilowatt-hour (kWh) as the fairest method for customers to pay for the exact energy consumed, avoiding session fees that can obscure actual energy costs. This is now standard in most regions, but it wasn’t too long ago that pricing was determined by the minute.
Idle Fees (2017): To address vehicles remaining plugged in after charging was complete at busy sites, idle fees were implemented to improve stall availability – a practice now common across the industry.
80% SoC Limiter (2019): At busy locations, Tesla introduced an automatic 80% state-of-charge (SoC) charging limit (which users can manually override) to encourage faster turnover, as the final 20% of charging is significantly slower.
Time-Based Peak/Off-Peak Pricing (2020): Pricing based on estimated busy times was rolled out to incentivize charging during less congested periods, helping to distribute demand and manage costs.
Congestion Fees (2023): At particularly busy sites, congestion fees were introduced. These combine the principles of idle fees with disincentivizing charging to a very high state of charge when a station is crowded, with the stated goal of improving availability, not generating profit.
Commitment to Affordability
Alongside these pricing changes, Tesla has reiterated its focus on keeping Supercharging affordable for all its users. Tesla points out that, on average, in North America and Europe, Tesla’s Superchargers are 30% cheaper than other fast-charging options while also being far more reliable.
Beyond that, 2025 is set to be Tesla’s largest year for expanding the Supercharger network while also replacing many older V2 charging sites with faster, more capable V4 Supercharger stations.
