Tesla has introduced notable upgrades to its Automatic Emergency Braking (AEB) system in a recent FSD Beta update. Initially, FSD Beta 11.3, which only went out to Tesla employees, included a significant update to Tesla's automatic emergency braking.

However, when FSD Beta 11.3.1 was released to public testers, the release notes significantly differed from the employee version, leaving some uncertainty regarding the status of AEB enhancements.

Other features were removed from the release notes in FSD Beta 11.3.1, including Voice Drive Notes, which was clearly still available in the public beta. It's not clear whether the changes to the release notes was a mistake or if Tesla chosen to highlight changes between 11.3 and 11.3.1.

AEB Now Detects Vehicles Moving Across Tesla's Path

The company's impact report has recently confirmed that the improved AEB system was incorporated into the FSD Beta. The enhancements include detecting and responding to vehicles moving perpendicular to the Tesla. This advanced feature aims to reduce the likelihood of accidents occurring when other vehicles cross Tesla's path, such as running red lights or cutting the Tesla off.

This development represents a significant leap forward in AEB technology, as traditional systems mainly focus on detecting and reacting to objects and vehicles directly in front of the car. With the ability to detect crossing vehicles, Tesla's upgraded AEB system offers increased safety and assistance to drivers.

Release Notes

The release notes in Tesla FSD Beta update v11.3 say:

Expanded Automatic Emergency Braking (AEB) to handle vehicles that cross ego's path. This includes cases where other vehicles run their red light or turn across ego's path, stealing the right-of-way. Replay of previous collisions of this type suggests that 49% of the events would be mitigated by the new behavior. This improvement is now active in both manual driving and autopilot operation.

Safety Improvements Tested Extensively with Fleet Miles

Tesla has rigorously tested and validated these AEB advancements by utilizing millions of fleet miles in shadow mode. The Tesla Vision system, which consists of eight cameras, allows Tesla vehicles to identify and react to oncoming vehicles well beyond the range of traditional sensors. In addition, the Automatic Emergency Braking system offers a loud warning and rapid braking when a Tesla vehicle senses an impending collision, and the driver has not intervened.

These AEB enhancements demonstrate Tesla's commitment to improving road safety and minimizing accident risks. In 2021, US pedestrian and road-user fatalities reached their highest levels, with a 53% increase since 2012 and over 75% of deaths at night. Tesla's Model S, Model 3, Model X, and Model Y have all received five-star ratings from Euro NCAP, including for nighttime pedestrian crash avoidance. Furthermore, the Model 3 and Model Y have earned a "Superior" rating from IIHS for the nighttime performance of their pedestrian AEB systems.

Improved AEB System Expected to Reach All Tesla Owners

The availability of the improved AEB for all Tesla owners remains uncertain, as FSD Beta is currently separate from other updates. However, considering Tesla's history of prioritizing safety features, it is likely that the upgraded Automatic Emergency Braking system will eventually be made accessible to all users. This move would further solidify Tesla's position as a manufacturer of some of the safest vehicles available today.

Moreover, Tesla's commitment to vehicle safety and continuous software updates demonstrates its dedication to its customers. As Tesla learns more about real-world driving scenarios and collects data from its fleet, it will continue refining and enhancing its driver assistance systems. The result is a safer and more reliable driving experience for Tesla owners and other road users.

Integrating the improved AEB system into Tesla's FSD Beta may pave the way for more advanced driver assistance features. In addition, by incorporating cutting-edge technology and prioritizing safety, Tesla sets a high standard for other automakers to follow in creating vehicles that protect their occupants and other road users.

Tesla Cybertruck to Receive Charging Improvements in Upcoming Update

Former Tesla VP of Powertrain and Energy Drew Baglino previously mentioned that Cybertruck would be receiving charging improvements soon.

Wes Morrill, Tesla’s Cybertruck lead engineer, recently reposted Baglino’s comments on the charge speed update on June 16th and mentioned that it would be coming soon via OTA.

Charging Improvements

The 4680 cell has seen some difficulties in its charge curve, similar to Tesla’s other vehicles that have been deployed with the 4680. Tesla has alluded to difficulties in the manufacturing curve previously, and also with engineering improvements to the new cell standard, and eventually stopped manufacturing the Model Y with the 4680 cells.

However, this is the first time that Tesla has begun to deploy major improvements to the 4680 cell. It appears the improvements will allow up to 154 miles to be recovered in 15 minutes, which is approximately a 30% improvement to current charge rates.

We’re hoping that these improvements to the 4680 will also translate to older Model Y vehicles that have 4680 cells, which will be key to the owners of these vehicles. 4680 production is currently mainly focused on Powerwall, Megapack, and Cybertruck – with Semi not using 4680 yet.

Tesla Model 3 Long Range Now Eligible for $7.5K Tax Credit

In the US, the Model 3 Long Range has now become fully eligible for the $7,500 federal tax credit for EVs.

Federal Tax Credit

The federal tax credit is up to $7,500 USD off at the point of sale, which applies to EVs with batteries originating from the United States. The Model 3 Performance was launched with the EV tax credit, which meant that until now, it was cheaper to purchase than the Model 3 Long Range.

Interestingly, after this change, the Model 3 Long Range is only $1,000 USD more expensive than the Model 3 Rear Wheel Drive, as the RWD model is not eligible for the credit. The LFP batteries in the RWD model are from CATL in China, and thus mark it as ineligible.

At $40,000 USD, the Model 3 Long Range is now an even better deal than before – and is nearly $7,500 less (the amount of the credit), than the average new car in the United States.

Canadian EV Credits

In Canada, Tesla dropped the Model 3 RWD price by $1,000 CAD, in response to the province of  British Colombia reducing the upper limit of their EV credit MSRP range. This means that the Model 3 RWD is the only Tesla vehicle that is covered under the new BC rebate – which is one of the few provincial rebates still left standing.

Sadly, as a result of this change, and due to a weird classification gimmick, the Model Y is considered a sedan by the Government of BC and is completely ineligible for the additional rebates – but the $5,000 federal EV rebate still applies.

Tesla vehicles accounted for 80% of federal EV rebate applications in Canada in 2023, marking a net increase since last year at 60%.
