Tesla CEO Elon Musk has provided some context behind the electric vehicle maker’s rollout strategy for FSD 12.5, a highly-anticipated update to the company’s advanced driver-assist system. As per Musk, FSD 12.5’s initial rollout is currently focused on Model Y units equipped with Hardware 4.0 (HW4).
Tesla FSD 12.5 has started rolling out to its first wave of users, though observations from longtime testers have hinted that Tesla seems to be releasing FSD 12.5 only to vehicles equipped with HW4 for now. One of these testers was longtime FSD user @WholeMarsBlog, who noted that HW3 vehicles do not seem to be receiving FSD 12.5 yet.
In a response to the FSD tester’s post, Elon Musk explained that Tesla is indeed focusing on Model Y units with HW4 for FSD 12.5’s initial release. Once the initial rollout is successful, Musk noted that the release of FSD 12.5 will broaden. He also noted that Teslas with Hardware 3.0 (HW3) will run the same parameter count as vehicles with HW4, though doing so requires extra work to optimize the code.
We are focusing on just Model Y with HW4 for the initial release. Make sure that works well, then broaden.
This has the 5X increase in parameters.

end-to-end on the highway is coming in follow-up 12.5.x releases. So is driver monitoring support for sun glasses.— Ashok Elluswamy (@aelluswamy) July 23, 2024
FSD 12.5 has so far been receiving positive reactions from longtime testers of the advanced driver-assist system, though users have noted that the update seemed to lack some previously teased features, such as the merger of city and highway software stacks and vision monitoring support for drivers wearing sunglasses.
There was a huge focus on improving both safety AND smoothness in this release. One of my personal tests is to not spill an open cup of coffee while on FSD. 12.5 was the first version where I was able to do that for 30 min long drives. https://t.co/C65OSCetjY— Ashok Elluswamy (@aelluswamy) July 23, 2024
As per Tesla Autopilot Director Ashok Elluswamy, these features should be released for FSD 12.5.x releases. He also noted that Tesla focused on safety and smoothness with FSD 12.5. “End-to-end on the highway is coming in follow-up 12.5.x releases. So is driver monitoring support for sunglasses,” the Tesla executive wrote.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.

This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade
Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.
Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.
Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.
Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error.
More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report.
Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.
Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.
Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.
“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
