Tesla Cybertruck Lead Engineer Wes Morrill recently shared some insights on the electric vehicle maker’s deep integration and unique approach to car design in a recent post on social media platform X. As could be seen in the engineer’s post, it is Tesla’s intense attention to detail that ultimately makes the company’s vehicles as disruptive as they are today. 

Anyone informed who looks at the Tesla Cybertruck would know that the vehicle is a symphony of automotive engineering. Tesla, however, took some time before it reached this point. As per Morrill in his post, Tesla in its early days utilized different teams with collaborative goals in vehicle design. Adopting this system allowed the company to make great cars, but the designs of the vehicles themselves were not optimal. 

“A well known example – early days of Tesla there was a battery team and separately a vehicle structures team. Structures team designed their vehicle body to meet given requirements of strength, crashworthiness, torsional stiffness, etc. Likewise, the battery team designed their part to be self contained, it could survive durability, accidentally being dropped, being hit in a crash, etc.

“As a result, we ended up with was a super dense battery in a strong box like structure, which was then Installed into the vehicle which had a nice space for it to mate into. There were no issues with integration, everything fit together perfectly and met all product goals. It achieved one of the highest crash safety ratings measured at the time.

“But we had a box full of battery cells that was installed into another empty box shaped receptacle on the body. A box in a box. When you simplify it down that far it sounds obviously wrong. The two organizations had achieved their goals, worked together without friction, and the product met its overall goals. Yet the product ended up with a clear lack of optimization as a result of the organizational boundaries of the two teams working in isolation. Nothing was wrong, but it wasn’t optimal,” Morrill wrote. 

The Cybertruck Lead Engineer noted that Tesla learned from these experiences, and the company adapted. This is how innovations such as the structural battery pack—which is now being simulated by electric car makers in China—came about. Morrill stated, however, that such changes may require large organizational changes, and there has to be a drive to make the best product regardless of ego. 

“Before the next product was designed, the battery team gave responsibility of the battery structures also to the vehicle structures team. On this iteration, we ended up with the structural battery, which is an integral part of the body and crash structure. Without it, the vehicle body will not work. It’s the literal floor for the vehicle. But the redundancy is gone and the design is more efficient as a result. This vehicle also achieved one of the highest crash safety ratings measured at the time.

“This is a super obvious example (in retrospect) and solved with a fairly large organizational change but you can also see this happen in small technical decisions and doesn’t require structural change to fix. Someone just needs to question if there is a better solution in a team open to criticism. This mindset to work together to make the best product regardless of ego is where you end up with the most innovative products.

“Some smaller examples have been seen when inspecting Cybertruck design. The chassis air suspension which is used to pressurize the battery pack to prevent water ingress. The subwoofer which utilizes the air volume of the body side instead of making the enclosure larger. Centralized zonal vehicle controllers instead of many small distributed controllers. Doors which use the exterior surface as a crash intrusion beam. The pedestrian warning system used as a horn. The list goes on. The excitement and motivation by everyone involved to work across boundaries and actively break down Conway’s Law is one of the many reasons I love working at Tesla,” Morrill wrote.

Supply Partners Group has secured a distribution agreement for the Tesla Powerwall in Australia, with inventory expected to arrive in late February and official sales beginning in mid-March 2026.

Under the new agreement, Supply Partners will distribute Tesla Powerwall units and related accessories across its national footprint, as noted in an ecogeneration report. The company said the addition strengthens its position as a distributor focused on premium, established brands.

“We are proud to officially welcome Tesla Powerwall into the Supply Partners portfolio,” Lliam Ricketts, Co-Founder and Director of Innovation at Supply Partners Group, stated.

“Tesla sets a high bar, and we’ve worked hard to earn the opportunity to represent a brand that customers actively ask for. This partnership reflects the strength of our logistics, technical services and customer experience, and it’s a win for installers who want premium options they can trust.”

Supply Partners noted that initial Tesla Powerwall stock will be warehoused locally before full commercial rollout in March. The distributor stated that the timing aligns with renewed growth momentum for the Powerwall, supported by competitive installer pricing, consumer rebates, and continued product and software updates.

“Powerwall is already a category-defining product, and what’s ahead makes it even more compelling,” Ricketts stated. “As pricing sharpens and capability expands, we see a clear runway for installers to confidently spec Powerwall for premium residential installs, backed by Supply Partners’ national distribution footprint and service model.”

Supply Partners noted that a joint go-to-market launch is planned, including Tesla-led training for its sales and technical teams to support installers during the home battery system’s domestic rollout.

Tesla Giga Berlin growth could stall if not “free from external influences”: Elon Musk

The comments were delivered in a pre-recorded video discussion.

Tesla CEO Elon Musk has reportedly warned that future expansion of Gigafactory Berlin could be jeopardized if the site does not remain “free from external influences.”

Musk’s comments were delivered in a pre-recorded video discussion with employees and came at a sensitive moment for the facility, where union representation has been a recurring issue.

According to reports from Handelsblatt and Der Spiegel, citing participants at the event, Musk suggested that if Giga Berlin is no longer “free from external influences,” further expansion would become unlikely. He did not, however, hint that the plant would shut down.

While Musk did not name IG Metall directly, his remarks were widely interpreted as referencing the union, which is currently the largest faction on the works council but does not hold a majority, as noted in an electrive report.

The video conversation was conducted between Musk in Austin and Grünheide plant manager André Thierig, then played back to the workforce in Germany. Works council elections are scheduled for early March, heightening the tension between management and organized labor.

The CEO has previously voiced concerns that stronger union influence could limit Tesla’s operational flexibility and long-term strategy in Germany.

Despite the warning on expansion, Musk praised the Giga Berlin site during the same address, describing it as one of the most advanced factories worldwide and highlighting its cleanliness and team culture.

The discussion also reportedly touched on battery cell production. According to attendees cited in German media, Musk indicated that Tesla has begun ramping cell production at the site. That would mark a notable shift from earlier expectations that large-scale cell manufacturing in Brandenburg would not begin until 2027.

Tesla Full Self-Driving’s newest behavior is the perfect answer to aggressive cars

Tesla Full Self-Driving appears to have a new behavior that is the perfect answer to aggressive drivers.

According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.

With FSD’s constantly-changing Speed Profiles, it seems as if this solution could help eliminate the need to tinker with driving modes from the person in the driver’s seat. This tends to be one of my biggest complaints from FSD at times.

A video posted on X shows a Tesla on Full Self-Driving pulling over to the shoulder on windy, wet roads after another car seemed to be following it quite aggressively. The car looks to have automatically sensed that the vehicle behind it was in a bit of a hurry, so FSD determined that pulling over and letting it by was the best idea:

We can see from the clip that there was no human intervention to pull over to the side, as the driver’s hands are stationary and never interfere with the turn signal stalk.

This can be used to override some of the decisions FSD makes, and is a great way to get things back on track if the semi-autonomous functionality tries to do something that is either unneeded or not included in the routing on the in-car Nav.

FSD tends to move over for faster traffic on the interstate when there are multiple lanes. On two-lane highways, it will pass slower cars using the left lane. When faster traffic is behind a Tesla on FSD, the vehicle will move back over to the right lane, the correct behavior in a scenario like this.

Perhaps one of my biggest complaints at times with Full Self-Driving, especially from version to version, is how much tinkering Tesla does with Speed Profiles. One minute, they’re suitable for driving on local roads, the next, they’re either too fast or too slow.

When they are too slow, most of us just shift up into a faster setting, but at times, even that’s not enough, see below:

There are times when it feels like it would be suitable for the car to just pull over and let the vehicle that is traveling behind pass. This, at least up until this point, it appears, was something that required human intervention.

Now, it looks like Tesla is trying to get FSD to a point where it just knows that it should probably get out of the way.
