한 여성이 테슬라를 구입했는데, 불과 15일 만에 심각한 사고로 차가 완전히 파손되었습니다. 다행히 그녀는 가벼운 찰과상과 타박상만 입고 무사히 빠져나왔다.

@yeoulabba It's a beautiful car. Congratulations to your wife and hope she enjoys the car and the FSD. Oh, and to you too.

명의(名義) 테슬라 모델S Plaid Ultra RED. 나는 차를 선물한 게 아니다. 명의를 선물했다. 결제는 내 삼성카드 전액 일시불로 했다. 캐시백 1.2퍼센트, 놓칠 수 없었다. 그러나 등록증에 찍힌 이름은 아내 것이다. 삼십 년 가까이 내 곁에서 버텨준 사람에게, 소유권이라는 단어를 선물하고 싶었다. 생각해보면 우리는 늘 거꾸로 산다. 비싼 물건을 사면서 정작 이름은 자기 것으로 남긴다. 사랑한다면서 소유는 양보하지 않는다. 이상하지 않은가. 진짜 주고 싶다면 이름까지 줘야 하는 것 아닌가. 아내가 웃었다. 그 웃음이 1020 마력보다 강력했다. 제로백 2.1초보다 빠르게 내 마음을 흔들었다. 빨간 차는 원래 눈에 띈다. 그런데 그 차 옆에 서 있을 아내가 더 눈에 띄었다. 레드가 어울리는 여자와 결혼한 건, 돌이켜보면 내 인생 최고의 투자였다. 수익률 따위는 계산할 수 없다. 계산되지 않는 것들이 진짜 값진 법이다. 캐시백은 내가 챙겼다. 명의는 아내가 가졌다. 이 정도면 공정한 거래 아닌가.

@ray4tesla 3 mph. Watch your speedometer on the screen. Currently, FSD does not move until the displayed speed goes to zero before moving. Now imagine FSD moving at 3 mph rather than zero. To me, that will feel very natural and very safe.

As a human driver, I rarely come to full stop like most people do here in California. I always think a 3-second stop for FSD is excessive. Even if a rolling stop is not permitted, it would be preferable to see the stop time cut to 1-1.5 seconds. Here in California at least , no specific stop time is mandated for a stop sign. Traffic code (CVC 22450) requires a "complete stop", meaning your vehicle's wheels must stop turning (zero speed) before proceeding, which is to eliminate rolling stops. The actual time depends on traffic, visibility, and pedestrians, but the key is a full pause to assess safety before proceeding. Stop time varies. In most cases, I think 1-1.5 seconds should be sufficient enough.

@tslaming @TeslaZoa @Tesla Do you know if there is a similar filing in progress in Korea and China?

BREAKING 🚨 Tesla’s "tabless" 4680 architecture: the final engineering blueprint 🔋 📜 On June 10, 2025, a quiet disclosure in Japan effectively handed the world the blueprints to a physics-defying engine. With the publication of patent application JP 2025-087870, Tesla has cracked open the black box of its 4680 cell, revealing the specific engineering logic designed to finally erase the "thermal bottleneck" that has plagued electric vehicles for decades. This document is far more than a legal formality; it serves as the missing technical manual for Tesla's next-generation power plant. It confirms the microscopic geometry that allows Tesla to radically scale up battery size without melting down the core—solving a fundamental thermal problem that has historically trapped the rest of the industry in much smaller, less efficient form factors. ⏳ Strategic timing: the Panasonic connection The timing of this Japanese filing is no accident—it is a calculated defensive move. As partner Panasonic ramps up 4680 production in Wakayama and Kansas, Tesla is moving to lock down its specific "shingled" electrode geometry under Japanese law. This establishes a formidable IP moat, preventing competitors from bypassing Tesla's design with minor tweaks. Simultaneously, it ensures that the millions of cells produced by its partners adhere strictly to this proprietary standard, guaranteeing uniformity across Tesla's global supply chain. ⚖️ The problem: the "Jellyroll" bottleneck To understand the breakthrough, one must understand the flaw in traditional lithium-ion manufacturing. Standard cells consist of a cathode, anode, and separator wound into a tight spiral known as a "jellyroll." Historically, manufacturers extracted electricity by welding a single metal tab to the end or middle of this roll, creating a severe choke point. Electrons were forced to travel horizontally along meters of spiraling foil just to reach that single exit. Since electrical resistance grows with distance, this long commute generated significant ohmic heat under heavy acceleration or fast charging. These "hot spots" degraded the battery and throttled performance, effectively placing a speed limit on how fast energy could move. 🔗 Tesla's solution: the continuous edge & insulated buffer Tesla’s patent details a radical architectural shift: removing the discrete tab entirely. Instead, the design utilizes the metal substrate itself—the current collector—as a massive, continuous interface. The patent specifies a precise coating strategy where the electrode is covered in active material, but with a critical modification at the edge. Crucially, the document describes a "First Portion"—a buffer zone located between the active chemical material and the bare metal edge. This strip is coated with a ceramic or polymer electrical insulator, acting as a vital safety guardrail. When the conductive edge is eventually bent over to close the cell, this insulation prevents the active anode or cathode material from touching the opposing electrode or the can, averting catastrophic short circuits. Beyond this safety buffer lies the "Second Portion," the exposed bare metal conductor. By utilizing this entire edge, Tesla creates a design where electrons no longer travel meters around the spiral, but only the short vertical distance of the cell height. This geometric shift reduces resistance by a factor of 5 to 20, effectively turning a dirt road into a high-speed electron highway. 📐 Mastering geometry and mechanics However, executing this concept isn't as simple as leaving a raw metal edge. Because the outer layers of a roll have a larger circumference than the inner layers, a straight strip of foil would crumple unpredictably when wound, leading to poor connectivity. The patent reveals Tesla's sophisticated solution: cutting the conductive edge into precise segments or "fingers." These segments are not uniform; they feature gradually increasing widths and spacing to account for the expanding diameter of the jellyroll. This mathematical precision ensures that when the cell is wound, the tabs align perfectly in a "shingled" or flower-like concentric pattern, creating a dense, flat surface ideal for welding. The connection is sealed by a specialized "First Cap" featuring spiral-shaped grooves designed to bite into these shingled foil ends, fused together via laser or ultrasonic welding to withstand the intense vibrations of the road. 🔥 Revolutionizing thermal management This precise mechanical structure unlocks a profound thermal advantage. In standard cells, heat is trapped in the core and must struggle radially through layers of insulating plastic separators to reach the cool outer wall. Tesla's "tabless" design flips this script. The continuous metal edge acts as a massive array of internal cooling fins, meaning the contact area between the electrode and the can is effectively the entire diameter of the cell. Heat can now travel axially—straight up the copper or aluminum foil—directly into the battery cap and cooling plate. This bypasses the thermal insulation of the separator entirely, allowing the 4680 cell to shed the immense heat of Supercharging instantly. 🚀 Enabling the future: structural packs & high-performance platforms Ultimately, these microscopic innovations serve as the foundation for Tesla's macroscopic goals. The patent describes the fundamental building block of the company's future vehicle architecture: 🔋 The Structural Battery Pack: By welding the shingled ends of the "tabless" electrode, the fragile jellyroll is transformed into a solid, rigid column. These cells are mechanically strong enough to be glued into a honeycomb block that doubles as the vehicle's floor. This mechanical rigidity is the key enabler for the Structural Battery Pack in the Model Y and Cybertruck, allowing Tesla to delete heavy steel body parts and drastically reduce weight. ⚡️ Unlocking Megawatt Charging: The "thermal highway" created by the continuous tab is the critical technology behind the Cybertruck and Tesla Semi’s ability to Supercharge at speeds of 350kW to 1MW+. Without this specific internal cooling path, a cell of this size would overheat immediately. This patent confirms that the 4680 is purpose-built to sustain the immense current throughput required for heavy-duty towing and hauling. 🚖 The Path to Robotaxi: Finally, the continuous roll-to-roll manufacturing method described—which eliminates the "stop-and-go" bottleneck of adding tabs—is what allows Tesla to produce cells at the velocity required for its next-generation unboxed assembly process. By reducing the cost per kWh through sheer speed, this patent lays the economic groundwork for the high-volume Robotaxi platform.

@yunta_tsai 3 mph. All I want for Christmas is to come to stop at just 3 mph. No more 0 mph stops.

It is under appreciated the fact that Tesla engineers are able to test Full Self-Driving at home, road trips, running errands — literally every second of their lives inside a Tesla. I went to a dinner once where a few people work at autonomous vehicle companies. They rarely put their butt in their own build, let alone drive them anywhere after work. Thus ride quality and experience are a myth to them. In contrast, we put our butt in the seat, literally “working ass off” every day, and getting unfiltered feedback from the spouses 😆.

테슬라 이게 무슨일이지.... 그림1. 테슬라의 동생 킴벌머스크가 12월 9일 테슬라의 주식 56,820주 매도했다라는 소식이 나왔습니다.. 킴벌머스크의 내부자매도에 인사이트를 얻기위해 저는 테슬라의 주식(남색)과 킴벌머스크의 매도위치(빨강원) 및 매도량(빨강)을 오버랩 시켰고 그 결과 2020년 12월 ~ 2025년 12월까지 총 8번의 매도 중에서 1번을 제외하고는 주가가 하락하기전 킴벌머스크가 매도했다라는 결과가 나왔습니다. 그림2. 킴벌 머스크가 매도를 한뒤에 몇일뒤에 어떠한 소식들이 있었는지 역사적으로도 한번 알아봤습니다. (이 부분이 시간이 제법 걸렸습니다. 뒷받침 되는 근거를 최선을 다해 알아봅니다. 틀린다고 할지언정 말이죠..) 이런것을 보면 킴벌머스크는 항상 특정 이벤트가 터지기에 앞서서 매도가 나왔다는 것을 볼 수 있습니다. 그리고 이번에도 어떠한 이벤트가 하락의 트리거가 될지 알 수는 없습니다. 하락이 안나오면 BEST 구요 그래도 저 나름대로 무엇이 트리거가 될수 있는지 미리 선행분석을 하였고, 어떻게 대응할지 등에 대해서 조사를 완료하였기에 혹여라도 궁금하시다면 참고 바랍니다. 비용은 하루에 400원밖에 하지 않지만, 제가 최선을 다할뿐더러 리서치 퀄리티도 충분히 만족스러울겁니다..! naver.me/IFGAhxj7

@yeoulabba A fresh perspective with facts to back up the claims makes a delightful reading. Thank you

20000 이만이라는 숫자 앞에 서서 문득 생각합니다. 사람은 왜 모이는가. 시장에는 물건을 사러 모이고, 광장에는 목소리를 내러 모입니다. 그런데 글 앞에는 왜 모일까요. 아무것도 사갈 수 없고, 아무것도 바꿀 수 없는데… 오래 생각했습니다. 그제야 알 것 같습니다. 제가 글을 잘 써서가 아닙니다. 같은 문장도 누가 읽느냐에 따라 전혀 다른 글이 됩니다. 제가 던진 한 줄에 여러분 각자의 삶이 스며들어, 이만 개의 서로 다른 이야기가 태어났습니다. 저는 씨앗을 뿌렸을 뿐, 꽃을 피운 것은 여러분의 마음입니다. 의사로서 삼십 년, 저는 치료가 의사 혼자 하는 일이 아님을 배웠습니다. 환자가 낫고자 하는 마음이 없으면 어떤 약도 소용없습니다. 글도 그렇습니다. 읽는 이의 마음이 열려 있지 않으면, 아무리 좋은 문장도 그저 활자일 뿐입니다. 그래서 고맙습니다. 글을 읽어주셔서가 아니라, 읽을 마음을 내어주셔서.

개인적으로 휴먼로이드 로봇이 운전을 한다는 생각은 경제성이 전혀 없다고 봄. 우리가 사업을 분석하고 Case들을 만드는 이유는 비교를 하기 위함. 차가 자동으로 움직일수 있는 차가 있는데, 다른 곳에서 뭔가를 생산하는데 기여해야 할 로봇에 차를 운전한다? 이 말만 들어도 상대적으로 경제성이 없다고 보지 않나? 따라서, 사업을 성공하려면 정확한 타게팅을 해야 함. 그렇지 않고, 이것 저것 다 하려고 하면 이도저도 안됨.

@JoeTegtmeyer The seats are attached to the floor bottom. In order to go through the opening of the body, the seats will have to be upright to minimize the opening size.

Am I seeing something incorrectly, or are the Cybercab seats folded forward in this image? Room behind the seats? Is this a change from the original prototype design?

FSD V14 problems I have encountered so far. 1) Stopped in the middle of a right-hand turn halfway and stopped with half of the car sticking out. 2) Much longer to make a lane change on a highway. At least 50% longer than 13.2.9 3) Indecision in making a lane change. Sometimes hesitates in the middle and comes back to the starting lane. 4) Cannot center in a parking space, parking forward after two tries. All these, besides the unnecessary constant lane changes and very cautious defensive brake stabs.

@TSLA_Bitcoin Wow, respect.
