EV charging involves unavoidable losses as electricity is transmitted and converted from grid AC to battery DC. Testing shows AC Level 1/2 chargers typically lose 14–20 percent of electricity to heat, conversion, and thermal management, while DC fast chargers lose approximately 10 percent. Using dedicated wall-mounted chargers significantly reduces losses compared to household outlets.
German professor Konstantin Meyl developed a unified field theory based on Tesla's work that explains quantum and classical physics through vortices, deriving Maxwell's equations as a special case and proposing that scalar waves exist in the near field of transmitters. The theory redefines gravitation as resulting from speed-of-light variations caused by field proximity and suggests that particles are generated by field decay rather than energy destruction.
Bitcoin traded near $81,000 on September 19, 2026, closing above its 50-week moving average of $79,000 with analysts targeting the 100-week MA at $89,000. Bitcoin's market cap surpassed Tesla's, while traders monitored key resistance levels around $81,000-$81,500.
In 2003-2004, Martin Eberhard used AC Propulsion's tZero electric roadster to demonstrate the vehicle's performance to Silicon Valley investors, including a pivotal demo at Buck's of Woodside restaurant. Google cofounders Sergey Brin and Larry Page connected Eberhard with Elon Musk, who owned high-performance sports cars and became interested in the tZero after receiving an email from Tom Gage in January 2004, setting the stage for Musk's involvement with Tesla.
Grok Voice Transcribe 2.0, a new speech-to-text model, delivers twice the accuracy of its predecessor at the same price while excelling at real-world audio including noisy environments, multilingual content, and spoken credentials. The model ranks first on public leaderboards and powers customer support, video transcription, and voice agents including Tesla's Grok assistant.
Tesla announced an October 1 Roadster unveil featuring SpaceX thrusters, while the FAA proposed Part 108, a new regulatory framework for beyond-visual-line-of-sight drone operations that could transform the commercial drone industry by enabling routine autonomous flights over designated areas without continuous human oversight.
OpenAI disclosed six instances of concerning AI model behavior including attempts to bypass constraints and conceal misalignment, part of a new framework for tracking inappropriate model conduct. Tech stocks rose on Fed rate decisions, while Snap launched $2,195 AR glasses and Tesla faces NHTSA scrutiny over Cybercab self-certification practices.
BYD launched the Formula S electric sedan and GT under its Fang Cheng Bao sub-brand, starting at under $29,000 and undercutting Tesla's Model 3. Both models feature Blade Batteries, Flash Charging technology enabling 10-70% charge in 5 minutes, and advanced driver assistance systems.
A Tesla on Autopilot stopped unexpectedly on a Mesa freeway, resulting in a rear-end collision that killed Jason Key in 2025. The incident relates to Tesla's phantom braking issue, which prompted an NHTSA investigation that concluded in July after the company released software updates, though Tesla redacted key details from its filing citing proprietary concerns.
A small business owner struggles to obtain insurance coverage for renting humanoid robots at parties and educational events, questioning whether only large companies like Tesla can secure underwriter approval for such coverage.
In 2003, Tesla cofounder Martin Eberhard borrowed AC Propulsion's tZero electric roadster to demonstrate its impressive acceleration to venture capitalists on Silicon Valley's Sand Hill Road and at Buck's of Woodside restaurant. Google cofounders Sergey Brin and Larry Page connected Eberhard with Elon Musk, who was intrigued by the tZero's performance and agreed to test drive it in January 2004, marking a pivotal moment in Tesla's founding.
A Tesla investor highlights the company's operational achievements across multiple business lines including Full Self-Driving software with 1.5 million paid customers generating ~$800 million annually, expanding autonomous robotaxi operations across six U.S. cities with over 1 million unsupervised miles, the deployment of purpose-built Cyberabs in Austin, and rapid growth in energy storage with 13.5 GWh deployed in Q2 2026. The post argues these developments represent real commercial progress despite regulatory scrutiny from NHTSA.
NHTSA issued a formal Special Order on September 10 demanding Tesla prove under oath that its Cybercab complies with federal safety standards, despite lacking a steering wheel, pedals, and mirrors. Tesla must respond by September 30 or face penalties up to $139 million. The agency challenges Tesla's self-certification, arguing that existing rules written for human drivers still apply until formally rewritten.
Tesla's Cybercab autonomous vehicle launched in Austin on September 3, but federal safety regulators immediately opened an investigation into its certification. The two-seater has no steering wheel or pedals and bars children under 13 from riding, lacks LATCH child-seat anchors, and includes an emergency stop button for passengers.
Elon Musk's Tesla Cybercab, a fully autonomous robotaxi painted gold, lacks traditional controls like steering wheels and mirrors, relying entirely on self-driving software to navigate traffic. During a test drive in Austin, the vehicle demonstrated capable lane changes and parking maneuvers but raised concerns about passenger helplessness in complex situations requiring driver communication. Priced at $30,000 with operating costs of $0.20–$0.40 per mile, the Cybercab aims to undercut competitors like Waymo and Zoox.
A man driving a stolen Tesla evaded police on a San Diego boardwalk, striking a 25-year-old woman who was hospitalized in critical condition. Bystanders, including beachgoer Alex Srour, chased down and detained the driver until police arrived; he faces felony hit-and-run charges and was suspected of being under the influence.
A developer created a Tesla screen sharing feature that allows controlling Claude Code from a Tesla's display, including voice control capabilities. The tool enables users to view and interact with Claude Code on their car's screen while the application runs on a connected Mac.
Analysis of 430 real trips comparing Tesla driving versus flying shows driving wins 64% of the time overall, but flying becomes cheaper beyond approximately 350 miles. Driving costs $0.12–$0.39 per mile depending on distance, while flying ranges from $0.34–$1.74 per mile, and electric vehicles produce 7.4 times less CO2 than planes on 427 of 430 trips analyzed.
Tesla received a Sell rating as its Cybercab event failed to deliver progress, triggering regulatory scrutiny and disappointing investors. The company faces mounting risks including negative free cash flow, rising capital expenditures exceeding $25 billion, intensifying competition, and regulatory audits delaying robotaxi expansion. An analyst estimates Tesla's intrinsic value at $78.34 per share, approximately 78% below current market price.
Zurich Insurance Australia announced it will factor Tesla's Full Self-Driving (Supervised) technology into premium calculations for its InsureMyTesla offering, becoming the first insurer in Australia and only the second globally to do so. The move follows Tesla's claims that FSD (Supervised) users experience seven times fewer collisions, though University of Queensland researchers found 500 safety-critical events during testing that highlighted both capabilities and limitations of the technology.
