Tesla says ‘brake failure’ protestor vandalized Model 3, refused third-party testing
Tesla is navigating through a difficult bout with an owner in Shanghai, China, named Zhang Yazhou, who appeared at the Shanghai Auto Show last week in protest of what she claimed was a faulty Model 3 braking system. Tesla has now issued a more lengthy and detailed description of their encounters with Mrs. Zhang, revealing that she not only vandalized her own car with red spray paint, but she also denied any requests made by Tesla to have an independent, third-party company investigate whether the Model 3 had braking issues.
On April 19th, Zhang climbed on top of a Model 3 that was positioned at the Tesla booth at the Shanghai Auto Show. Wearing a shirt that said “Tesla Brake Failure,” Zhang yelled “Tesla brakes failed me” to a crowd of spectators who surrounded the all-electric sedan. As a result, Tesla has released several responses, including data from the accident that showed the driver, who was actually Zhang’s father, was driving at a speed that was above the posted speed limit and engaged the braking system successfully on more than 40 occasions in the half-hour leading up to the accident.
Now, Tesla is making more attempts to reveal the story to the public and is revealing its interactions with Zhang.

On Tesla’s official Weibo page, the company stated that Zhang talked to Tesla on April 27th, and the automaker was willing to continue communicating and try to come to a solution. After a five-day stint with the Police following the protest, Zhang returned home and told Tesla reps, “I just came back. I need to adjust. I hope you can show an attitude that really solves the problem. When you have this attitude, we will communicate.”
Tesla revealed that Zhang was in the passenger’s seat during the accident and that traffic police came to the conclusion that the driver, Zhang’s father, was “fully responsible for the accident because he did not maintain a safe distance from the vehicle in front.” After the vehicle arrived at a local service shop for repairs on February 22, Tesla says Ms. Zhang put a seal on the vehicle three days after its arrival so nobody could enter the car. Tesla says that Zhang believed the vehicle’s data could be tampered with, and this was the reason for the seal being placed on the doors. Zhang had the still-wrecked vehicle towed to Tesla’s Zhengzhou Fotamen showroom on March 5th, where it would be sitting in the public for everyone to see.

The following day, Zhang placed a banner that read “Brake Failure” on the car, and Tesla began offering Zhang the option of having third-party inspectors take a look at the car on their dime. Zhang refused, saying that she was not interested in having the car looked at by “non-accredited third-party testing agencies,” and warned that Tesla should “look for pressure from the media” if the car wasn’t returned.

Zhang then came back to the showroom where her car was located and spraypainted the exterior of her wrecked Model 3 with red paint. The words once again said, “Brake Failure.”
“The Tesla staff are still actively communicating with Ms. Zhang, trying to find a solution, and negotiating with her husband, Mr. Li, hoping to minimize the impact and help her maximize the benefits within a reasonable range. Mr. Li made it clear that he still has a “team” from Beijing assisting him, and being helped by others in “cooperating” with others can only be obedient,” Tesla added. Zhang resealed her vehicle on March 21st.

According to Tesla, Zhang then had the car towed to the Zhengzhou Dahe Auto Show, where two hired models stood beside the car. Zhang then made her appearance at the Shanghai Auto Show on April 19th. Tesla says that it is still working to iron out the situation and work with Zhang and her husband, who is identified as Mr. Li. Tesla sent a sealed version of the vehicle data that was available 30 minutes before the accident occurred to Zhang’s house.
“Since February, we have been doing our best to actively communicate with Ms. Zhang and her family. We sincerely hope that we can promote vehicle inspection as soon as possible and give a result to the friends who care about Tesla,” the company concluded.

Waymo scrutinized after self-driving taxis cause traffic jams during SF blackout
It’s not farfetched to speculate that it would have been a doomsday scenario for Tesla had FSD behaved this way.
A power outage across San Francisco over the weekend forced numerous Waymo self-driving taxis to stop at darkened intersections and cause traffic blockages in multiple locations across the city. The disruption left riders stranded, frustrated drivers blocked, and city officials stepping in as the Alphabet-owned company temporarily suspended service amid the widespread gridlock.
Needless to say, it would likely have been a doomsday scenario for Tesla had FSD behaved in a similar way, especially if fleets of its robotaxis blocked traffic for numerous drivers.
Power outage halts Waymo fleet
The outage knocked out electricity for tens of thousands of customers, leaving traffic signals dark across large parts of the city, as noted in a report from the New York Times. Waymo vehicles began stopping at intersections and remained stationary for extended periods, seemingly unable to operate. Tow truck operators worked through the night removing immobilized vehicles, while videos circulated online showing Waymos with hazard lights flashing as traffic backed up around them.
Waymo later confirmed that it had paused its Bay Area ride-hailing service after the San Francisco mayor’s office contacted the company about the congestion its vehicles were contributing to. Service began coming back online shortly after 3:30 p.m. local time, though some users still reported being unable to request rides. Waymo maintained that no injuries or accidents were reported during the outage.
Autonomous cars during emergencies
The incident surprised industry observers since autonomous vehicles are designed to function during signal outages and temporary connectivity losses. Waymo stated that its vehicles treat nonfunctional signals as four-way stops, but “the sheer scale of the outage led to instances where vehicles remained stationary longer than usual to confirm the state of the affected intersections. This contributed to traffic friction during the height of the congestion.” Experts suggested the problem may have been linked to the vehicles’ reliance on remote assistance teams, which help resolve complex situations the cars cannot handle independently.
“Yesterday’s power outage was a widespread event that caused gridlock across San Francisco, with non-functioning traffic signals and transit disruptions. While the failure of the utility infrastructure was significant, we are committed to ensuring our technology adjusts to traffic flow during such events,” the Waymo spokesperson stated, adding that it is “focused on rapidly integrating the lessons learned from this event, and are committed to earning and maintaining the trust of the communities we serve every day.”

Tesla aims to combat common Full Self-Driving problem with new patent
Tesla writes in the patent that its autonomous and semi-autonomous vehicles are heavily reliant on camera systems to navigate and interact with their environment.
Tesla is aiming to combat a common Full Self-Driving problem with a new patent.
One issue with Tesla’s vision-based approach is that sunlight glare can become a troublesome element of everyday travel. Full Self-Driving is certainly an amazing technology, but there are still things Tesla is aiming to figure out with its development.
Unfortunately, it is extremely difficult to get around this issue, and even humans need ways to combat it when they’re driving, as we commonly use sunglasses or sun visors to give us better visibility.
Cameras obviously do not have these ways to fight sunglare, but a new patent Tesla recently had published aims to fight this through a “glare shield.”
Tesla writes in the patent that its autonomous and semi-autonomous vehicles are heavily reliant on camera systems to navigate and interact with their environment.

The ability to see surroundings is crucial for accurate performance, and glare is one element of interference that has yet to be confronted.
Tesla described the patent, which will utilize “a textured surface composed of an array of micro-cones, or cone-shaped formations, which serve to scatter incident light in various directions, thereby reducing glare and improving camera vision.”

The patent was first spotted by Not a Tesla App.
The design of the micro-cones is the first element of the puzzle to fight the excess glare. The patent says they are “optimized in size, angle, and orientation to minimize Total Hemispherical Reflectance (THR) and reflection penalty, enhancing the camera’s ability to accurately interpret visual data.”
Additionally, there is an electromechanical system for dynamic orientation adjustment, which will allow the micro-cones to move based on the angle of external light sources.
This is not the only thing Tesla is mulling to resolve issues with sunlight glare, as it has also worked on two other ways to combat the problem. One thing the company has discussed is a direct photon count.
CEO Elon Musk said during the Q2 Earnings Call:
“We use an approach which is direct photon count. When you see a processed image, so the image that goes from the sort of photon counter — the silicon photon counter — that then goes through a digital signal processor or image signal processor, that’s normally what happens. And then the image that you see looks all washed out, because if you point the camera at the sun, the post-processing of the photon counting washes things out.”
Future Hardware iterations, like Hardware 5 and Hardware 6, could also integrate better solutions for the sunglare issue, such as neutral density filters or heated lenses, aiming to solve glare more effectively.

Delaware Supreme Court reinstates Elon Musk’s 2018 Tesla CEO pay package
The unanimous decision criticized the prior total rescission as “improper and inequitable,” arguing that it left Musk uncompensated for six years of transformative leadership at Tesla.
The Delaware Supreme Court has overturned a lower court ruling, reinstating Elon Musk’s 2018 compensation package originally valued at $56 billion but now worth approximately $139 billion due to Tesla’s soaring stock price.
The unanimous decision criticized the prior total rescission as “improper and inequitable,” arguing that it left Musk uncompensated for six years of transformative leadership at Tesla. Musk quickly celebrated the outcome on X, stating that he felt “vindicated.” He also shared his gratitude to TSLA shareholders.
Delaware Supreme Court makes a decision
In a 49-page ruling Friday, the Delaware Supreme Court reversed Chancellor Kathaleen McCormick’s 2024 decision that voided the 2018 package over alleged board conflicts and inadequate shareholder disclosures. The high court acknowledged varying views on liability but agreed rescission was excessive, stating it “leaves Musk uncompensated for his time and efforts over a period of six years.”
The 2018 plan granted Musk options on about 304 million shares upon hitting aggressive milestones, all of which were achieved ahead of time. Shareholders overwhelmingly approved it initially in 2018 and ratified it once again in 2024 after the Delaware lower court struck it down. The case against Musk’s 2018 pay package was filed by plaintiff Richard Tornetta, who held just nine shares when the compensation plan was approved.
A hard-fought victory
As noted in a Reuters report, Tesla’s win avoids a potential $26 billion earnings hit from replacing the award at current prices. Tesla, now Texas-incorporated, had hedged with interim plans, including a November 2025 shareholder-approved package potentially worth $878 billion tied to Robotaxi and Optimus goals and other extremely aggressive operational milestones.
The saga surrounding Elon Musk’s 2018 pay package ultimately damaged Delaware’s corporate appeal, prompting a number of high-profile firms, such as Dropbox, Roblox, Trade Desk, and Coinbase, to follow Tesla’s exodus out of the state. What added more fuel to the issue was the fact that Tornetta’s legal team, following the lower court’s 2024 decision, demanded a fee request of more than $5.1 billion worth of TSLA stock, which was equal to an hourly rate of over $200,000.
