Tesla’s electric cars are known for being extremely quick, and they are also known for being extremely safe. The Model 3, the company’s most affordable car to date, for example, has aced safety ratings across the globe, earning a 5-Star rating from the NHTSA in the US, the Euro NCAP in Europe, and the ANCAP in Australia. Even the IIHS gave the Tesla Model 3 its highest rating, Top Safety Pick+

But this is Tesla, and the electric car maker is known for being a company that refuses to stay still. Its cars are already quick enough to give passengers serious Gs while launching, yet the company remains hard at work on making them even quicker and more visceral in terms of speed (e.g. the Model S Plaid Powertrain). In the same light, while Teslas are already safe at their current state, it is no surprise that the company remains dedicated to finding ways to make its vehicles even safer, both for passengers in the cabin and for pedestrians on the road.

One such example of this was highlighted in a recently published patent that was simply titled “Hinge Assembly for a Vehicle Hood.” Based on the electric car maker’s discussion, the novel hinge assembly has the potential to protect pedestrians who happen to hit the vehicle’s hood during a collision. Similar systems are in place in vehicles today, though Tesla maintained that conventional designs have lots of areas for improvement.

“Modern vehicles are mandated by safety standards to protect pedestrians from head-impact injuries, including a scenario in which a pedestrian would contact the vehicle’s hood. To meet these requirements. Current state of the art safety systems are active systems that typically include a sensor system to detect a collision with pedestrian and fire (using a pyrotechnic) an actuator to lift the front hood into a protective position before pedestrian impact. However, such systems may be falsely triggered and can only be used once because the pyrotechnic is not reversible. The pyrotechnic is also expensive, adding to overall cost of the vehicle. Therefore, there is a need for a safety system that overcomes the aforementioned drawbacks.”

Tesla noted in its patent’s description that its hinge assembly includes a body member and a hood member, with the latter being “pivotally coupled with a body member through a pivot pin.” In the event of a collision, a portion of the vehicle’s hood member or body member “deforms such that the hood member or body member disengages from the pivot pin.” This allows Tesla to use the hinge as a passive pedestrian safety system that does not require any additional components such as sensors or controllers. The design outlined in Tesla’s patent is also more practical than the pyrotechnic system used in conventional pedestrian impact safety systems. 

Tesla describes how its hood hinge works in a collision in the following section.

“FIG. 6 illustrates impact of a headform 602 on hinge assembly 116. Headform 602 represents the head (or portion thereof) of a pedestrian or other living being. As illustrated, when a collision occurs such that headform 602 hits a portion of hood member 108 of vehicle 100 along direction of an axis X-X′, a force is generated. When the force is great enough, the impact force causes hood member 108 to disengage from hinge assembly 116. The impact force typically causes deformation of portion 314 of hood member 108 adjacent to notch 312 such that pivot pin 202 disengages with second opening 304 of hood member 108. In embodiments, the width W of notch 312 is altered to change the impact force at which the hood member 108 disengages from hood member 108. In embodiments the impact force causes deformation of the pivot pin 202 to allow disengagement of hood member 108 from body member 110.

“In an event of collision, hood member 108 may disengage with hinge assembly 116 such that safety standards can be met. Hood member 108 may move down due to impact force and disengagement with hinge assembly 116. To allow movement of hood member 108, sufficient space may be provided by trimming away portions of hood member 108 and body member 110. Advantageously, this would lower weight of components while maintaining the safety standards for vehicle 100.”

Tesla is a carmaker that will likely never stay still. Despite its significant lead in the electric car segment thanks to its vehicles’ batteries and powertrain, Tesla is in a continuous process of improvement. The hood hinge outlined in this patent might be quite simple, but it contributes to the overall safety of Tesla’s lineup of vehicles nonetheless. Such initiatives, if any, further prove that when it comes to safety, no part is too small for innovation — and in the event of a collision, it’s these factors that can make all the difference.

Tesla Insurance officially expands to new U.S. state

Tesla’s in-house Insurance program first launched back in late 2019, offering a new way to insure the vehicles that was potentially less expensive and could alleviate a lot of the issues people had with claims, as the company could assess and repair the damage itself.

Tesla Insurance has officially expanded to a new U.S. state, its thirteenth since its launch in 2019.

Tesla has confirmed that its in-house Insurance program has officially made its way to Florida, just two months after the company filed to update its Private Passenger Auto program in the state. It had tried to offer its insurance program to drivers in the state back in 2022, but its launch did not happen.

Instead, Tesla refiled the paperwork back in mid-October, which essentially was the move toward initiating the offering this month.

Tesla’s in-house Insurance program first launched back in late 2019, offering a new way to insure the vehicles that was potentially less expensive and could alleviate a lot of the issues people had with claims, as the company could assess and repair the damage itself.

It has expanded to new states since 2019, but Florida presents a particularly interesting challenge for Tesla, as the company’s entry into the state is particularly noteworthy given its unique insurance landscape, characterized by high premiums due to frequent natural disasters, dense traffic, and a no-fault system.

Annual average premiums for Florida drivers hover around $4,000 per year, well above the national average. Tesla’s insurance program could disrupt this, especially for EV enthusiasts. The state’s growing EV adoption, fueled by incentives and infrastructure development, aligns perfectly with Tesla’s ecosystem.

Moreover, there are more ways to have cars repaired, and features like comprehensive coverage for battery damage and roadside assistance tailored to EVs address those common painpoints that owners have.

However, there are some challenges that still remain. Florida’s susceptibility to hurricanes raises questions about how Tesla will handle claims during disasters.

Looking ahead, Tesla’s expansion of its insurance program signals the company’s ambition to continue vertically integrating its services, including coverage of its vehicles. Reducing dependency on third-party insurers only makes things simpler for the company’s automotive division, as well as for its customers.

Tesla Full Self-Driving gets sparkling review from South Korean politician

“Having already ridden in an unmanned robotaxi, the novelty wasn’t as strong for me, but it drives just as well as most people do. It already feels like a completed technology, which gives me a lot to think about.”

Tesla Full Self-Driving got its first sparkling review from South Korean politician Lee So-young, a member of the country’s National Assembly, earlier this week.

Lee is a member of the Strategy and Finance Committee in South Korea and is a proponent of sustainable technologies and their applications in both residential and commercial settings. For the first time, Lee was able to utilize Tesla’s Full Self-Driving technology as it launched in the country in late November.

Her thoughts on the suite were complimentary to the suite, stating that “it drives just as well as most people do,” and that “it already feels like a completed technology.”

Her translated post says:

“Finally, today I got to experience Tesla FSD in Seoul. Thanks to the Model S sponsored by JiDal Papa^^, I’m truly grateful to Papa. The route was from the National Assembly -> Mangwon Market -> Hongik University -> back to the National Assembly. Having already ridden in an unmanned robotaxi, the novelty wasn’t as strong for me, but it drives just as well as most people do. It already feels like a completed technology, which gives me a lot to think about. Once it actually spreads into widespread use, I feel like our daily lives are going to change a lot. Even I, with my license gathering dust in a drawer, don’t see much reason to learn to drive a manual anymore.”

Tesla Full Self-Driving officially landed in South Korea in late November, with the initial launch being one of Tesla’s most recent, v14.1.4.

It marked the seventh country in which Tesla was able to enable the driver assistance suite, following the United States, Puerto Rico, Canada, China, Mexico, Australia, and New Zealand.

It is important to see politicians and figures in power try new technologies, especially ones that are widely popular in other regions of the world and could potentially revolutionize how people travel globally.

Tesla dispels reports of ‘sales suspension’ in California

“This was a “consumer protection” order about the use of the term “Autopilot” in a case where not one single customer came forward to say there’s a problem.

Sales in California will continue uninterrupted.”

Tesla has dispelled reports that it is facing a thirty-day sales suspension in California after the state’s Department of Motor Vehicles (DMV) issued a penalty to the company after a judge ruled it “misled consumers about its driver-assistance technology.”

On Tuesday, Bloomberg reported that the California DMV was planning to adopt the penalty but decided to put it on ice for ninety days, giving Tesla an opportunity to “come into compliance.”

Tesla enters interesting situation with Full Self-Driving in California

Tesla responded to the report on Tuesday evening, after it came out, stating that this was a “consumer protection” order that was brought up over its use of the term “Autopilot.”

The company said “not one single customer came forward to say there’s a problem,” yet a judge and the DMV determined it was, so they want to apply the penalty if Tesla doesn’t oblige.

However, Tesla said that its sales operations in California “will continue uninterrupted.”

It confirmed this in an X post on Tuesday night:

The report and the decision by the DMV and Judge involved sparked outrage from the Tesla community, who stated that it should do its best to get out of California.

One X post said California “didn’t deserve” what Tesla had done for it in terms of employment, engineering, and innovation.

Tesla has used Autopilot and Full Self-Driving for years, but it did add the term “(Supervised)” to the end of the FSD suite earlier this year, potentially aiming to protect itself from instances like this one.

This is the first primary dispute over the terminology of Full Self-Driving, but it has undergone some scrutiny at the federal level, as some government officials have claimed the suite has “deceptive” naming. Previous Transportation Secretary Pete Buttigieg was vocally critical of the use of the name “Full Self-Driving,” as well as “Autopilot.”
