Tesla patent outlines system to actively monitor improper seatbelt use
Seatbelts have saved countless lives since they were introduced, especially after Swedish engineer Nils Bohlin invented the now-ubiquitous three-point seatbelt in 1958. Inasmuch as seatbelts are a proven safety system, however, it is still very easy to misuse them. One such example was demonstrated by Consumer Reports recently when the magazine decided to show exactly how drivers could trick Tesla’s Autopilot driver-monitoring systems.
In Consumer Reports‘ demonstration, the magazine’s testers tricked Tesla’s driver-monitoring system by buckling in the driver’s seatbelt without a person in the seat. After this, the magazine’s testers simply sat on top of the buckled seatbelt, effectively fooling the Model Y into thinking that its driver was wearing his seatbelt properly. Fortunately, it appears that Tesla is working on a way to prevent such tricks from happening. This was hinted at in a recently-granted patent that outlines a system that detects improper seatbelt use.
Published in 2019 and granted earlier this year, Tesla’s patent for “Improper Seatbelt Usage Detection” provides a good way for the company’s vehicles to accurately determine if its occupants are belted in properly. Tesla acknowledged the issue of drivers not wearing their seatbelts properly in the patent’s background.
“For safety-belt systems to be effective, seatbelts must be worn as intended. However, occupants do not always wear the seatbelts as intended. For example, occupants have been observed wearing the shoulder belt portion belt behind their backs, the shoulder belt portion under their arms, or hold another occupant on their lap. Current monitoring systems cannot determine whether an occupant is properly using a seatbelt. Thus, there is a need for a system that detects improper use of seatbelt,” Tesla wrote.
Tesla’s patent utilizes sensor modules to ensure that occupants are wearing their seatbelts correctly. These sensor modules could comprise more than one sensor, and they could be embedded within a vehicle’s seats. Some sensor modules also utilize inertial sensors or radio-frequency (RF) beacons, which would allow vehicles to determine if seatbelts are being used as designed. A controller that receives signals from the sensors and determines proper or improper seatbelt usage is also mentioned in the patent. This, as hinted at by Tesla’s illustrations in the patent, is extremely pertinent for vehicles that could operate without active human input.
In the patent’s discussion, Tesla notes that the system’s controller includes an associated memory that can store data regarding the vehicle’s use. This data includes occupant profiles, such as information on weight, height, and general posture, among others. What is rather remarkable is that Tesla’s patent is designed to detect even casual improper seatbelt use, such as when drivers place the shoulder belt under their arm, or when passengers hold a non-belted occupant on their lap. The EV maker outlined what happens in the vehicle if improper seatbelt use is determined.
“After determining improper usage of seatbelt 306, controller 404 may issue a warning, a notification, sound an alarm, or may even not allow to operate vehicle 100 until seatbelt 306 is used properly. A warning may be a text message displayed on display system of vehicle infotainment system, or an alarm sounding on vehicle infotainment system, a text message to registered mobile number of occupant, etc. Controller 404 may perform any other type of follow up actions as well to ensure proper usage of seatbelt 306 while driving vehicle 100. The present disclosure is not limited by any such follow up actions in any manner,” Tesla wrote.
With such systems in place, Tesla could highlight its place as the maker of the world’s safest vehicles. Teslas are already safe to begin with, thanks to their all-electric design that gives them a low center of gravity and generous crumple zones. But with a slew of systems such as Autopilot and improper seatbelt detection systems, perhaps it would not be long before professional auto testers like Consumer Reports can no longer trick Tesla’s safety features successfully.

Tesla Robotaxi’s biggest rival sends latest statement with big expansion
The new expanded geofence now covers a broader region of Austin and its metropolitan areas, extended south to Manchaca and north beyond US-183.
Tesla Robotaxi’s biggest rival sent its latest statement earlier this month by making a big expansion to its geofence, pushing the limits up by over 50 percent and nearing Tesla’s size.
Waymo announced earlier this month that it was expanding its geofence in Austin by slightly over 50 percent, now servicing an area of 140 square miles, over the previous 90 square miles that it has been operating in since July 2025.
Tesla CEO Elon Musk shades Waymo: ‘Never really had a chance’
The new expanded geofence now covers a broader region of Austin and its metropolitan areas, extended south to Manchaca and north beyond US-183.
These rides are fully driverless, which sets them apart from Tesla slightly. Tesla operates its Robotaxi program in Austin with a Safety Monitor in the passenger’s seat on local roads and in the driver’s seat for highway routes.
It has also tested fully driverless Robotaxi services internally in recent weeks, hoping to remove Safety Monitors in the near future, after hoping to do so by the end of 2025.

Although Waymo’s geofence has expanded considerably, it still falls short of Tesla’s by roughly 31 square miles, as the company’s expansion back in late 2025 put it up to roughly 171 square miles.
There are several differences between the two operations apart from the size of the geofence and the fact that Waymo is able to operate autonomously.
Waymo emphasizes mature, fully autonomous operations in a denser but smaller area, while Tesla focuses on more extensive coverage and fleet scaling potential, especially with the potential release of Cybercab and a recently reached milestone of 200 Robotaxis in its fleet across Austin and the Bay Area.
However, the two companies are striving to achieve the same goal, which is expanding the availability of driverless ride-sharing options across the United States, starting with large cities like Austin and the San Francisco Bay Area. Waymo also operates in other cities, like Las Vegas, Los Angeles, Orlando, Phoenix, and Atlanta, among others.
Tesla is working to expand to more cities as well, and is hoping to launch in Miami, Houston, Phoenix, Las Vegas, and Dallas.

Tesla automotive will be forgotten, but not in a bad way: investor
It’s no secret that Tesla’s automotive division has been its shining star for some time. For years, analysts and investors have focused on the next big project or vehicle release, quarterly delivery frames, and progress in self-driving cars. These have been the big categories of focus, but that will all change soon.
Entrepreneur and Angel investor Jason Calacanis believes that Tesla will one day be only a shade of how it is recognized now, as its automotive side will essentially be forgotten, but not in a bad way.

I subscribed to Tesla Full Self-Driving after four free months: here’s why
Eventually, and even now, the focus has been on real-world AI and Robotics, both through the Full Self-Driving and autonomy projects that Tesla has been working on, as well as the Optimus program, which is what Calacanis believes will be the big disruptor of the company’s automotive division.
On the All-In podcast, Calcanis revealed he had visited Tesla’s Optimus lab earlier this month, where he was able to review the Optimus Gen 3 prototype and watch teams of engineers chip away at developing what CEO Elon Musk has said will be the big product that will drive the company even further into the next few decades.
Calacanis said:
“Nobody will remember that Tesla ever made a car. They will only remember the Optimus.”
He added that Musk “is going to make a billion of those.”
Musk has stated this point himself, too. He at one point said that he predicted that “Optimus will be the biggest product of all-time by far. Nothing will even be close. I think it’ll be 10 times bigger than the next biggest product ever made.”
He has also indicated that he believes 80 percent of Tesla’s value will be Optimus.
Optimus aims to totally revolutionize the way people live, and Musk has said that working will be optional due to its presence. Tesla’s hopes for Optimus truly show a crystal clear image of the future and what could be possible with humanoid robots and AI.

Tesla Robotaxi fleet reaches new milestone that should expel common complaint
There have been many complaints in the eight months that the Robotaxi program has been active about ride availability, with many stating that they have been confronted with excessive wait times for a ride, as the fleet was very small at the beginning of its operation.
Tesla Robotaxi is active in both the Bay Area of California and Austin, Texas, and the fleet has reached a new milestone that should expel a common complaint: lack of availability.
It has now been confirmed by Robotaxi Tracker that the fleet of Tesla’s ride-sharing vehicles has reached 200, with 158 of those being available in the Bay Area and 42 more in Austin. Despite the program first launching in Texas, the company has more vehicles available in California.
The California area of operation is much larger than it is in Texas, and the vehicle fleet is larger because Tesla operates it differently; Safety Monitors sit in the driver’s seat in California while FSD navigates. In Texas, Safety Monitors sit in the passenger’s seat, but will switch seats when routing takes them on the highway.
Tesla has also started testing rides without any Safety Monitors internally.

This new milestone confronts a common complaint of Robotaxi riders in Austin and the Bay, which is vehicle availability.

With that being said, there have been some who have said wait times have improved significantly, especially in the Bay, where the fleet is much larger.
Robotaxi wait times here in Silicon Valley used to be around 15 minutes for me.
Over the past few days, they’ve been consistently under five minutes, and with scaling through the end of this year, they should drop to under two minutes. pic.twitter.com/Kbskt6lUiR

Tesla’s approach to the Robotaxi fleet has been to prioritize safety while also gathering its footing as a ride-hailing platform.
Of course, there have been and still will be growing pains, but overall, things have gone smoothly, as there have been no major incidents that would derail the company’s ability to continue developing an effective mode of transportation for people in various cities in the U.S.
Tesla plans to expand Robotaxi to more cities this year, including Miami, Las Vegas, and Houston, among several others.
