Would Tesla consider creating their own AI-controlled traffic lights? There was an interesting exchange on Twitter about traffic lights that appeared to catch Elon Musk's interest.
The conversation circled around traffic lights and the amount of time and energy that is spent waiting at red lights when there is no traffic.
The traffic light was invented just as the popularity of cars started taking off in the early 1900s. The traffic light itself was first used in 1914, while vehicles became popular in the 1920s.
While there have been numerous improvements to traffic lights, they've been relatively small considering it's been more than a century since their introduction. We've seen improvements such as adding a yellow light to warn drivers of an upcoming red light, using LEDs for better visibility, adding different light combinations, and even using different light patterns based on the time of day.
However, we have the technology today to make traffic lights as we know them a thing of the past.
While traffic lights may seem like an odd business for Tesla to get into, it actually fits their mission and capabilities quite well.
Tesla would use cameras to build an AI system that would predict traffic patterns to reduce time spent and emissions produced at traffic lights.
"Maybe Tesla should make an AI vision device that plugs into these legacy traffic lights. It could just look at traffic & automatically maximize throughput."
-Elon Musk
They could even reduce accidents by figuring out the ideal time to wait before flipping the opposite traffic light green.
By Tesla using its core competencies to develop traffic lights it could further accelerate its mission of easing traffic and reducing vehicle emissions. It's a similar reason why they're developing robots.
AI we could practically eliminate waiting at a red light when there's no traffic in sight. It would also vastly speed up most intersections. Time is our most valuable asset, but we spend hours a year stopped at red lights. Just staring and waiting.
Well, apparently Elon Musk strongly agrees with us. When a Twitter user complained that it's mind-boggling the amount of time we collectively spend waiting at empty intersections, Elon replied with a simple "100%."
Elon then replied to another Twitter user expressing his interest that maybe Tesla should get into the traffic light business. Elon talked about the possibility of developing an add-on device for traffic lights. The device would use vision AI to turn legacy traffic lights into AI powerhouses that would maximize traffic throughput.
Here's hoping that this random tweet sparks other conversations at Tesla this morning. Making traffic lights smarter helps ease traffic and fits their competencies and mission perfectly.
I think when Tesla takes a closer look, they'll realize that they can do more than just maximize throughput and reduce waiting, but that they'll also be able to reduce accidents and frustrations that could come with dealing with traffic.
Tesla could eventually develop their own traffic light that would fix even more problems.
If Tesla developed an LED panel-based traffic light, they could even create dynamic traffic lights that would automatically use traffic arrows only when needed, and automatically and continuously adjust the types of traffic signals used based on traffic conditions over time.
An always-connected traffic light could also open up the way to city-controlled traffic lights that could prevent accidents in police chases or save lives by turning lights green for ambulances.
The possibilities are near endless and we could one day look back at those lonesome times when we used to stare up a red light waiting and hoping for it to finally be our turn.

Tesla has officially filed construction permits for its first Semi Megacharger site located near the 405 and 110 freeway corridors in California. This location is just outside Carson, CA, near the Port of Long Beach—one of the busiest ports in the U.S.
The site, located at 19300 S Hamilton Avenue, will primarily feature Megachargers designed to support Tesla’s electric truck fleet. Additionally, Tesla plans to include a small lounge facility with vending machines, restrooms, and other amenities for drivers.
Semi-Public
This site is considered “public” because it’s the first Megacharger location built on publicly accessible land, conveniently situated off a major highway. Previous Megacharger sites have been installed at private corporate facilities, making them inaccessible to the general public.
Despite being in a public location, Tesla plans to keep these Megacharger units exclusive to the Tesla Semi, unlike Superchargers, which are gradually opening to other EV manufacturers. While the Megacharger standard—MCS—is an open standard like NACS, Tesla’s Megachargers will remain off-limits to other trucks.
Megacharger
The Megacharger features a large, square-shaped connector, a sharp contrast to the NACS design. This is due to the unique operating specifications of the MCS connector, which supports charging between 750kW and 1,000kW. This incredible power could potentially add up to 400 miles (of the Semi’s 500-mile range) in just 30 minutes of charging.
With such rapid charging capabilities, the Tesla Semi’s downtime will be drastically reduced, allowing for more efficient operations and less time spent charging.
With volume production expected to begin in late 2025 or early 2026, the Tesla Semi is poised to become one of the company’s biggest products. We’re excited to see more Semis on the road—and hopefully, many more Megacharger sites in the near future.
The Cybertruck has finally received an official crash safety rating—and to the surprise of many critics, it’s outstanding. Tesla has announced that the Cybertruck earned a 5-star Overall Crash Safety Rating from the NHTSA.
Even more remarkable, the Cybertruck holds the lowest overall probability of injury and the lowest rollover risk of any pickup truck ever tested by the agency. Skeptics have long questioned its safety, arguing that its rigid design lacks crumple zones and could endanger occupants. But these results prove otherwise. Let’s break it down!
The Test
Sawyer Merritt
The 2024 and 2025 Tesla Cybertruck—both the AWD and Cyberbeast variants—were tested under the New Car Assessment Program (NCAP) standards, which evaluate vehicle crashworthiness and restraint systems through various types of impacts.
Tesla has long prioritized safety, not only through advancements in active safety with FSD but also by designing vehicles with robust structural protection. The Cybertruck incorporates the Cybercell structural battery and internal crash cans to improve crash performance.
Its front and rear Gigacastings are engineered to channel impact forces into internal structures that collapse, functioning similarly to crumple zones in traditional vehicles. This design directs energy away from occupants and critical components. First, the internal crash cans absorb the force, and if needed, the Gigacasting collapses—both of which are replaceable, making the Cybertruck more repairable when compared to other modern vehicles.
Euro NCAP
Sawyer Merritt
While the Cybertruck has now earned a North American NCAP rating, it has yet to receive a Euro NCAP rating. Tesla has not submitted the Cybertruck for testing in Europe, as its sharp-edged stainless steel panels do not currently meet European regulations.
Tesla does plan to bring the Cybertruck to Europe eventually, but doing so will likely require significant exterior modifications to soften its edges and comply with safety standards. Once those changes are made, the Cybertruck should have no trouble acing the Euro NCAP tests.
After such a long wait, it’s great to finally see the Cybertruck’s crash test results—and with a 5-star rating, Tesla deserves credit for its impressive engineering. Safety has always been a cornerstone of Tesla’s design philosophy, and the Cybertruck continues that tradition as one of the safest vehicles on the road.
