AI-powered Tesla traffic light device intrigues Elon

Could Tesla develop their own traffic light?

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 Increases Price of Model S; Starts Offering Free Lifetime Supercharging

Not a Tesla App

For the first time in quite a while, Tesla has increased the price of one of its vehicle offerings. The Model S Long Range and the Model S Plaid have both received a hefty price increase. However, not all is bad - as Tesla also added a new benefit for buyers.

Price Increase

The price increase for the Model S is $5,000 - currently only in the United States. This price increase will likely impact other markets, including Canada, in the coming days.

The Model S Long Range now starts at $79,990, while the Model S Plaid now starts at $94,990. The Model S and Model X now have the same starting price. Interestingly, that’s also the same pricing point for the Cybertruck AWD and Cyberbeast Trimotor non-Foundation Series. 

The vehicle configuration does not appear to have changed, so the new pricing is simply an increase rather than the addition or removal of features. Tesla previously cut the price of the Model S and Model X by 15% in 2023, so this could simply be an adjustment to ensure that the vehicle pricing stays in line with inflation and other factors.

Free Lifetime Supercharging

For those on the fence about ordering a Model S, Tesla has brought back Free Lifetime Supercharging when you order a new Model S on or after December 13, 2024. As always, Free Lifetime Supercharging is restricted to the buyer’s Tesla account and to that specific vehicle. It cannot be transferred to another vehicle or another owner after ownership transfer. It’s worth noting, that it also doesn’t exclude the owner from receiving Supercharger idle fees or congestion fees. There is currently no end date for this promotion.

There are currently no changes to the Model X, neither a price increase nor the addition of Lifetime Superchargering. However, when Tesla makes changes to one of their premium vehicles, it usually affects the other one as well. So be on the lookout for potential changes to the Model X offering in the coming days.

We’ve seen Tesla value Lifetime Supercharging at $5,000, so this falls in line with the price increase we’re seeing. It’s possible that Tesla will begin to bring back Lifetime Supercharging as a perk for buying into their more premium Model S and Model X cars, or this could be another temporary promotion to get buyers who are on the fence to go ahead and make their purchase while this promotion lasts.

Tesla’s Optimus Robot Learns to Walk Without Vision [VIDEO]

Optimus Falls - but catches itself!

Not a Tesla App

Tesla recently showed off a demo of Optimus, its humanoid robot, walking around in moderately challenging terrain—not on a flat surface but on dirt and slopes. These things can be difficult for a humanoid robot, especially during the training cycle.

A Look Behind the Curtain

Most interestingly, Milan Kovac, VP of Engineering for Optimus, clarified what it takes to get Optimus to this stage. Let’s break down what he said.

Optimus is Blind

Optimus is getting seriously good at walking now - it can keep its balance over uneven ground - even while walking blind. Tesla is currently using just the sensors, all powered by a neural net running on the embedded computer. 

Essentially, Tesla is building Optimus from the ground up, relying on as much additional data as possible while it trains vision. This is similar to how they train FSD on vehicles, using LiDAR rigs to validate the vision system’s accuracy. While Optimus doesn’t have LiDAR, it relies on all those other sensors on board, many of which will likely become simplified as vision takes over as the primary sensor.

Today, Optimus is walking blind, but it’s able to react almost instantly to changes in the terrain underneath it, even if it falls or slips. 

What’s Next?

Next up, Tesla AI will be adding vision to Optimus - helping complete the neural net. Remember, Optimus runs on the same overall AI stack as FSD - in fact, Optimus uses an FSD computer and an offshoot of the FSD stack for vision-based tasks.

Milan mentions they’re planning on adding vision to help the robot plan ahead and improve its walking gait. While the zombie shuffle is iconic and a little bit amusing, getting humanoid robots to walk like humans is actually difficult.

There’s plenty more, too - including better responsiveness to velocity and direction commands and learning to fall and stand back up. Falling while protecting yourself to minimize damage is something natural to humans - but not exactly natural to something like a robot. Training it to do so is essential in keeping the robot, the environment around it, and the people it is interacting with safe.

We’re excited to see what’s coming with Optimus next because it is already getting started in some fashion in Tesla’s factories.
