Elon Musk to speak next month at the TED conference – Not a Tesla App

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.

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.
