Tesla expands the green traffic light bell – reducing road rage

Tesla expands the green traffic light bell - reducing road rage

Tesla is introducing a Green Light Chime feature, which was previously only intended for people with a fully autonomous driving (FSD) trial for most of its cars, which helps reduce road rage at traffic lights.

When Tesla began bringing traffic light controls into its cars equipped with the Full Autonomous Driving (FSD) package, the automaker introduced a feature that would recognize when a traffic light turns green and emit a tone to inform the driver.

With the new software update 2022.20, Tesla has expanded the feature to all cars equipped with autopilot when Traffic Light Control and Stop Light is activated:

The chime will be triggered when the traffic light you are waiting for turns green. If you are waiting behind another vehicle, the buzzer will sound as soon as the vehicle is advanced unless cruise control or Autosteer is active. When the traffic light is activated and the stop light is controlled, a chime will be triggered when you can confirm to continue via a green traffic light.

While the feature is being expanded, it appears that it will only work with vehicles equipped with PC 3.0 – also known as a self-driving computer – but it doesn’t appear that drivers need to purchase the expensive self-driving package to activate the feature.

Tesla writes about how to activate the feature:

To enable, tap Controls > Autopilot > Green traffic light chime.

In the release notes, the automaker notes that the chime is “designed only as a notification,” and it remains “the driver’s responsibility to monitor their environment and make decisions accordingly.”

Take Electric

I’ve had this feature for a while now, and I find it useful. When I’m arguing with my girlfriend at the red light, sometimes I don’t see when it turns green, and the ringer comes in handy.

Hopefully this helps reduce road rage because some people are quick to get upset when people don’t speed up right away when it turns green.

The next step will be to get a countdown to the green light – something that Audi has in some of its newer cars. I’ve tried it at e-tron in Sacramento, and it’s pretty cool. It only works in cities where the traffic light system supports integration, but there are a growing number of those. When you stop at a red light, a countdown timer appears on the instrument cluster that tells you when the light turns green.

Perhaps Tesla could add that in a future software update.
