Mercedes’ Turquoise Lights: A Beacon of Autonomous Driving

The future of autonomous vehicles goes beyond technology; it's about how they communicate with their surroundings. Mercedes' introduction of turquoise lights is a remarkable step towards creating a language of interaction on our roads, shaping the future of automated mobility


Mercedes-Benz is charting new territory in the realm of automated vehicle communication. The company’s latest innovation isn’t just a fancy gadget or a tech upgrade; it’s something more subtle yet potentially groundbreaking – turquoise lights. These lights serve as a signal to other road users, indicating that the vehicle is operating under Mercedes’ Drive Pilot automated system.

Why Turquoise Lights? Understanding the Signal

Typically, blue lights in your rearview mirror signal the approach of law enforcement, but Mercedes is repurposing this color spectrum for a different use. The turquoise lights on a Mercedes-Benz vehicle signal that the car is using Drive Pilot, Mercedes’ version of a near-autonomous driving system. This feature is a significant leap forward in self-driving technology available to consumers.

Drive Pilot: A New Era of Driving

Drive Pilot stands out in the market as the first system that allows drivers to go hands-free and eyes-free under certain conditions. It operates under specific circumstances: on approved highways, in traffic, at speeds under 40 mph, and in clear weather. Once activated, the car takes over the tedious aspects of driving – steering, braking, and accelerating in response to traffic, all while monitoring its surroundings with advanced sensors and cameras. It’s like an advanced cruise control for heavy traffic situations.

Unlike other systems such as GM’s Super Cruise or Ford’s BlueCruise, which require drivers to remain alert and watchful, Drive Pilot allows drivers more freedom. They can engage in other activities like reading or using the car’s touchscreen – although they must remain alert enough to retake control within 10 seconds if prompted by the system.

Legal and Public Perception Aspects

The introduction of turquoise lighting with Drive Pilot is more than a design choice; it’s a strategic move by Mercedes. It aims to enhance public acceptance and trust in automated driving technologies. Additionally, it provides a clear indicator for law enforcement and other road users, helping them understand the driver’s potential engagement in secondary activities, which remains a gray area legally.

Mercedes’ forward-thinking approach sets a new bar in the industry, which is still predominantly operating at Level 2 automation, even with Tesla’s ambitious claims about its “Full Self-Driving” feature. In this evolving landscape, Mercedes is paving the way for broader acceptance and understanding of automated driving features.

Beyond Mercedes: The Future of Autonomous Vehicle Interaction

The development of autonomous vehicles is not just about the technology that goes into the cars but also how these vehicles interact with their environment, including pedestrians and human drivers. Current road safety heavily relies on non-verbal cues like eye contact and gestures, which automated systems like robotaxis can’t replicate. However, companies are exploring innovative ways to bridge this gap.

For example, Waymo, a leader in the robotaxi field, has introduced communicative dome-shaped screens on its vehicles. These screens display messages and icons to convey the car’s intentions to pedestrians and other drivers, like yielding actions. This development is part of a broader industry trend towards creating a language of interaction between automated vehicles and their human counterparts.
