TechCrunch Mobility: Blue-green is the color of autonomy
US safety regulators have proposed a common way to show when an autonomous vehicle is driving without a human monitoring the road. The proposal suggests cyan lights, which could make the vehicles easier for the public to identify as rules adapt to new designs.
The lights would be steady and visible from the front, rear and sides, but they would not be mandatory. The article also reports that GM plans to debut a new vehicle computing system and conversational AI in 2028, alongside hands-off, eyes-off highway driving; separately, Rivian has acquired UK AI startup Third Dimension to support simulation.
In short
- US regulators propose cyan lights to identify autonomous vehicles.
- The lights would be optional and steady, visible from all sides.
- GM plans new vehicle technology and highway automation for 2028.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
A shared cyan-light signal could help pedestrians, cyclists and other drivers recognise when an autonomous vehicle is operating without a human watching the road, supporting clearer expectations in public spaces. A common, optional standard could also give manufacturers flexibility while making future vehicles easier to identify as designs evolve.
The case against
A visible signal may create false confidence that a vehicle is safe or that people nearby should behave differently, even though the light cannot explain the vehicle’s capabilities or current limitations. Because the proposal is optional, inconsistent adoption could also leave the public unsure what the signal means, while adding little clarity where vehicles do not use it.
Explained simply
Autonomous vehicles use software and sensors to drive, and some can operate without a person watching the road. As these vehicles are tested and introduced, regulators are considering how people nearby can tell when a vehicle is driving itself.
In the US, federal safety regulators set rules for vehicles and are proposing a shared signal for this situation: steady cyan lights visible from several directions. The lights would be optional under the proposal, which reflects the challenge of setting common rules as vehicle designs and driving systems change.
The wider story involves carmakers adding more computing and AI to vehicles. General Motors has outlined plans for a future system that includes highway driving without hands or eyes on the road, while Rivian has bought British AI startup Third Dimension, whose work supports vehicle simulation.
