The Blue Light Debate: Essentially a Lack of 'Grammar' in Smart Driving Interaction

For designers, news about regulations on the "blue lights" isn't surprising—it's the inevitable result of "interaction semantic dissonance" that was bound to happen sooner or later. When every company's autonomous driving signal light flashes differently, glows from different positions, and uses different colors to convey status, it’s not communicating information to the outside world; it’s creating cognitive noise. GB 4785-2019 is just the trigger. What really needs scrutiny is that in designing the digital dialogue between "car and human" or "car and car," we haven’t even standardized the most basic punctuation marks.
