Most cars in America have, at most, three colors of lights on the outside. There’s white for headlights and reverse lights, red for brake lights and rear lights plus, in some cars, amber for turn signals. Mercedes-Benz has just gotten approval to add a fourth color. Turquoise blue lights indicate when a Mercedes car is driving itself.
The article and the autoTLDR comment both say they were approved to use turquoise
Approved by who though?
It mentions an organization that has no authority over road laws in any US state, or EU, or anywhere else. So what?
The article says Nevada and California, I would assume it’s those states respective departments of transportation.
