Mysterious New Road Signs Appear Across Europe – What Do They Mean?

New black and white road signs are appearing across Europe, causing confusion among drivers as they are not found in any driving manual. These signs are not intended for humans, but for autonomous vehicles. They function as an additional layer of location accuracy, supplementing data from GPS, cameras, and sensors. The software in autonomous vehicles 'reads' the signs to precisely determine their position, essential for lane changes and real-time reactions. Germany, a pioneer in autonomous driving, has launched a pilot program with these signs, while Greece is also taking steps towards integrating autonomous vehicles.
