Mercedes-Benz unveils augmented reality heads-up display

Mercedes-Benz has unveiled revolutionary driver alertness technology and a new infotainment system due to debut on its flagship S-Class limousine next year before it eventually filters down to more affordable models. The technology is so advanced you may be able to make contactless payments using the car itself – which is why the new system is protected by a PIN code as well as fingerprints, facial recognition, or voice commands.
