Ferrari and Stellantis offer front shotgun passengers an interactive screen to futz with. BMW and other brands dangle lavish multimedia streaming systems for the back. Now Hyundai Mobis—the parts and components arm of the South Korean automaker—has upped the ante with a quantum dot screen that rivals the performance of even top-shelf OLED tech but at a substantially discounted price.
