Germany-based Mercedes-Benz unveiled its Concept GLA compact SUV at the Shanghai auto show in April. The car’s front headlights each feature a laser beam that can project pictures or video from a smartphone, a hard drive or the Internet onto a screen or other surface. The company says the devices could improve road safety by projecting directional arrows onto the road to show where the driver is heading. The driving lights are the first to use a laser beam reflected off a mirror, Mercedes-Benz said. There is no official word on whether the 2015 production version of the vehicle will have lasers, however. The car also houses two high-definition cameras that can be used to take 3-D images as the car drives.
