Audi announces A2 electric concept car, uses lasers to ensure safety of future humans

Lasers make everything better, including (but not limited to): microphones, kidneys and Audi's electric A2 concept. This newest flight of fancy uses a laser diode as the rear fog lamp, which projects a red triangle onto the road to let other drivers know you're there. The German car-maker has tricked out the rest of the EV's lighting system as well by implementing matrix beam technology using LEDs and microreflectors -- giving it high resolution, non-glaring beams and intelligent tail lights that change in intensity based on weather conditions. Claiming other state-of-the-art features like gesture controls instead of keys, and brake lights that glow brighter the harder you press, it sounds like this would be a pretty sweet ride -- if it ever makes it to market.
