Mitsubishi's experimental Safe and Secure Lighting system takes turn signals to the next level. Instead of tiny blinking lights, it uses big road-surface projections coupled with car displays to inform pedestrians and other vehicles what you're going to do. When the car is in reverse, it projects big illuminated arrows pointing backwards. Ready to step out after parking? The rear glass shows a stop sign and the door projects a signal that clearly states you're going to open it. The best thing about it is that it automatically activates based on your actions. Unfortunately, the current version doesn't seem to have illuminated signals for right or left turns yet.
