This OLED windshield concept has some nice safety possibilities, like a more visible brake light and turn signals. But I want one so I can give a giant digital middle finger to the jerk tailing me.
The concept features both front and rear displays, and they're user-customizable so you could show support for your favorite local sports team (go Philadelphia Kixx!) or flash a big stop sign to augment your brake lights. But isn't this just asking for pranks?
It's still in the concept stage, although if a manufacturer picks it up, it could be ready for release in 2 or 3 years. Until then, I'll have to be satisfied with the old-fashioned analog method: the two middle fingers God gave me. [Wired]
