From the January 2008 (16.01)Wired Magazine; Artifacts from the Future, by Chris Baker. This future automobile HUD has some really cool features like a DUI driver identified ahead, in-car video chat, live GPS map with directions and a coupon for the Starbucks at the next exit. He's doing 90MPH, eating an energy bar and he's in the slow lane! For California, there definitely aren't enough cars on the road!
Looks a lot like a bunch of widgets on the desktop of your PC. It definitely seems too cluttered, but I think it was necessary to fit it on a narrow magazine page. I love that it seems to use a multiple-blink interface. Check out the calendar appointment in the top left: "...blink 3 times to reschedule."
If only this future were closer. I'm a real fan of car HUD interfaces. It's one of those promised technologies that still haven't become reality.
