Transparent windshields would display widgets

To build on my last post, imagine that the windshield in your car is like your computer desktop. Your desktop can display yahoo widgets or apple widgets to show you a calendar, clocks, rss feeds, etc.

Move this idea to your car windshield so you can see texts, maps, traffic updates, etc while you're driving. Of course, it would not obstruct your view but be displayed off to the side for brief glances.

It's a dangerous idea if implemented incorrectly, but I think it could be very helpful.
