Some cars have HUDs right now.  Pontiac Bonneville comes to mind.  It has 
some sort of display (vacuum fluorescent?) embedded flat in the top of the 
dash, so that it reflects off the windshield and you can see it.  It might 
be hard to mount a laptop LCD in the appropriate place with the raked 
windshields that most cars have.

HUD=heads up display
