Spend some time on Bimmerfest.com there are a ton of BMW enthusiasts and there are all sorts of ways you can hack into the cars' various electronic systems and change things. For example, mirrors fold in automatically when you lock the doors. Windows roll up and moon roof closes at push of a remote button, turning on cameras, feeding video to your GPS or HUD display (from your cameras or another sources), change the cluster display's colors, info, etc., and lots of other things. Mine already has a digital display (called the "sports" display) that shows most of what you're talking about. You can also put the vehicle in different modes (Eco, comfort +, comfort, sports, sports +, and M) that changes both the feel of the vehicle and the displays. For example, sport mode changes the HUD and cluster displays to digital readouts, in comfort and below they are analog displays (digital but the images are of a needle speedometer and tachometer, etc.). Of all the cards I've had this one is the funnest and most hackable.
