That likely involves chip architecture, ASIC stuff, etc.
. I have a Proclip mounted 7" Android tablet on my dash that works just fine. Most engineers prefer to work for $ and I doubt there is much to be gained financially from all this. If Subaru decided to enhance their info display it would make a lot more sense.
The WRX has a pretty extensive multi info display.

Programming the arduino is most similar to Java.
I built an Arduino datalogger for my vintage racecar.
It logs AFR, EGTs, CHTs, oil press, oil temp, fuel press, throttle position, Tach, and some spares.
It logs locally to a mem stick, and controls the shift light and the Dash Warning light.
It also sends the data over USB to a droid phone that I use as a data display for realtime data, and a graphing feature.
It saves the data to a logfile as well.
That system (with a CAN shield) would do exactly what you are talking about (and then some).
