The first application I’ve seen of an actual dash display for a car was with the REV:

MotoCzysz didn’t integrate the iPhone, Its to show what is possible with a completely digital bike and how far tech could push this new era of electric vehicles. Just think of everything you could do with it… as Neal said… Download maps.

A few other things:
- What about logging your “Amps and Volts” along a trip? You would then know how much power you use up hills and how much you regen down hills. Then you know how many Wh/Mile you use… and you can integrate this with 3-D map data and actually plot your most efficient route to your destination and back. This would be useful for gas vehicles, but moreso with Electric vehicles.
- You could have your car/bike/etc hooked to the iPhone and if you get stuck, it automatically calls the manufacturer and uploads the log data. It can help debug on the fly. They could even send a AAA truck with a buttload of batteries to “dumpcharge” your vehicle if its low.
- You can sync your car with your computer at home. Upload traffic data immediately and avoid long delays (although it doesn’t use much electricity if you’re at a stop ;) )
- You can have voice commands to set things into eco mode or sport mode, voice “security” to enable the car, voice commands to display battery level, state of charge, battery charge/discharge history, etc etc.

There’s a lot you can do with a little computer in a case. Plus you can take PDA’s and Iphones with you when you leave… even if someone DID steal it, they can’t Unlock the vehicle without it.
