I'd like to see a car with a laptop computer instead of an instrument console. The computer would run Linux (so it wouldn't crash) and you could open up windows on the screen for speedometer, gasoline usage rates, operating temp, oil pressure, all the usual. Since a computer, you could monitor many more things in windows which could be minimized or maximized, such as trip calculator, GPS mapping, etc. Controlled with videogame type cursor pads/buttons on the steering wheel.
