Most car companies now have a new measure of how good their vehicle is. It's not just the power of the engine or the speed it can reach or the acceleration. It's the number and size of screens in the vehicle, with an emphasis on the quantity of information that can be shown.

There's the dials and information screen in front of the driver, the centre console with the infotainment system and, if you are lucky, the heads up display.

But is it a matter of how much information, or perhaps how effective the necessary information in communicated.
