Something I came up with while watching some pictures of the Model S dashboard. When I'm driving at night I try to turn down the light in my car as much as possible, that makes visibility better. Something that is used in aviation (correct Lloyd?) is the highlighting of important data and disabling data which doesn't matter at that moment. I think Saab implemented this in their cars, they would only illuminate that part of the speedo where the needle is. Why light the whole speedo when just your speed is important. Why light up the oil/coolant temp when they are inside normal values? This way you take away unnecessary information input to the driver. I don't expect this to be in the Model S from launch, but since it's a computer rendered screen it would be possible to implement the same. This way you could have a minimalistic HUD with only displaying what you need, for example: Why show me my SoC when I have more range then my navigation destination is set to? What do you think?
