Yes, I agree. By having it switch to the night mode from Satellite mode, it improves your night vision. In total darkness it takes approx. 20 minutes for your eyes to adjust fully to seeing in the dark. The more light that is present, the less effective your ayes will be at seeing in the dark as they cannot fully adapt.
This is why most night time lamps for astronomy, as well as lights on ships etc. use red colored lamps at night, because red wavelengths affect our night vision the least. Instead of making the entire screen appear in red, however, Tesla decided to do the next best thing which is to greatly reduce the brightness--and to do so, uses the new night mode, which helps improve driver visibility.
