have had my x for a few days. I assumed that I would be blasting the ac all summer because that's what I do with my ice car. we have had many sunny days in a row of around 100 degrees and I have only had the fan on about half way and I have been very comfortable. why is the model x the closest car I have ever owned by a long shot? are all electric cars this way? how can this be possible for a car without the sunshade with a gigantic windshield to be that cold in the summer?
