Coming from a Model S where without a heat rejecting tint, the a/c had to work overtime to keep up with trying (and failing) to keep the cabin cool. Once I had Spectra Photosync tinting done, it was a night a day difference in comfort. What I'm wondering is, given that most of the windows are already tinted on the Y, for those of you familiar with this situation have you found it necessary to get tinting done? I did do a test drive, but the car was pre-cooled so I can't tell if it was an issue.
