I guess the 3 doesn't have cabin overheat protection (or was that something that was there, but got removed?)
Outside temps in the mid-80s so nothing crazy yet. I do have 3M Crystalline 70 all the way around except my windshield.
I hope we get overheat protection - I was really spoiled by that on my S. I don't have good cell service at work, so turning on climate with the app was always dicey. But 105 max temp was much more manageable than 120 or higher with a black interior and a glass roof.
I would spring for the Model 3 roof sunshade, but it looks like they are out of stock. Ah well.
