With this, I disagree strongly. I frequently change the volume on the radio, and adjust the supposed AutoClimate control on my current cars. Unless Elon has figured out a way for a Vulcan mind meld, I assume that I will do the same on the M3, (or at least I will try).
If the volume control is on the steering wheel, that will work.
Not sure how to control the temperature, however, without major distraction by playing with the tablet.
Like another poster on this thread. I too have a "moon" roof on my current sedan, and I think I have opened it twice in 10+ years. Thus, I could do without all an all-glass roofline. Plus, wouldn't a metal insert be more structurally sound?
btw: I'm all in, and will still exercise my Reservation. However, my wife will likely pass on Res #2.
