So I was thinking about the display positioning, especially if you need to touch to use it (instead of the wheels on wheel).
Earlier in my car, if I needed to use phone for something (set navigation etc.), I'd always take it from my hands-free holder (which keeps the phone pretty much same spot as M3 display is at). When using, I'd keep the phone about middle of the steering wheel, so I can still mostly look at the road, and glance at phone when I feel it's safe to do. (yes, I know, don't use phone while driving). However, doing that I pretty much always felt I can keep enough attention to the road that it didn't increase accident risk that much. (yes, some amount for sure)
Now with the new hands-free law in WA, I've minimized the phone usage while driving, and in addition I don't take it out from the holder. But the times I had to use the phone (e.g. change my navigation destination), it was much more cumbersome and I felt much more prone to accidents. First I need to gaze totally different direction/angle than if I'm looking at the road, so I keep switching back and forth when earlier it was almost like just changing focus point while looking at same direction. And to make it worse, I need to slightly lean over towards to the phone to be able to reach it, making it even more difficult to keep straight line with the other hand.
So with M3, I'm wondering how much the screen usage will distract from driving. I'm sure most people learn the screen buttons easy enough that it doesn't really distract, but the cell phone experience for me made me think that the screen position might not be optimal for that reason.
