I think the basic driving controls are improved. Use of bolder fonts for battery level, TACC speed etc and the new thinner font for the actual speed somehow makes it stand out as well. Moving the map compass to the right means it's far easier to reach as a driver. The power/regen bar is clearer, but it kind of defeats me as to what action I might take based on that. Having Spotify, Radio and Energy as my pinned apps definitely reduces the number of clicks, and I can slide them back out of the way more easily than before.
I guess time will tell how well the auto seat heaters work, I'm the type that set the temperature to 20 and auto when I collected the car and haven't changed it for over 2 years, so it's probably never going to be changed again.
