Parked: The car visualization seems like it's for showrooms. Otherwise it's an overdesigned way to open the frunk.
Reverse gear: Nobody's going to look at the car visualization. It should not take space away from the backup camera view. (Model 3)
Driving: I haven't found much value in the visualization and I'd much rather see more map (and a blind spot indicator in the side view mirrors). If the screen showed the side camera when the turn signal is on, that could help.
Safety warning indicators: They need to not be hidden behind a hand on the steering wheel! Is the gray "horn" symbol with an "x" trying to indicate I set the horn to no-sound? Why is that even allowed?
Clearly the text, indicators, and tap targets need to be larger, high contrast, and no thin-strokes.
Battery gauge: Make it larger. Show both battery % and estimated distance.
There should be a way to adjust the fan speed, temp, and wipers that requires as little eyes off the road as possible. Auto-wipers mostly work now but still.
Some things did get better, like the placement of the rear-view and wiper-panel buttons.
My bet: They were still debugging the next batch of changes but Elon promised a
holiday release so they rushed out the Santa glitz, some finished parts, and
in-progress untested UI changes.
I sure hope they
normally do enough usability testing to discover design details that people can't quickly read while driving on bumpy roads or that people have trouble understanding.
