>The great thing about the touch screen is ... the flexibility when it comes to updates that also include new features
That's the main problem. Change is good only if it's optional, by choice. Forced redesign only makes designers happy, because they can now stop looking at that old version that they released some years ago and want to sunset it.
If you look at the 2012 Tesla dashboard, you'll see that it's influenced by really aged design patterns, it's good that they iterate on the UI as long as it's kept in check and doesn't become a Windows 7 to Windows 8 fiasco.
