Some of the most interesting times to be on TMC are when significant software updates occur. They reveal a lot about individual personalities and use cases that some of us wouldn't have ever considered. And about members' tolerance for change.
In terms of tolerance for change there is very little to compare it to because a car isn't really like anything else.
A lot about a car is muscle memory, and when you've had a car for a bit of time you get used to how you have it setup. It's probably why Tesla loaners are so popular. it's not just that it's an EV, but that it operates just like we're used to. In fact it's part of the argument for this new UI as it unifies the S/X/3.
Right now that unification has positives (like the triple view possibility), and drawbacks (no way to remove the nav screen, and inflexibility in what goes on top).
From a technical perspective I don't think there is anything preventing nav from being selectable. In fact one of Elon's many promises was to have a feature that allowed you to turn off the center screen or parts of the screen you didn't want.
I remember that promise simply because that's the one I wanted the most.
My take on this whole discussion is we have a lot of creative people, and it's a user base of people who drive the various cars (X, S, 3). So I'm not sure why so much focus has been on agree/disagree, and taking sides versus trying to push Tesla to something better than it is right now.
I don't think Tesla introduced this UI as being something set in stone. I'm sure they expected customer feedback.
I'm highly against the OP's tendency to disagree with everyone critical of the new UI. I don't think Tesla is even okay with criticizing people for expressing what they feel about the new UI.
Tesla has to balance two sides with a UI.
We all understand that Tesla has to innovate, and to line up the UI with what's coming down the pipe.
But, Tesla also has to be careful about alienating their existing long term customer base. Obviously if you own a product that does some function you don't want that function taken away.
The major SW changes do tend to be the the most interesting time to be on TMC. But, those that are the most resistant to change are those that have to give up something for getting hardly anything. The people prior to AP2 don't get a whole lot with this update.
It's easy to accept change when it's beneficial to you.
