I have very similar feelings in moving from my Tesla Model S to my Macan Turbo.
The other thing I would add is it actually feels wonderful to press on a brake pedal and actually feel like the car has brakes that work!! The brakes in the Tesla were absolute garbage and you always wondered...
I think once the dealerships figure it out, it’s smooth sailing. Mine was one of the first two cars to arrive so it was the Guinea pig in figuring out how to get and install the update without it crashing. I would think the rest that are waiting will be easy peasy. Fingers crossed for you.
