If you're going to have the car for 10+ years, why in the world would it be a problem to learn the system in it?

The average ownership length for a car is roughly 6 years. Taking the time to learn a system that you'll have for anywhere from 3-6 years is completely reasonable.
This is the very definition of #firstworldproblems.
You certainly can learn the lousy interface in your car and there is some value in that, but it isn't hard to understand why the sales & marketing team is emphasizing that you don't have to (whether or not true in practice).
