I won’t argue with your lived experience but this would make you an extreme outlier.

About 20 years ago, every teenager in the world who had a mobile phone was able to select a contact from their phonebook and type an entire message and send, in class with their phone in their pocket.

This is possible because of physical buttons and a deterministic user interface. The same applies to cars and other control interfaces.

As I said I have two cars from two manufacturers. They have wildly different button layouts. Your example is a teen ager with a "single phone". In my case I have to resist the urge to read the tiny text on the physical button to know what I need to do. I avoid spending enough time in my car to learn the physical layout.

Simply having two cars they switch between regularly makes them an extreme outlier.
