every car is required to have a screen and no physical buttons with outdated shit software

That isn't a requirement, just companies chasing shitty trends. Several brands never dropped the physical air conditioning and volume controls from the dashboard or reversed it within a year or two based on feedback.

You are ranting about industry trends and conflating them with safety requirements. Those things are intertwined in some ways but the majority of your rant has nothing to do with actual requirements, just shitty cost cutting choices.
