OOP is conducive to premature optimizations. It hints for you to find the right abstraction for future problems, because that's where the productivity gain supposedly is. Instead of rebuilding cars from scratch every time (in the future), I have an interface. Learning it starts to train you to look for these opportunities, and eventually you start thinking "what if this class becomes a foundational class? I want everyone working on it to have a great time. I don't like being cursed out for not predicting the obvious future", and so now there's a bunch of onion-y stuff added.
