You're absolutely correct.
Most bus drivers couldn't tell you how a diesel engine works and they seem be able to drive busses quite safely.
And let's face it, airline pilots are becoming more like bus drivers every day. The sooner this is reflected in the theory syllabus and exams, the better. (OK, I know, the pilot's pay is often less than the bus drivers, but you get what I mean).
