This is becoming more prevalent in many states. The legislature will pass laws saying things like "at least n% or m questions on the new drivers test must have questions regarding X" for some politically motivated reason (some constituents child was killed by a drunk driver, drag racer, etc. Us bicyclists managed to get a question on the test regarding motorist/cyclist interaction. It goes on from there). Eventually you get to the point where this is the majority of the questions.
