Strange analogy I must say...hmm....is she open to blumpykins instead?
Lets say he's running a 4awg to two 8awgs. The 4awg will take up to a 135A fuse, and runs to two 8awg wires (rated at 65A). Lets say one of the 8awg wires has a soft short that does not exceed 135A draw to blow the main line but exceeds the 65A the line can handle. If you dont have an extinguisher, you will watch the car burn down. It's pretty rare, but it has happened. What's an extra $10 for insurance? As for the analogy, I thought it was pretty spot on. But chicks willing to do blumpkins are actually rarer than a car fire caused by bad wiring.
