It's not about knowing how many spark plugs are in their car. It's more about buying a car that comes with a custom power adapter plugged into the cigarette lighter, never realizing that you can plug your own accessories into the cigarette lighter instead of buying your phone charger or GPS from the car company, and then not caring when they just take away the cigarette lighter and replace it with their own custom port.

Since we know all analogies breakdown under close inspection, I'm pushing the idea that the best analogy is actually a brief description of the event / idea itself.

So in this case:

Not display www. in the address bar is actually a whole lot like not display www. in the address bar.

And if anyone doesn't understand why that is a bad idea, maybe we should explain it to them, which might require using admittedly imperfect analogies that they can nonetheless understand.
