Let's say I've developed an laptop that bricks whenever you open a website with incorrectly formatted HTML.
Not sure how to adapt your bike analogy to this... Let's say you made a bike that's intended to be ridden outdoors, but breaks down whenever user sits on indoors. Yea, no one is supposed to ride it indoors. Not sure it's the best analogy though.
UPDATE: let's say the bike breaks down completely whenever it's ridden in the rain.
