Hmm. Not sure the metaphor works for me. I see crash test dummies completely at the whim of the person who sticks them in the doomed vehicle with no choice in the matter, no ability to speak for themselves. A test dummy has no option to quit because he is mindless and completely powerless to do anything about his fate.

I've never felt powerless in my therapy. I've never felt at the whim of my therapist. They have always given me a voice and options on how to proceed.
