I haven't forgotten about this but I've been too busy the last few days to add much to it. I did add something of an intro after it was moved to it's own thread, an in preparation for explaining the CDV I carefully dismantle mine the other day and took pictures of it. Just like the whole clutch system, it wasn't at all how I had imagined it in my head and I spent a lot of time wondering in my head why they made it the way they did. Then, all of a sudden, it was like a light bulb going off in my head and I am now completely convinced that I know why they put it there and what it is supposed to accomplish. It's not a safety feature at all, it's there to reduce driver fatigue.
