Double cltching is rather difficult in the crossfire anyway as the electronic throttle does not give one a precise instant throttle response.
That said, I double clutch when downshifting thereby putting less strain on the engine and clutch assy. Did a lot of that at the Dragon last week end.
I was driving another Crossfire last Friday on the Dragon with poor synchros. I could hardly downshift to second without double clutching. My experience with old 30's Fords and LaFrance fire engines came in handy.
And I too wonder the point, purpose, and origin of the rant.
