I tend to do this almost instinctively, perhaps in an effort to minimize clutch and transmission wear. Not a full-on double-clutch maneuver, just a blip of the throttle whilst downshifting to get engine and transmission speeds closer together. Am I weird, or does anyone else do this?

(and now a gratuitous shot of a Mazda5 interior a little better equipped than mine, better than you can get in the US if you dare to be so weird as to want to shift for yourself)
