How hard is the transition? Do you ever forget what transmission you're driving? I alternate fairly irregularly between my 5-speed Civic and my automatic Buick and only once have I reached for a phantom gearstick or clutch (panic stop). Furthermore, I noticed that I automatically left-foot-brake in the Buick and right-foot in the Civic. Anyone else? Do you ever drive your manual and confuse the clutch and brake? Forget that you have to change gears and wonder why you're hitting fuel cutoff? Forget to go to neutral while coming to a stop and stall the engine?
I'm curious, oppo
