I have the opposite problem. My primary DD is an F150, which has the radio controls on the right. When I get in the Fiesta, which my wife DDs, I always get mixed up between radio and cruise. To me it seems more logical to use my right hand for controlling the radio, and it's the hand that has done it since I got my license some 45 years ago. For that matter, cruise control was always controlled at the end of the turn signal stalk in the old days, so left hand for cruise seems normal too.
