Lucy learns to drive — then teaches Ethel everything she knows. The crash course begins as Ricky buys a brand new convertible for their California trip. Lucy wants to learn to drive it and Ricky reluctantly agrees to teach her. And with that experience under her belt (she can't really be blamed for that U-turn in the Holland Tunnel, can she?), she sets out to teach Ethel to drive. It's a good thing the car's insured. It is insured, isn't it?
