This week on The Best of Car Talk, Amy's husband is no longer driving a stick shift but is still using both feet, keeping his left foot on the brake. Is this dangerous and can Tom and Ray help Amy find something else for him to do with that foot? Elsewhere, Esther is looking for a Get Out of Speeding Tickets Free card due to her car's stuck idle; Edabeth's Volvo sounds like an airplane readying for takeoff; and Nathan wants to take shade tree mechanic to a whole new level. He's camping out in a redwood tree to protest deforestation, and has noticed that one of the trucks passing by every day is running rough. Can he diagnose this from his leafy perch? All this and more, this week on The Best of Car Talk.
