This week on The Best of Car Talk, Joyce’s mild-mannered husband teaches meditation by day, but when he gets behind the wheel, he turns into a cross between Mario Andretti and Tony Soprano. Is it the car, the traffic, or does Joyce’s husband have a dark side? Elsewhere, Andrew is concerned about his washer fluid lacking testosterone; Catherine has lived five years with a buzzing oil pressure indicator; and Aaron’s Impala now takes off like it’s dragging a ton of bricks. Also, Jim is worried he may be a Fire Starter after his battery and muffle both exploded. All this and more, this week on The Best of Car Talk.
