In this week’s encore show: have mallet, will travel – Diana’s Volvo needs a little “encouragement” to get its act in gear. And Dave’s got a dilemma – no one wants tips from a backseat hitchhiker, but how much bad driving can a passenger stand? Plus, one more reason to leave your cell phone at home when you get into your car, as Pradeep learns a lesson the hard way. Also, a special holiday fable about a Fiat with magic gas mileage, and a listener takes Ray to task. That, and more, in this hour of Car Talk.
