This week on Car Talk, what could make a seemingly mild-mannered '83 Porsche start rolling uphill, towards a nearby cliff, with its engine off? Poltergeists? Something in the water of its home-town, Radium Springs, New Mexico? Find out if Tom and Ray can come up with an answer that'll help its owner take it off the auto-suicide watch list. Remember our old favorite, Foreign Accent Syndrome? This week, we discuss a new entry to the world of odd neurological incidents: Foreign Language Syndrome. Hear what happens when one Czech motorcyclist takes a hit to the ol' noggin. Speaking of unusual brain activity, our hosts decide to take on the roles of schoolmarms, giving two callers homework assignments. Later, hear them share findings-- if only to report on "number of fingers lost." And, is a road-trip from West Palm Beach to New York City really the best time to learn how to drive stick? Sure, if it's not your car! All that, plus a new Puzzler from Ray's "Shipping and Handling" series, and lots more, on this week's Car Talk.
