This week on Car Talk, welcome to foliage season! Tourists are descending on New England, and locals like Kurt have plenty of time to sit in traffic, developing theories about the drivers clogging his roads. Hey, if wacko Auto-Sociological musings keep his blood pressure down, who are we to argue? Elsewhere, Angela's about to get some sour news about the sweet smell emanating from her dashboard; no good jump start goes unpunished for Bridget, after a friend accused her of doing $1,300 of damage by charging the battery backwards; and, is Ed really about to turn to electric shock therapy to keep his beloved cats from marking their territory on his cars? Also, on Stump the Chumps, we find out if Kate acted on her Matrix buyer's remorse. All this, plus a new Puzzler from the inky shadows of the World War II series, and lots more, this week on Car Talk.
