This week on Car Talk, a new entry to the Hall of Wacko Auto-Anthropological Research, courtesy of Beth in Oregon. Beth believes that women, and only women, become less attractive after driving for three hours. Can Tom and Ray offer an explanation, or is this one for Paul Murkey, of Car Talk's Murkey Research team? Elsewhere, Paula's Bronco seems to be whistling with perfect pitch; Jonathan's Saturn is laying out a smoke screen worthy of an Army tank; and former Bostonian Tim is finding the driving style in Vermont to be a little too polite. Also, a brilliant wiring job turned Helen's VW bus into a home. Sadly, it also may have made climbing hills an impossible dream. All this and lots more, this week on Car Talk.
