This week on Car Talk, if one car drafts behind another to improve its gas mileage, does the car in front suffer? Tom and Ray's answer, or lack thereof, may bring the late Physics Professor Tisza back from the grave, just to administer a dope slap.
Meanwhile, dope slaps might also be in order for Jessica's mechanics, who will only discuss her car problems with her boyfriend, while ignoring her. Also, the solution to Nancy's Miata's hood problem may lie in her local tanning salon; Melanie is about to learn a very expensive lesson about what her oil pressure light means; and, one listener offers the real definition of "primitive" four-wheel drive. All this and more, this week on Car Talk. [Broadcast Date: January 18, 2014]
