It's happened to all of us. You're on a long drive, when nature takes its course and you find yourself desperately needing to "take a haircut." Finally, a restroom appears, but it's inside a fast-food restaurant. This week on Car Talk, we tackle the moral quandary--if you use this restroom, are you obligated to get fries with that? Elsewhere, Tom is worried whether his Nissan's shocks can handle an upcoming road trip. Click and Clack are more worried that Tom plans to make said road trip with his mother and his girlfriend. Also, Erica's goal of getting her Camry to 200,000 miles hits a noisy obstacle; a clay-gathering trip turns smoky for Charlie's Explorer; and Bill's attempt to replace a broken belt with a pair of tights failed. Did he use the wrong size? The wrong color? Find out, this week on Car Talk.
