This week on The Best of Car Talk, Jill’s pal keeps telling her she needs to do more highway driving to “blow the stuff” out of her car. Jill’s not opposed to this, but what exactly is she trying to blow out? Elsewhere, Eleanor is leaving on a six-month, around-the-world bicycle tour and she wants to know what to do with her truck while she’s gone. Tom and Ray want to know how Eleanor plans to pedal across a few oceans. Also, after Lauren’s boyfriend drove down Mount Washington with the emergency brake on, Lauren is wondering if she needs new brakes, and/or a new boyfriend. And, Rich’s broken gas gauge gives Tom and Ray a chance to fail Calculus, again! All this and lots more, this week on The Best of Car Talk.
