This week on The Best of Car Talk, the auto-confessional is open, as a former road crew worker explains how he made sure he'd always have a supply of potholes to repair every Spring; and Seminarian Matt seeks absolution for letting his Trooper leak oil all over his environmentalist landlord's driveway. Elsewhere, Tom and Ray try a new strategy for difficult calls. Will "do whatever you want" work any better than "we have no idea what's going on?" Also, Marlene's Montreal-Boston drive has become non-stop, because if she takes a break her car won't re-start; and could Debbie's black smoke have anything to do with the rag that was wrapped around her air filter? All this and more, this week on The Best of Car Talk.
