This week on Car Talk, Tom and Ray discuss the ever-so-important car accessories: butt coolers and heaters! Cupholders and fuzzy dice are so passé--keeping your derriere at the optimum temperature is now what it takes to be au courant. At least, if you're Ray Magliozzi. Then, we delve into other pressing automotive issues... like how often should you clean bird poop off your car? And when it comes to breaking in a new vehicle, do you have to drive like a blue-haired old lady? And, when you leave a gas station with the pump nozzle in your gas tank, can you sue for emotional damage? Tom and Ray consider these slightly automotive but highly pressing ethical questions, and lots more, this week on Car Talk.
