Summary: <p>This week on Car Talk, Barry's holiday road trip through South Carolina got more exciting when his wife noticed the road behind them was on fire. Was it coincidence, or was Barry's truck an unwitting arsonist? Farther South, things are a little less exciting for Rick in Florida. His PT Cruiser's explosions are only taking place under the hood. Also, have you ever heard of a Himalayan Exhaust Transfusion? Neither have we, but it might be a great way to start a dead car on a cold day. Or, it could just be a wacko theory. And, our on-call Physics Professor Wolfgang checks in on the great drafting debate. All this and lots more, this week on Car Talk.</p>
