INSTRUCTOR: The best way to figure out how suitable your engine is for cooking is to drive around for about a half hour-- then pull over, open the hood, and carefully check for heat. Quickly touch the metal parts of your car to see where the heat is. Plastic parts won't get hot enough, so don't worry about those. Unfortunately, if you have one of those fancy futuristic cars in which the whole thing is covered in plastic, you're just going to have to borrow your friend's car to cook on.
