Janet lives in a small town, and people stop to talk to each other. Is it better for her car to let it idle? OR should she shut it off? Tom and Ray say it depends on the age of the car. If it's old enough to have a carburetor, it's better to shut it off after about five minutes of idling. Modern cars are fine to keep running.
