Not so long ago, kids were content just knowing that Santa was in the air. Eventually, NORAD got into the act, giving children and their anxious parents precise details of the big guy's whereabouts. Now, General Motors has joined the fray: this Christmas Eve, children of all ages can get updates on Santa's location from OnStar reps -- just press the OnStar button in your vehicle and ask for a Santa update. And that's not all: GM has given St. Nick a new ride, the Star Duster 5000, equipped with OnStar to help him navigate the snowy skies. No, it's not as bitchin' as the sleigh he just got from Land Rover, but at least this one won't send Rudolph to the unemployment line.
