Oh yes, black ice is nasty. But I used to slow down during very cold mornings anyway and only slipped once in a remarkable fashion with rather slim tires. If you're slightly used to biking, you will have a foot down almost immediately (which will also slip, granted), but it almost always becomes a rather comical slip that takes you to the ground rather slowly instead of a neck-breaking action stunt in my experience. I guess it is different if you have full racing gear and a street racing bike, don't want to slip with that.
