This is a practice I've done since driving some old cars or cars with lots of miles because they always felt rough to drive when cold.
Also, I need time for the seat to heat up and the steering wheel to get warm. Takes at least 2 minutes.

+1 on the seals and gaskets. Those are the parts that suffer most in the cold and need time to warm up. I don't think idling for more than a minute or two helps any. I think driving the car as soon as possible after starting helps the most, but then the trick is to drive her nice and slow, like she were a Prius. At least for a few minutes, depending on how cold it is.
