The act of steering with the knee, when you are far too busy to use your hands. I.E. Shuffling through maps, your CD's, applying your face, arm wrestling with your passenger, etc. Usually preceded by pressing the "Cruise Control" button.
Brenda and Tommy were far too busy playing Scrabble on their way to Montana. Good thing he knows how to knee-cruise.
