You've never seen someone drive two vehicles at once?  Its astounding!

I know the Duramax has a larger displacement, but I thought the
Duramax would have less fuel usage at idle because its a diesel & the
Vortec is a gas engine.  The Duramax does get nearly twice the
miles/gallon that the Vortec does under similar conditions when being
driven.
