You have given the driver your destination and want to know whether he knows the best route – sometimes your phone knows more about the current traffic jams, but usually the driver does: Do you know the quickest way?
He drops into a fighting stance, puts on a judo belt and says he will if it is necessary (Do you know), then burrows into his chair (the), squeaks like a piglet and grabs a few branches to clean the windscreen (quickest), and drives around a pond (way).
