Be careful not to make too much of the usual bumps that you are bound to hit while traveling down a road you`re unfamiliar with. Just because the car jumps a little, that doesn`t mean the engine is failing or the map is wrong. You have enough knowledge of the fundamentals and a good enough sense of direction to get where you are going. If your passengers insist on putting up a fuss, perhaps you can calm them with a few reassuring words. You are about to arrive in grand style.
