It's a small piece of useful information, though we mustn't the take the NPCs for granted. There are specific NPCs and objects that can be interacted in the game that explain things in more detail. It would be more effective to direct players to them. The list I've found are:
Mechanic (1 at the Mumford garage and 1 at a garage between Murphy and Zanesville) - Explains the basics garages and towing etc.
LifeNet Fast Travel Terminal (In every LifeNet Fast Travel pod) - Explains how to Fast Travel and other requirements.
Town Crier (In every conflict/defense town) - Explains the basics of a Conflict/Defense Town, and their statuses/progress.
Blood Sports Converser (Mostly in major towns) - A short history and basic tutorial on Blood Sports.
Construction Trainers (In Capital Towns) - A basic tutorial on the Construction tradeskill.
