And 4 years from now people will STILL be asking "How do I get a vehicle?" "I thought there was vehicles in New Vegas???" "I found a car how do I use it?"
Are you sure you're not looking up the Fallout Tactics skill list, which had pilot if I remember correctly.
Yep, Fallout Tactics is the only released Fallout-based computer game with that skill. Van Buren also had it, and it's in J.E. Sawyer's Fallout Role-Playing Game as well; Van Buren would have been called Fallout 3 if it had been released, and J.E. Sawyer's Fallout Role-Playing Game is a tabletop RPG rather than a computer game.
