Absolutely not. Especially not in this engine.
This. FO3 had mods for vehicles, and it was pretty clear that the engine simply isn't set up to support vehicles.
Fallout 2 had vehicles. Can't remember if the rest had it. So it will only be a matter of time. Game makers aren't dumb enough to throw everything in the book on the first few games especially when they have a good series on hand. Features like these throw off bad reviewers/slaggers who go quickly go off the handle by generalizing about certain gameplay being identical to its predecessor.
Fallout 2 had a car which was only useful for fast travel on the world map. Fallout: Tactics had vehicles, but Tactics had maps designed for them and an engine optimized for them in the beginning. And it used sprites, rather than 3d. And it was top down/isometric, not first person.
