2. Vehicles
This is one thing that people have been begging for. There are literally tons of vehicles in the various wastelands that should be operational by now. Now, Bethesda means to tell me that in the 200 years since the Great War, no one has taken it upon themselves to fix a car instead of walking everywhere? I just don't buy it. Fallout 4 needs to have a quest line devoted to repairing a car and then being able to race and drive it almost everywhere. This would lengthen the game by not putting in more fetch quests, and would be a sight for sore eyes in the irradiated wastes of Fallout 4, the reason being that the fast travel system is too cumbersome to use everywhere. Vehicles would be a very welcome addition to Fallout 4 according to the many forums dedicated to the game's development.
