Vehicles could work, the problem is implementation. Hopefully Bethesda won't use the Gamebryo engine from Skyrim (And yes, it IS little more than a slightly modded Gamebryo.) and that'd berid us of one problem. The problem also is in the current design, Fallout is big because we can only run so fast, but with a car, it reduces a 10 minute run to a 2 minute drive. If given the proper time, I'd love to see a vehicle in the game to use, provided it made sense and its fuel source was REAL rare. (Maybe it runs on petrol, and you have to tap whats left from certain old cars or petrol stations.) I like the idea of if you own a car, its upkeep would be VERY expensive, soley to add that 'Post-Apocalyptic' feel whiny 15 year olds say Fallout is missing now.
The thing that I'm against is adding an entirely new and complex feature that will take development time away from the more important things of the game.
Again this is an assumption and is based on what you feel are more important, altho I think I agree with what you feel might be important.
We dont know if adding x will make y and z have less.
vehicles have already been implemented into the series.
anyway, vehicles are neccessary, and it's fairly easy to make them not screw up the story. simply make vehicles consume more fuel and take some engine damage when not driving on roads, when your vehicle takes too much engine damage it dosen't run anymore and has to be repaired, however repairs would be hard as you would need a high repair skill and a few expensive exchange parts. vehicles should also not be terribly fast, infact they should only travel 60 to 80% faster than the player would on foot (and much less if the vehicle is heavily armored)

Me personally I want them added 1 of 2 ways.
Nothing more than a gimmick to start as another way to fast travel. Only this way if in dlc or future content transportation becomes more important.
A feature tied to your character and your progression as a mobile base of operations. This means scrounging and repair is more that just you and your gear but also you base. This means any movement will be barely above walking speed or even lower.
I am not asking for gta, or some sort of fast paced twisted metal combat.
Just something that seems intriguing to me to add to the franchise.
