maps kind of small for vehicles, and the terrain doesn't really suit them
No I feel vehicles would ruin Fallout personally
Vehicles fall into the multiplayer/ co-op area for me: I hope it never happens.
Maybe 1 working car? I don't know.
Maybe let you ride a bicycle?
And as a free update in a patch though. No selling of DLC's and instead sell expansion packs. I'm looking forward to Bethesda Game Studios selling at leas up to 3 expansion packs for Fallout 4.
