The Fallout universe is full of cars, which sit abandoned on the roads taking up space, and which are useful as cover from gunfire but for very little else. Fallout 4 needs to change this, and make vehicles an essential part of gameplay the same way Arkham Knight has already adopted. Fallout 2 had a drivable vehicle called The Highwayman, and Fallout 4 needs to retread the steps of its predecessor, because a vehicle would reduce the need for fast travelling all over the map, and would allow some completely original game mechanics. The vehicle could be used as a pack, carrying your most important items, a weapon to help battle enemies, as well as most obviously as a form of transport. Allowing users to upgrade and customise their vehicle to suit their purpose would make the vehicles seem important, not just a bolt-on addition. Skyrim had horses in their game, and it would be a shame if something similar was missed from the new Fallout game.
