Last time I checked , it was still Darwin Theory of Evolution . Really ? Really ! On this forum ? ?!! A scientific theory is a wellsubstantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed , preferably using a written , predefined , protocol of observations and experiments . WikipediaNOT the same as theory in everyday parlance . Maybe try this angle on rChristianCreationists <| sep |> Thanks for that valuable contribution . <| sep |> Sssssh the NCR is a democratic republic . It doesn ' t have nobles it simply has wealthy businesspeople who , by sheer coincidence , happen to have a lot of influence in society and politics . That aside from Fallout Bibles 5 and 6 . About how many working or servicable cars are there at the time of FO 2 ? Obviously there must be more then one , since the guy in new reno has a garage fully staffed , and most likely has a large supply of partsProbably not too many , but I don ' t know the exact number . The real problem isn ' t fuel , it ' s mostly tires and other degradable parts that have gone to the dogs in the past 100 years . For every two hundred or so people , there might be one working vehicle , and even the local clunker wouldn ' t be up to factory specs . NCR is rumored to have a mechanized vehicle division outside of its farming vehicles , but the number of vehicles in the division is unknown . We see a lot of military trucks around NCR outposts in New Vegas , so presumably that ' s still working out for them . Last update , you said there were 1200 carspeople ration in the NCR . If there were so many working cars in NCR , where were they ? They ' re there . It ' s game logic . You don ' t see them for the same reason NCR is only three maps , only has 1 councilorsenator , and only about 4050 people in its city limits . That ' s why the Chop Shop in Reno exists , why the bum outside of NCR offers to watch a car for you before you show up in one , and a reason that NCR built a garage in Shady Sands . And before you get the image of tanks and jeeps flying around everywhere with heavy machine guns mounted on the back , most of that junk is old tractors and crap like taxis , old buses , snowplows , and even old construction equipment . It ' s possible that mysterious old steamtruck mentioned in the bowels of the F 1 data archive is still lumbering around somewhere . The caravan houses of the Hub , in particular , around the time in Fallout 2 , have been looking to further its trade influence , and new vehicles and types of transport , such as trains , boats , or barges have been eagerly sought after for carrying large amounts of trade goods vast distances . Good ol ' human greed will move mountains . Or at least rebuild things that can . Once they learn of the Enclave ' s presence in the North , they are likely to have huge bounties promised for vertibird plans or better , a working vertibird . Again , New Vegas shows us that they ' re indeed rebuilding the railways at least until the powder gangs rebelled , and even got hold of at least one vertibird . As MattTheFreeman notes , biofuel research is valuable all across the wastes even the Boomers out at Nellis have managed that plus whatever old fusion engines wasteland mechanics can get working . If we ever get a Fallout game in an engine that can handle ground vehicles , it ' s entirely possible we ' d see a few interesting examples trundling about .
