Okay since we all know there was a mass shortage of petroleum in the Fallout universe by the later half of the 21st century; that's to say that cars after the Great War would've been useless since there's no gas or oil. But, with the Brotherhood of Steel becoming a major research and development powerhouse after the fall of the Master and the NCR expanding and becoming the largest post-war American government. Do you think there would've ever been a chance that either the NCR or the Brotherhood would've researched into how to get those ghostly automobiles running and functioning again? Better yet, research alternate means into powering them so that way they wouldn't have to rely on pack brahmin to travel to say- between The Hub and The Strip? I would like to think that they would've done such a thing. I mean if Fallout went in some areas of development as with our timeline with alternative fuel usage such as solar power, biodegradable fuels, and even electric powered vehicles; I would like to think it would've been done and the NCR would've been way more stronger and everyone could avoid more dangerous routes on backroads that would be too fast for raiders to stop. I mean if the Chosen One in Fallout 2 was able to use Fusion power cells to have a car running again, I would've thought maybe the Brotherhood or NCR saw the use and used mass production to make automobiles available to the average citizen. And the NCR would've had way strength and would've been able to quickly reinforce troop movements between the NCR and the Mojave with motor vehicles. Especially in the area power is concerned, they would've had the means to make and likely power Tanks, battle vehicles, APCs', Jeeps, a whole lot on their hands. So, do you think that any of the powers put thought into developing motor vehicles after the war?
