1.Gasoline: theres clearly an overabundance of gasoline since cans and barrels of it all over the place so why doesnt anyone use it in cars or motorcycles/dirtbikes to travel easier?
2. Virus: ok so the virus was supposedly spread worlwide by US money and tourists but this wouldnt exactly mean the virus has infected everywhere. like some countries would have no tourists at all or wouldnt handle US money or currency at all for that matter. I could see north korea declaring war on america and stuff like that but its never explained?
3. why does everyone want to kill eachother? im sure in times of crisis people would eventually want to make deals to end conflicts and return to peace so life can be easier/better and at the time of outbreak everyone was still part of their own country so they should have felt like allies instead of enemies...
