Ok , so I'am at the 'Trolley War' part after you split up with Khan and meet those 2 guys that want to take you to Miller. At some point in this mission I get to a crossing or w/e it's called and i just get blown up EVERY TIME , it's impossible to pass it i tried every option in the trainer , I also tried without the trainer , nothing changes ,I,ve been stuck there for almost 2 weeks now and I'm REALLY close to just chucking it in the bin.
