Yes, Project Reality has the ability to switch to "back-up" secondary sights if the rifle is equipped.
That would be helpful but I suppose the code would have to be borrowed, if they were willing.
My question is: Why does the German Kubelwagon accelerate so slowly from being stopped? It seems that it has no power.
I do not think the American Jeep is quite a sluggish, but it is somewhat similar. These vehicles could take off more briskly, realistically.
I seem to remember things being different in the past. Right now, you jump in, and you can't just take off. Perhaps that simulates starting the vehicle? The only problem is, once it is started, you should not have this problem anymore with subsequent stops and starts.
