Batmobile looks like a frickin tank! Love it. Btw I donno why some people are freaking out over the machine guns. People are automatically assuming he's gonna kill people. It could just be there so that he could blast his way through obstacles.
Rubber bullets. More people who haven't already really need to read The Dark Knight Returns. That Batmobile literally iS a tank. Plus, the gun could be used for, other things.
