Has to be said, he's being pretty sound considering pretty much everyone present is saying Superman would beat him in a fight. 

Here he surprises tourists in the new Batmobile during the Warner Brothers Studio Tour. He let's people touch his face, who don't quite believe it's him (I blame the hair...), invites children to sit on his knee, before thundering around the lot and bringing one quietly ecstatic dude for a spin.

Then he goes on to plug a competition for Omaze, in which you can "hang with Batman v Superman: Dawn of Justice’s three leading men at the film's premiere", while doing your bit for charity.
