Gotham, apparently, is safe at the moment. I know this because Batman is in Japan. He was seen speeding along a main highway in Chiba Prefecture (part of Greater Tokyo).
Replete in costume, cape and Batcycle, Batman was filmed by motorists in another car, who doubtless wondered if they needed to worry about some super-villain threatening Tokyo. I mean, jeez...if Batman is headed someplace at high speed, you have to wonder...right?
According to The Daily Telegraph:
...there have been various other sightings and photos posted online of Japan's caped crusader.
Chiba residents have dubbed their suburban superhero 'Chibatman'.
Unlike Christian Bale's Batman, 'Chibatman' seems to have no pressing mission to save the world as he has been pictured patiently waiting in traffic jams and following the rules of the road.
I guess that Batman is on vacation. I think he's earned it, don't you?
