Matters how many WILDCATS are in this set but this just made me pay attention to a Buttman set.

To me, even though some of the vehicles fly, I would have equated "Streets of " XXX with vehicles before any other set. But someone thought that it would make more sense to include them in a set called "Batman" because that makes more sense somehow.

It is not like there are more vehicles that fly relative to vehicles related to Batman that are being released.
