once again thanks for all the kind compliments.
brief answers to some questions:
you need an engine with enough torque to turn those 44" superswampers. Definately a V-8
thoughts on future Batsuits: I like the idea of segmented armour, because if there were to be a real batman, he would need ceramic armour protection, but be able to move, so realistically it makes sense. And from a film standpoint, what makes sense in the real world draws us into the film. i.e. a light grey pair of tights would make him a target, offer no protection. a bat emblem with a yellow background would make him a glowing target. Black makes sense. Even the change of voice makes sense, because Batman has to startle, intimidate. Seem almost monsterous.
Batpod makes sense, because it can manuver, wheras a full-size car cannot. But, a car can house a lot of arsenal that a bike cannot.
