Again, Space Marines should be cruising in it, nto Batman.
Weird... Oh well though, Batman's a lost property to me. Toys suck and so do his movies. Too bad he's not getting the same care Spidey did.
If the first half of the script I've read is any indication, Batman IS getting the Spidey treatment (minus the Power Rangers villain masquerading as Green Goblin).
The Tumbler WAS designed for Marines. I can go into specifics, but I might be going into spoiler territory. I know if I decided to become a millionaire vigilante and had this in my Applied Sciences Department, I wouldn't feel the need to overhaul a Lincoln with Batfins instead.
And keep in mind, those specs
are for the real-life vehicle, not its movie counterpart. While the wheels may not be bullet proof for practical filming purposes, I doubt the movie specs would allow for such an easy target. We'll just have to wait for the DK book to be sure.
