CHICKS DIG THE CAR
Come on, who hasn't wanted to drive the Batmobile? The Batmobile is the ultimate car, the most badass thing on four wheels to ever grace the streets of Gotham. There isn't a kid alive who hasn't dreamed of waking up one morning and seeing that black shiny mass of awesome sitting in the driveway. That's why we won't stop banging on about it.
Now, Rocksteady's said it doesn't want to divert attention and resources away from other areas of the game to create drivable vehicles that could be a bit hit or miss, but we have every faith in the studio. They've nailed the combat, stealth and detective elements of Batman so far, now give us the keys to the car.
Scooting about wouldn't have worked in the tight confines of Arkham Asylum environment, granted. Even Arkham City is a bit too small and, well, messed up for the Batmobile to be used efficiently. Drop a Gotham City environment in our laps though and that might just work.
The only problem we can see is that something would have to be put in place to prevent players running over civilians. Batman's not down with that.
