In the original script and storyboards, The Batmobile was originally supposed to take a brutal beating coming out of the factory, even getting destroyed in one of the drafts. That's why Batman takes the Batwing.
I would have had a sad.
INT. ACE CHEMICAL - THAT MOMENT - NIGHT
The BATMOBILE cruises through the flaming wreckage and
SKIDS TO A HALT on the refinery floor. The JOKER'S MEN are
everywhere. They take one look at the BATMOBILE, PANIC, and
PELT THE CAR with a barrage of MACHINE-GUN FIRE.
CRACKS begin to spread across the Batmobile's plexiglass
dome. Within moments, the windshield SHATTERS -- and
COLLAPSES ALTOGETHER.
INT. BATMOBILE - THAT MOMENT
BULLETS rip through the upholstered passenger seats. It
doesn't matter. The car is empty. No one's driving.
TRACK IN on the computer console -- where a familiar tinny
voice calmly repeats its pre-programmed command:
COMPUTER
... Detonate.
A beat. Then: BLAM.
EXT. AXIS CHEMICAL - ANOTHER ANGLE
Debris and dust fall to earth. The building is devas-
tated. Flattened. Nothing could have lived through the
blast. A BEAT. SILENCE. Suddenly from within the
burned rubble -- A RUMBLE.
CLOSER - ON DEBRIS
Something stirs, lifts, moves up and then out, struggling slowly,
the Batmobile pulls itself out of the debris.
EXT. AXIS CHEMICAL - NIGHT
BATMOBILE drives up to the gate. From out of the dark-
ness Batman steps and pats it on the fender. It CHUGS.
