What you just described is "Dark Knight" movie Batman. For decades, there have been different Batmobiles used, some flashier and fancier than others. While I don't want the Schumacher version, I also don't want the Nolan version to return (and I don't hate or even dislike the Tumbler. I actually thought it was quite badass. I just want to see something different this time around).
I guess it really all depends on the tone and look of the movie. Burton's Batmobile would've looked out of place in Nolan's movies, and Nolan's would've looked out of place in Burton's. Since I think we are going to get a more "superhero" Batman this time around, I hope we get a matching Batmobile.
Not just the Dark Knight. There are several versions that makes the Batmobile look powerfull and durable, yet maneuverable and responsive.
This one makes a neat example:
That iteration feels bulkier than Burton's batmobile, yet slimmer and more aerodinamic than the TUMBLER or the Bat-Riot-Control-Mobile from Frank Miller's universe. I can imagine Batman will use the RiotControlMobile in a urban warfare situation; such as TDKR (Miller), TDKR (Nolan), etc...
Batman must instill fear and have presence in the streets, and an agressive-looking armored car seems cut the deal.
Probably the least flashy Batmobile ever was the black Corvette of the O'Neill/Adams days in the 70s. Even that had a silhouette of Batman's head on the hood. I don't count the red roaster that Batman drove in the 40s as a Batmobile. The original bat motifed vehicle was the ornithopter. In the 40s. A more comic book/superhero Batman, of the sort that would not be out of place in the same universe with Superman and Green Lantern, is definitely about aesthetics. He combines his bat theme with functionality.
Yes, but Batman's theme is fear. And several light-hearted versions of Batman AND the Batmobile have nothing to really do with the atmosphere.
Batman is a dark, serious and gritty character, and trying to set him in a world of childish logic and over-used fantasy doesn't make any sense in my opinion.
Writers have been incapable over the years to come up with good impressive stories to follow in a coherent cannon and stable universe (with a few exceptions, of course). But it happens in a wide range of comics, were they exceed their power as writers and creators of a new piece for the "puzzle", in each story to their use. Bending the "rules" set in each world. Characters, gadgets, powers, scenes, etc...
