As Autoevolution writes, the Batmobile is formally not abandoned, as it has an owner. However, in fact, it is not cared for or maintained, which is confirmed by a thick layer of dirt on the body (although, according to rumors, the car is sometimes taken for a ride).
In total, there are 5 identical Batmobiles that were built for the trilogy starring Christopher Bale (Batman Begins, The Dark Knight, The Dark Knight Rises). Each of them cost 1 million dollars. Under the hood of such Batmobiles is a 5.7-liter V8 from Chevrolet Corvette with over 500 horsepower, and a characteristic feature of these cars was that they had the right to drive on public roads (legalized).
Most likely, the Batmobile found in the Emirates is also a specimen that was shown at a local exhibition back in 2015 and then put up for sale. Why the fate of this rare car turned out this way is unknown.
