 While filming in Lower Wacker Drive, in Chicago, Illinois, the  filmmakers were so concerned for the care of the Batmobile, that  they told the stunt driver to take as much time as he needed to make  any move. Therefore, when it came time to back the Batmobile up,  they went so slow as to cause traffic jams that had to be reported  on the news. Simply moving the Batmobile around Chicago took  numerous police as well as caused traffic jams where ever they went.
