This question asks if Batman could be arrested for driving an unregistered vehicle, in the real world. The answer, of course, being a clear yes.
In the comics, Batman commits several infractions on a daily basis, some of which that come to mind are over-speeding, damage to public property, driving an unlicensed/unregistered vehicle etc.
So, has the Gotham City Police Department ever issued Batman a ticket for his infractions?
