Mutro Botha is voiced by Tim Curry, the producers' original choice to voice the Joker on Batman: The Animated Series.
While riding in the Batmobile, Max complains about the lack of room and that, for all his wealth, Bruce could at least afford a back seat. In the original Batman: The Animated Series (1992) and its continuation The New Batman Adventures (1997), the Batmobile actually did have a back seat, since Bruce frequently had the backup of Robin or Batgirl. As Dick, Tim, and Barbara grew up and moved on, he likely removed it since its function was essentially lost.
