Borrowing from the 2 cockpit idea found in the original Batman movie which was based on a Lincoln show car, Tant has used the biomorphic form vocabulary found in the Batman costume and in Bats themselves. The smaller cockpit accommodates Robin. I sent photos of the project to Tim Burton who was then the director of the Batman series of films suggesting he might develop it  for a future Batman movie, unfortunately he chose to go with a very Brutalist design which I felt didn’t capture the spirit of the character as well as Tant’s design does.
