>>9868455Can confirm the DC collectibles animated Batmobile will fit Hush Batman, but his cape will be uncomfortabe and you want to be careful with his ears for clearance. He'll have to recline back, but not super unnatural.
other options are the Mattel 66 Batmobile, and there's two 1/12 BvS/JL Batmoiles; one is an RC vehicle with the gun, unfortunately, the other is a premium collectable with the gun as an option.
