As promised, here's a look at a custom tumbler made by Rudy. Not me. I am not Rudy. I am not taking any kind of credit for this, these are just to share with you all. Though I think Silverdream has seen it.
You can see here (I hope) that there are two steering wheels and computers, and the batcycle launches somehow, but I didn't know how and didn't want to break it. Rudy wasn't there.
