How would one design & test this? How would one sanely design alien or futurstic looking vehicles?

It's very cool, nonetheless, but imagine if there had to be 2 people riding this thing, part of the gameplay, and now the truck looks so damaged, that placing these two characters inside would produce even bigger mess.

So what you do - you disable the truck collision for this case? You place the characters anyways?

Or just deal with a progression break, in now what would be much difficult ways...
