Readily available? No. But if I wanted to draw a car, I'm iterating through parts in that way. And the accuracy of our "mental description" is certainly in question. Similar to how folks who can "picture a bicycle" can picture it incorrectly.

My wife and I have very different navigation skills. She can almost always tell me the compass direction and she's very good at relative directions. If she's in the house, she can instantly point in the correct direction of our children's school. I've got to stop and think through the steps I'd take to get there. I have to "reason" it out and she can just "see" it. It's almost like she's looking at a map of places and I'm dealing with a graph of nodes. I can walk the graph and understand how places are connected. But I can't really step back and see the bigger picture like she can. And I've got a lot of gaps in my graph because I only add nodes when needed. I could drive by a church a hundred times and not be able to tell you it exists. But when my daughter has a girl scouts meetings there, the graph gets updated.
