Some universes are parallel. I was in one that wasn't mine, but identical to it, and my family had been to a few others. But this one is different, it's nothing like any of them.

[ Jack is used to the universes mostly mirroring each other because that's what his grandfather did, he created the same thing and just tried to perfect it, or he left it to rot because he got bored. He still does think that Chuck exiled him here. It's just outside of his common space, maybe? Jack doesn't know, he's not an expert on any of that. ]

These are the gear shifts. This makes it go forward, backward, and also you change it when you want to go faster. It's kind of intuitive, when you start going things will feel more natural.

[ Jack adjusts the mirrors. ]

You want to be able to see behind you and the mirrors on the sides so you don't hit anyone. And there are the lights you put on, and the windshield wipers.

[ Jack does all the little buttons so she can see when they work and what they do. These are the details that she could probably come up with by poking at things on her own, but he's here so he might as well guide her. He wants to be a good teacher! He's never been one with all the knowledge before, it's fun, he could get used to this. ]

I don't know if they have speed limits here, but there may be signs you see that say how fast you're supposed to go.
