Okay if I'm being honest here, I still don't get the Sphere, at all. I mean I understand the size and I understand the shape, but the inside? It's a mystery to me. Even after the whole discussion, even after rereading descriptions of it that have come up in people's posts and tags. So mostly I've just been winging it, which is fine for me, but like when I get around to actually doing a write up trying to describe the Sphere for the game info I'm totally screwed.
It's such a relief to admit my ignorance.
All that said, yeah, sure, cars sound good. Though I'd expect they'd be like electric or "solar" powered or something?
