I was just watching that show earlier, incidentally. I think it's worth noting that the schoolbus is textually referred to as a train, and I think the droid driver is basically just there for charm.

I'd also like to say that I tend to view things like Skeleton Crew as basically just "fanfiction with a license", so I personally just thought "heh, Star Wars Eagleland, that's cute." while watching, without really caring about the wider implications for the Star Wars canon. But that's just how I tend to enjoy fictional "IPs" or "franchises", personally, by looking at them as basically just folkloric cycles whose status as such is obscured by copyright.
