Apparently, FICLY is eating my notifications, because I unfortunately missed this.

YU-443 makes me think of an old Buick, though those would be 442.

Maybe YU-443 was manufactured by the descendant of GM’s Autonomous Vehicles division—it doesn’t exist now (at least, I don’t think it does), but maybe in the future, and the Biots absorbed it, and produced our droid here.
