This last week there weren't any cards or anything... they just start with pilot, then gunners and then engineers, single rider usually filled the engineer spot if there weren't enough in the group, or if there wasn't a group of 2... we were a group of 4 and always got the first 4 spots (well, my one daughter like engineer the best, so we took pilot and one gunner, one engineer and they filled the other spots with a group of two/single riders)
So if you have a bigger group you have a better chance to get what you want, as a group of two/single rider you'll get moved through faster as a fill in, but they didn't seem to care much about people trading spots in the earlier stages when you are just line up.
