When guests get onto a ride, the first group in line gets on. If the next group in line has more people than there are available seats in that jeep/gondola/train/whatever, it leaves with a partial load. So sometimes, the ride leaves with two people, sometimes with five. It would be nice if the game had some sort of intelligent AI where instead of JUST looking at the next group in line, it would then go back to group 2, then group 3 to see if those groups would fit. To limit the amount of processing needed, it could cap after the third group instead of the first group. It would make shorter lines and the ride would run more efficiently. (Especially shuttles). Most theme parks do this already.
