This isn't the place for a crash course in statistics, but from a modelling perspective it really shouldn't matter very much how many people are in each car. Any volatility in this number isn't going to differ markedly from that which is already observable in the historical series.
I think the most likely explanation is that they were able to predict this problem with a pretty good degree of accuracy, and chose to prioritise a financial decision over an operational one.
I think this is newsworthy and I hope it bites them gently in the rear.
