Been just playing around in cities puting on a show for people when im about to log for the night and I was doing lots of random movement (straffing/turning/running around) getting used to how I can turn them all at once and what direction they would be facing. Ive gotten rather good at it too atleast in general practice. The key is the starting point, all chars must be facing the same way at the start or you will end up with the boat problem keyclone mentioned, they will eventually get WAY out of whack if you are not paying attention and it is often only 1 or 2 of them.
