When would you start cutting the ropes?
I'd start hacking away the moment I got to the other side. I don't care if others die, I've got to look out for number one!
I'd wait until the first of the zombies reached the far side of the bridge. That way I'd let as many others across as possible, but once the zombies step on the bridge it's time to weild the machete even if there are others still on the bridge because leaving it any later would be too risky.
I'd wait untl the last person stepped off the bridge before cutting the ropes. I'll just have to hope I can get through them in time because by then the zombies will be just moments away.
