I like that. You could carry it even further, in saying that you were say the fire chief commissioner and the two vehicles were fire trucks from two different companies, both of whom had heard you lecture time and time again about how important it was to maintain communication with each other and to keep the engines running smoothly . … and that one of the trucks had bad brakes which should have been fixed but weren’t because everybody who was supposed to check either assumed somebody else had done it, or that it wouldn’t matter if it was done later because they had something more important to do. . .and that in the OTHER truck the radio was not working properly and again, everybody who was supposed to check bailed. . .and that in both trucks, armed with all this knowledge, each man is deliberately racing along knowing that things which should have been done were not, but more intent on having their own way.
So there you are, looking down, trying frantically to communicate and hearing the static indicating one’s radio is broken, and seeing that even though you managed to ‘contact’ the other one and they’ve frantically started to brake, their brakes are failing and they’re going to collide anyway.
You did everything you possibly could to ensure that these trucks would travel safely, but in each one, the individual decisions of the men, decisions that were personally ‘against’ what you taught and told them to do, resulted in the crash which you can SEE is going to happen though you yourself had nothing to do with the happening yourself.
