finding factors only seems to come in cluster, but the other two does
haver mechanisms that does make them actually cluster up.
Bus arrival clustering is cause by a well known positive feedback
mechanism since any difference in the interval between busses will cause
more passenres to arrive at the stops before the late bus, making it even
later. Only way to prevent this is to include pauses in each bus's
schedule, but traffic plannners seem to be too stupid to understand this
and tries to do it with tighter schedules instead.
I would expect a feedback mechanism on plane crashes as well.
If there haven't been crashes for a while, inspection becomes lax, crashes
happen and after a delay inspection tightens up again. It's the deay that
causes clustering here.
