what they have done here is taken a data set and made algorithms until one of them matched well. If I have a model that predicts traffic patterns or weather patterns in the past, its only useful if it is then applied after the fact and is still comparably accurate to when it was developed.
since its a method they dont normally use maybe they didnt think to use it until 2 weeks past? and also I saw some mention of them passing the info on March 12th, but maybe that was less exact.
And I would assume the car would need to be on for the radio to short circuit?
