My opinion about DAC is not so much that it is weak. It is that it is not the only source of historical info on a driver. In fact DAC only aggregates the information already out there. This is why in today's world it don't matter if a carrier uses it or not.
i think many carriers actually don;t care about DAC anymore. i think it's the HR recruiters that are new, and told to check out a DAC file. i think that the more experienced hiring office can find the truth with out DAC.
but ya never know until you apply, what and who uses DAC.
