Oh, well. I've said this several times before. So, one more time...
All that'd be necessary is for one of those cars being passed to change lanes unexpectedly (and usually w/o it's driver LOOKING or signaling), or someone having a blowout or mechanical failure, or ONE deer jumping onto the roadway from nowhere, or any one of a dozen other unforseeable happenstances, and someone's day (or several someone's) would be forever screwed royally.
I'm jus' sayin'...
