The drivers are "their own control" by looking at their driving the
one, three, and seven days before. Not exactly a good control if the
drivers did not get an "agitating call" on those days.
But whether it is the call, the phone, the headset, the drivers,
etc., JC's point of "accidents are not increasing in general" sounds
pretty strong to me.
And MOST importantly, none of this is even slightly on topic. :)
