As for the "inattentive-risky driver" and "agitated driver" theories, the researchers took (tried to take) this into acount by using a case- crossover design whereby individual drivers are their own control.
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. :) -- TTFN, patrick
