Oh, gawd. Now I have to go read it myself. You can track this down
pretty easily at the BMJ site, bmj.com, and download a PDF version.
It's only 5 pages long.

I don't see where they got that "one third of the calls" number above.
As far as I can tell, the study only looks at mobile phone calls.

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.

Feel free to argue the results of the study, but read the study, not
some confused newspaper summary, and please don't do it on NANOG.
