I heard about this as well. I think Charlie's reply was that "nobody is forcing them to use anything."
I can certainly see incidents being blamed on these devices and the dexterity necessary to operate them though.
But in all seriousness, if drivers on the average American freeway can eat a burger, type a text message, honk at the slower motorist ahead of them, sip on a bevearge, and discipline the youngsters in the back seat, all while operating a motor vehicle, I see no reason why the best racers in the world cannot handle a few more tasks behind the wheel.
