This is my favorite part:
Evaluated sending/receiving texts, updating Facebook/Twitter and checking calendar by using voice commands while driving.
Seriously? THAT'S what you tested? The only thing on that list I would actually do in the car is send a text, which is extremely easy. "Tell Bob I'm on way."
Why not test map navigation, which is equally simple? "Take me to Panera Bread" or "Take me home"
Why not test music? "Play my Driving playlist"
You see, AAA wants Siri to fail, because it makes a great headline. If Siri turned out to be good, or even middle of the pack, Mac Rumors and everyone else wouldn't share this headline. It turns out if you attack the most successful company in the world, you get a lot of press.
And yeah, as someone else said, their recommendation is probably that you join AAA and use their paper Trip Tik maps, because those aren't at ALL distracting.
