I didn't do too bad.

My reaction time (on this last test) was 0.35 seconds slower while texting and 5% more gates were missed while texting.
I could probably do better if I tried it again, but I want to give you faithful readers a fighting chance. ;)
Oh, and by the way, I don't think there really is a "Gray Lady." I think they made it up to make me feel like a bad driver.
Good luck!
