*slow applause* Wow, that was money well spent. Did we really need a scientific research study to prove this to ourselves? Are we so belligerent and delusional as a society that we need lab confirmation that yapping on a phone makes it tougher to drive in traffic? We all see the signs every day driving to and from our jobs, taking our families around town. I could have told them this for free if they'd have called me, and I'm no scientist. Great job, fellas, you cracked the unsolvable case.
