Research eh?

Now how were the conclusions arrived at?

Did they follow/watch the same drivers using a phone as when they were talking to a passenger about the same sort of subject as in a "distracting" phone conversation? OR when the same drivers were keenly listening to something on the radio? OR when the same drivers were having a heated discussion with a passenger? OR when the same drivers were trying to follow confusing directions. OR when the same drivers were late for a meeting/appointment? & etc, etc.

If they didn't (as I suspect) I think, like a lot of these "researchers" they were looking for confirmation of what they believed and were not "researching" with an open mind. They were looking for what they wanted and sure enough, they found it.
