Give me a break
I find it hard to believe that texting is less distracting than eating. One doesn't have to concentrate to eat a hamburger but, while texting, one has to formulate what one wants to text and then concentrate to hit the correct keys to text it. If one is looking at the road while engaging the keys, most of us would have to concentrate that much harder.
We all know statistics lie. Flawed studies lie too! I suspect a major flaw in the study.
