Here’s the research: our attention is limited to one complex action at a time. (Driving or biking is a complex action.) when we are driving the visual and spatial areas of our brain are engaged and focused on the road.  While we are texting, (also a complex action), our brain disengages from focusing on the road and focuses instead on the language areas of the brain and our cell phone text.  Our brain is not built to focus and engage on two complex tasks simultaneously, unfortunately when we text while we drive or bike we lose, our chances of a crash multiply significantly or the poor person in our path loses.

What are your rules for texting while driving?
