Using the famous Keith Code analogy of $1.00 = 100% attention, I would bet that talking on a phone or reading takes up about 75 cents of the buck. That leaves 25 cents left for everything on the road. I bet even someone legally drunk is more on the ball than that. I know some states are considering a ban on auto sell use, and it can't come fast enough for me. Ironically, I have had the closest calls while driving in my car. On the bike, my radar screen is much higher and I avoid these people like the plague.
