What's that driver doing?

Just heard a news story that reports at least 80 percent of car crashes are due to distracted drivers trying to eat, change radio stations, pop a CD, apply make-up, etc. etc., The rest can be blamed on cell phones.
I've long suspected this, of course, but I continue to multitask behind the wheel. Most of the people I see on the road do, too. I've even watched people reading during traffic jams.
What will get us to stop?
