Unfortunately the scientific data does not agree with your opinion.
The issue isn't whether this is dangerous - science says it is. People want to take this risk. Heavy drinking will kill your liver - yet people still binge drink (and you might be surprised to find out how low # of drinks that defines binge). Don't eat sugar - most have a Mountain Dew in their hand right now. It doesn't matter that a Church van gets whacked by a texting driver and kills many -- not in my backyard.
No matter the number of studies telling of the risks - people will continue to believe that they are above average and that they can operate a cell phone while driving. Years ago I wondered how talking on the phone stacks up against "fiddling with radio, talking to passenger, eating snack" - and turns out talking on the phone is more dangerous for several reasons. One - your participant is not in the car with you. When talking to a passenger - they too can see a sticky situation coming up and will curb the conversation along with the driver. Also people tend to devote more focus on phone conversations than they would say...eating a snack.
IBM once put forward a system that could monitor the road, traffic density, and other attributes and plug that into the cell phone. Diverting calls to voice-mail if you had the brakes on, or heavy traffic etc. The more dangerous the situation and it would lock out external distractions.
Companies like Ford have tested this in their driving simulators. They know. My father has a GM with a navigation system that can't be operated while the car is in motion..... and I'll tell you what.. it is the most frustrating feature ever. I just pull out my phone or Garmin and think....why th' f* pay $1500 for a lousy nav system that you can't use.
