It's not that the research doesn't tell us anything; it tells us the obvious, but it tells it based on data rather than subjectivity. It doesn't tell us how to solve the problem however. There's been a lot of research on this cell phone and driving safety issue in recent years. The research seems to be common sense. I find that I can often predict when a person is speaking on a cell phone just by observing their driving behavior. They have more difficulty than most negotiating turns, getting moving at red lights, etc. The research indicates the obvious; something needs to be done about people driving and using cell phones. Maybe you're right that laws are not the answer. Maybe technology is the answer. The research I've seen does not suggest that the answer is new laws as you suggest.

It's not just driving. I've seen cell phone users having a hard time navigating doors to buildings. This isn't rocket science, however it is useful to have scientists studying this cell phone driver phenomenon; something might be done about it. On the other hand there is something in the Constitution about the right to bear arms! Must be related.

This study (reported in the October 31 issue of the online journal PLoS ONE), also found that an individualâ(TM)s odor signature remained constant even with major changes in diet. The scientists said, "genetically-determined odortypes persist regardless of diet, even though dietary changes do strongly influence odor profiles of individual mice."
