I am torn. As a MC rider, I am for banning cell phone use while driving, especially texting. I think, texting while driving should be treated exactly like a DUI.
Talking on a cell phone, I believe, can be problematic, especially for young and inexperienced drivers. However, I don't really see it as any more distracting than conversing with a passenger, or listening to a radio program. It's really about how much attention you allow yourself to divert away from operating the vehicle. Hands free does little difference, imo. Ultimately, we would all fare better if everyone stopped talking and focused their full attention on the road. So I suppose, If a ban on cell phone use was passed, I would be ok with it. We don't really need to be on our phones, while driving. The world functioned perfectly fine before cell phones. 99.9% of calls can wait.
