About time this gets real consideration. Look, you may all feel great talking on the phone while driving with the fancy pants hands-free systems you all have. But every study I have seen indicates it is no safer than holding a phone. You are still a mentally distracted driver. My own employer has had a no cell phone while driving policy from before I started.
On a semi-related note, I don't really peruse the San Jose Mercury website that often. Yes, I know about the gas explosion in San Bruno, but that's about all the local news I know about. That, and some less-than-stellar ex-CEOs are running for office.
