Did you Californians get your head-sets?
All the research seems to say that it's not holding the phone that causes problems but engaging in conversations that is the real distraction.
None-the-less, hand-held cell phone chatting while driving is now illegal in California.
I'm thinking that rather than try and illegalize our drive-time activities we just need to automate our automobiles. Why are we not yet able to simply program our cars to take us to our destination...safely. Seems like something we'd have up and running by now. I blame the Bush administration.
