Hate to say it, but I'm kinda torn on this one. Yeah, it's bullshit, and we have laws against drinking and driving, etc., but those are still broken, so what's this ultimately gonna do?
OTOH, read the news or look on the web for instances of people killed while texting/talking and driving, or worse, getting someone else killed (or 25 someone else's, in the case of the Metrolink train in CA a few years back.)
And 3000 deaths a year, a significant portion of which would be prevented by such laws? Sorry, but you don't have the right to text and drive, kids.
