Re: The Problem Is Proof
How do they know someone isn't looking through their wallet, looking at a map, looking for a dropped a cigarrette, looking for their reading glasses (possibly so they can text but they arent texting!), spilled their drink or an almost limitless quantity of other reasons they'd not be focused on driving.
@rradina- None of that matters really. The police simply want to stop your erratic driving. If you do any of those things and it causes you to drive poorly and the police see, they will pull you over with probably cause. At that point, they're going to talk to you and probably figure out what happened. If you say you spilled a drink while you were actually texting they'll know. And even if they can't figure it out, they cane still write you a ticket.
At any rate, perhaps instead of a texting detector, maybe we just need a more sensors on the road that detect long term bad driving. I'd say in the car (which is easier) except again, i don't believe we'd get opt-in from people.
