I don't think you should have them, it's already been passed in the UK anyway, but still people do it, I think yesterday I saw someone driving with a Magnum in their hands.
Has smoking been passed yet? Because that's just the same, there's no smoking in taxis, yet the driver's smoking whilst no one's in it. There's still dangers to this ¬¬;
Obviously people need to be aware of public information things. But, handsfree, nah, still doesn't work. You'd still have to be thinking about something other than the road.
I'm not even allowed to drive until I'm 17 anyway... >_<
