Why not ban talking to the person riding with you ... because we have already established that conversation is dangerous. To make it easier, why don't we simply pass laws against talking of any kind while in vehicle!
Every time there is a thread dealing with proposed bans, whether it be food or otherwise, there are always those here that will reveal how 'conservative' they are and jump on the nannystate bandwagon. It is really discouraging.
AMEN.
