Pfft. I don't wish harm on any children etc etc.....but can the chuffing 'do goods' just butt out?
They originally suggested a ban on smoking while driving because the driver wasn't in full control of his/her vehicle. Apparently, holding a cigarette means you only have one free hand to steer with. This idea was shelved because someone with a modicum of sense reminded the 'do gooders', that changing gear required one hand to be removed from the wheel also.
Now they move on to the 'concentrated smoke' argument. Shut Up! I don't know which spotty faced book worm dreamed this up for a paper thesis but I guarantee you they never conducted research in a moving vehicle. Any driver who smokes always holds his/her cigarette in the hand nearest the drivers window and that window is partially open. Now, due to the forward movement of said vehicle, suction is produced which immediately draws all smoke outside of the vehicle, even when you exhale.
