Thanks for the video Geoffers, seeing people texting while driving makes me want to drag them out of the car and shove the phone where the sun don't shine.
I've had a driver coming towards me on the wrong side of the road with his phone held up in front of him punching buttons for all he was worth, only rapid avoidance and a long blast on the horn save a head-on. I have also almost been taken out on a island by a HGV driver on his mobile, and regulary follow lane-wandering vehicles on motorway (especially white vans and commercial vehicles).
Every driver should have their eyelids propped open and be forced to watch this video - for the sake of everyone who has to share the roads with these mobile-morons.
