some detail
Check the Telegraph online: http://www.telegraph.co.uk/news/newstopics/politics/lawandorder/4804702/Labour-peer-Lord-Ahmed-jailed-for-motorway-texting.html
Essentially: Court told Audi driver had been drinking and had crashed his car into the central reservation in total darkness. Another car had clipped its wing mirror and a further vehicle had collided with the central reservation after taking avoiding action. The Audi was facing the wrong way, straddling the two outermost lanes, when Ahmed crashed into it. Audi driver thought to have returned to car to collect mobile when Ahmed crashed. Ahmed's text messaging session ended two minutes before the collision.
I think the road laws are wrong headed, as are the comments so far on this story. In general, whatever the road or speed, if you can clearly see there's nothing ahead or to the side of you within your braking distance, then you have brief moments of time which are enough to text/set tomtom/turn around to talk to passengers/flick radio stations and so on. There is no benefit from unstintingly scanning the open road when you can see there's nothing on it, but doing anything else has become a taboo. As always this leads to worse behaviour: when holding a mobile to your ear was deemed unsafe, before it was even illegal, every safety conscious person went out and bought a bluetooth headset. Blocking out half your hearing by wearing a bluetooth headset, imo, does a far better job of interfering with your faculties than holding a phone to your ear. I find them unusable.
I regularly text and speak on the phone while I drive, and have the naus to do it only when it's safe. I am coordinated and can manage this perfectly well. I have 12 years no claims and have acquired a total of 3 points in 14 years of driving - I'm a good driver. Having said that, I have had a couple (i.e. twice in a decade) of low-speed near misses while texting. I would love to try out the driving simulators used to show texting to be dangerous and see how I fare, and wonder if I'd have the option to decide not to text as I go through a blind corner.
Blanket banning specific activities whilst driving is weak, negative law. It's made on the basis that if some of society can't be trusted to do something, then it's banned for us all. People don't respect laws like that. Keep the existing careless and dangerous driving charges, which are more principles-based, allow them to be aggravated (by texting etc.) but don't ban the activities themselves. Arrived at a red light? Why not send a text?
In the Ahmed case, he could equally have been preparing another text, eyes down, when he crashed (ban texts), or, having finished his text session (during which he was also concentrating on the road), relaxed into the drive too much (ban texts?). Or the Audi could have been just over a hill and an accident waiting to happen come what may (ban driving?). If Ahmed hadn't texted at all during his journey, would the outcome be any different?
