Totally agree that action needs to be taken to enforce the existing laws about using mobiles in cars.
In response to a point made earlier, please consider this first hand experience of how the emergency response times are massively improved now:
In around 1997 I was driving up the M1 somewhere between Derby and Sheffield. Suddenly there was a crash in front of me, a driver had hit the central barrier, spun several times and stopped blocking lanes 2 and 3. Other people were out of their cars offering assistance, so I drove on to find a roadside emergency phone (every mile on the motorway) and get help.
I pulled up alongside the phone, got out of my car on the hard shoulder (incredibly dangerous in itself) and made the call.
I could barely hear / be heard with the noise of the other traffic passing within feet of me, and the operator took a couple of minutes to establish exactly where I was before they could get a response rolling despite me quoting the details on the emergency phone
All the while lanes 2 and 3 were still blocked, with potentially people still in the carriageway.
Now it's a call via Bluetooth from the much safer interior of your car immediately and the emergency services know where you are to within a few yards.
I know which scenario I prefer.
