Statistically i wouldn't be surprised if the stretch of motorway from the Bont to Sarn has one of the worst fatality rates in the UK.
The number of fatalities seems to get worse every year. I'm sure people's attention being taken away from the road by looking at their phones has a lot to do with it.
Was returning to Swansea the other week, on the M4 approaching Port Talbot , suddenly a lorry swerved, leaving the middle lane, half of it going into the fast lane, if another vehicle had been in the fast lane at the time, who knows what would have happened.
When I caught up and passed him he was looking down at his phone!
