Mikey, I've seen them, cursed them, blasted the horn at them, but it's like taking to the wall, I can not understand the brain & sense ( if any ) of these motorists, any person with a bit of Common should know ( SEEN & BE SEEN) many times I've had cars coming up in the Spray of my trailer only to be seen at the last min, It should be a Legal Requirement & a 3 pointer if caught, these measure could be put in place by Motorway / Duel Carriageway Cameras such as the A483 Merthyr.
