Sometimes when I potter along in the slow lane on an empty M8 I sometimes get near missed with people trying to pull undertakes of the people they are behind - its like I'm invisible. They are racing and not concentrating.
So then I started only pottering along behind something big and hard not to see like a giant truck or bus, and it makes no difference.
Now if they are having trouble spotting something 30 feet tall and 20 wide and usually painted bright orange what chance do the rest of us have ?
