If I read this right, he is crossing lane 1 to overtake and doesnt see you in front of him?
Sounds like he overestimated his forward speed, and was checking his mirror for anyone coming from behind, and therefore did'nt see that he had overshot the space he thought he was entering behind you.
I often enter the motorway off a slip road at a speed which matches what I estimate to be the speed of lane 1.
I then match my speed once behind the vehicle in front, and spend a few seconds weighing up who is passing, what is going on in front in lanes 1 and 2 (and 3 when appropriate) before contemplating any manouvre.
Occasionally, a car joining behind me is so keen, as to surge past me in lane 2, only to find the vehicle in front or one ahead, is pulling out to pass too. Slip roads often cause a disturbance in the flow of traffic, and it pays to be aware before accelerating away from traffic.
Does this seem familiar to anyone?
In defence of the shades, I wear dichroic shades, which LOOK extremely dark from the outside, and have a "mirror" look, all blue.
From the inside, they are surprisingly light, yellow, and polarised.
Yellow improves contrast in shadows, and polarising reduces glare. They are light enough to wear safely in rain, if the water is causing a lot of reflection off the surface, but from the outside, it looks daft. They also wrap around giving good vision, without the frame blocking any view.
You were in a position to judge, but if anyone sees me with them on in the wet, dont laugh, ask to try them on!!
