Thanks for the replies

My SA is normally very good. I use all mirrors regularly whilst driving. Also my blind spot checking has gone up significantly since passing my bike test

wish it was as good before then.
As for where the other car came from? I had pulled out from L1 to L2 after going past the off slip of the junction. There were no cars behind me in L1 for several hundred yards and I pulled into L2 in a considerable gap of several hundred yards. So to the rear of me was a road that was clear in both L1 and L2. I always try to move to L2 going past an on slip so I am not forced to make any sudden changes in speed or direction by an on slip vehicle.
Total time from pulling into L2 and going back to L1 was about 15 seconds.
I think I had an Obs failure moment compounded by a (as RipPig called it

) Prat. 25 yrs of driving and still the odd error creeps in.
At least it didn't come in, sit down, grab a beer, put its feet up ...
Whatever it is you almost failed to notice, continue looking for that, and it won't catch you off guard again.
Regarding mirror adjustment, I tend to find that most people adjust their side mirrors so that they can see a portion of the side of their car without any head turning, just eye movement.
This blows my mind.
Try adjusting your mirrors so that the edges of the car are not visible until your neck cranes ever so slightly.

As for the phone driver.
I have seen many people drive whilst on the phone and been in many cars where the driver was on the phone. I have not seen such a significant amount of difference in driving ability before and this was on one of the easiest roads to drive. How this driver behaves in a heavier hazard environment would be interesting, if not tragic.

My ambivalence will need to be reassessed.
Personally, the only differences I can detect between a two way radio and a phone, are several protocols involving the use of the two way radio - mostly stick to business, be courteous and professional, get to the point, avoid idle chit chat, either the radio or the steering wheel NOT BOTH ... and the fact that each person takes discrete turns speaking and listening.
Most drivers who demonstrate bad radio protocol and/or etiquette don't last long as taxi drivers. Generally, about 50% of those who want or feel a need to drive a taxi, cannot use a two way radio and drive safely.
I imagine that the non-taxi population shares a significantly lower ratio of people who can safely use a phone whilst driving, because of the lack of protocols; most dangerous being the fact that two people can talk over each other is a virulent breeding ground for massive distractions.
Although I am quite capable of speaking on the cellphone while driving with six or seven passengers without any additional risk to anyone, I have almost never found it necessary. Usually, there are plenty of redlights and stop signs. If there aren't, and the conversation is that important, and the radio is unclear, using the phone with all radio protocols in place, while carefully choosing the time and place to speak, is the minimum consideration required for safe phone usage. (The words 'stand by' are used often.)
In other words, even if I am using the phone while driving, I am driving 1st, and using the phone comes in a distant 2nd only when and where I allow it.
Perhaps the portion of the population - majority - that cannot be trusted to speak on a phone and drive safely at the same time, simply lack, decorum, etiquette, and protocol?
