Usually I can come up with some, (occasionally sensible) advice on most issues cyclists face, but I'm not persuaded there is much you can do to prevent slow(ish) shunts from behind in rush hour traffic.
Rearward observation can only do so much and even if you see a vehicle approaching at speed from behind, have you got anywhere to go (try to leave a few metres from the vehicle in front) and can you do it quickly enough to avoid being rear ended? What's more, a lot of vehicles stop, start, accelerate hard, stop - all of the time - can you really be expected to dive for cover every 200metres? On multi-lane junctions, you might find yourself having more problems if you keep squirting left or right.
Whilst there are things you can do to make yourself more visible, how much safer this actually makes you when trying to avoid being rear ended is less certain. Like you, I don't wear Hi-Viz jerseys/jackets, but I do have a v bright rear light cluster. I think this might help in a very small way, but as drivers don't see cars in front of them with 2/3 rear brake lights, efforts to increase conspicuity can only do so much.
I don't think a mirror is going to help much to be honest - it might give you some clues from a distance (when you only want to take your eyes off the road in front v briefly), which you could act on - but once again, I think it will only be of minimal benefit (this is from someone who thinks mirrors are underrated).
If you ride to the extreme left on the approach (and through) junctions you get more close passes and swipes (and lane splitting doubles the risk). If you adopt this strategy, you're just displacing the type of danger you face.
When I filter I try not be the last vehicle in the queue - and whilst it might irk some drivers when I squeeze into the gap in front of them, I at least know they've seen me (I look back) and I give them a thank you wave when I pull away.
