Getting out of the way of a police car

[Hackney]

Yesterday I was driving on the M1 Northbound in a 4 lane section. I was in lane 4.
Traffic was very heavy and moving only sporadically.
I heard a siren before I saw it and saw cars a few hundred metres behind moving out of the way. The police car - given the stationary traffic - was making progress by straddling lane 3 and 4.
As it approached though my lane started to move and picked up some speed (only 20-30mph) and the lane to my left cleared completely. It made sense for the police car to come up behind me, past the slow / stopped car in lane three that was helping create the gap then move into lane 3 to make progress.

I moved as far to the right of my lane as I could and put on my right indicator. My thinking was that this would show the police driver that I knew he was approaching and was keeping right.

So, advanced drivers / police did I do the right thing?
- would the police driver see my action and interpret it as intended
- did it make sense to do what I did
- was it a complete waste of time
- did I do anything wrong at all

Thanks in advance for any feedback

What happened ? Did the police car do as you thought, or did it rock up behind you and wait ?

Yes, not held up (by me) at all.
