Unusually today I complained to the local force near me about a Police riders actions !
I can usually analyse a 'forgiveable' reason or that something wasn't too serious but this was.
Basically I was on a DC and police rider had been 'in the mirror' for a while as he slowly caught up. Passed me and heading for the one car up ahead before the roundabout.
He had approached the 'small black car (driver only occupant)' with some (but fair) confidence and I think he expect him to use L1, however he didn't. The car has already indicated R to take the 3rd exit off the R/bout and cop also has R indicator on.
Then much to my surprise the cop undertakes the small black car still indicating R and then he pulled back into the L2 ! Action took I'd estimate 4 to 5 seconds - no messing just undertook him !
Although there was no danger to any other road user, of the chap had decided to go left and had not seen the copper he might have side swiped him !
The the cop takes the middle lane at the r/bout and goes R.
Now if any MOP had done this we'd probably be facing points, costs or even all the stress of a Court case. I was disgusted. I tried to figure out if I had at all seen any indication from him that he wished to pull the chap over or any flash but nothing and nothing after either.
He had ridden fine from everything else that I saw. When we entered the town I had seen him glance at a side road and then the did a 'u-turn' round the mini r/bout ahead and went back. No probs all calm and careful ensuring that all road users had recognised his 'u-turn' as it were...
So it seemed really odd that he had done this odd manoeuvre on a neigh empty DC.
Anyway it bothered me so I called and reported it to the local force to pass on to the Traffic - or ANPR team. I stressed that I wanted follow up on this and said who I am etc.

I later had a call from the Sergeant that runs the Unit. He was helpful and concerned. I re-explained what I had seen and he said that they had had a brief chat with him about it (in essence) he claimed that all he could think of was when approaching the r/bout he had taken L! and then the small car had slowed and had then taken the lane to go onto the r/bout.
Twaddle. He definitely undertook, plan as day and then they were both only after this then braking ... I was watching closely !
He made no attempt to go into L3 either but I am a bit less worried about that !
Shameful ... they will call me back tomorrow and I have asked to speak with him directly !

However, I don't think that they will do this. I hope the chap in the car complains. He did a L and went off as we got into the town and never got his number plate.
I didn't want to stop the chap not sure that would have been wise ... but I kinda wish I had ....
Anyone else ever complained ?
The lady I was visiting said that they had seen some terrible driving from Police describing it as overtaking on a bend .... but I know that if you are out and alert you might easily do this with perfect vision but to others it may look different.... but I don't know those details ....
