Cam car is as much, if not more at fault as the guy undertaking. KU06 NRN was not driving at excessive speed and only undertook as the cam car was hogging lane 2, which is also an offense.
Rule 264
You should always drive in the left-hand lane when the road ahead is clear. If you are overtaking a number of slower-moving vehicles, you should return to the left-hand lane as soon as you are safely past.
So the camera car that sits in the outside lane for mile after mile when the left lane is clear is complaining about the car making steady progress correctly in the inside lane .
It's phenomenal how little understanding people have of driving and correct use of lanes even up to the point where they'll post videos of themselves driving appallingly while complaining about someone driving correctly .
The camera car driver seriously needs to have more lessons .
