"I apperently undertook an off duty police officer"?

-I was travelling along the A27 west bound towards worthing. In which i was behind an off-duty police officer going at 50 mph in a 70 mph zone, i saw the traffic in the left hand-lane was moving faster that that off the right, therefore with full due care and attention i pulled into the left hand lane and with the flow of the traffic and "undertook" this off duty police officer, i gain a 10m distance between me and the police officer travelling at 60 mph, the van who i was now behind started to signal left to go into a small track that lie off the side of the dual carriageway, therefore with full due car and attention again i signalled right and moved into the right hand lane, further on i moved into the left hand lane to turn left, so i checked my left mirror and also my right, as i was checking my right mirror i notice the off-duty police officer was side by side my car waving his police badge around shouting "I saw you", "I saw you", if this goes to a court i really don't want to lose my licence already as being 17Surely your driving instructor told you that you overtake on the right. You will have to explain your "full due care and attention" to the judge.
Assuming you're in a country like me where you drive on the right and pass on the left, I don't see you having done anything wrong.
How do you know the badge was real, and unless he gave you a summons, don't worry about it.
Unless he had blues and twos going, he can't do squat.
That was just a mall cop trying to play big boy. Blow it off.
if he didnt pull you over and give you a ticket you will not be done.
