i know its a bit different but my brother and his mate both had mopeds when 16 and they both got caught racing by a copper on his own in a 30 he said they were doing 55mph in a 30 over the average distance now he pulled out of a side road less than the average distance before a busy set of lights and pulled them over they both got producer and court summons through the door but half the details where incorrect on the producers they received so my brother got off his mate got 3 points and a fine
Basically if the copper cant fill out a standard form competently then how can he do you for speeding a good lawyer would have a field day from what you have said so id deffo go to court
