Overtaking of multiple vehicles traveling at the posted 50/national limit culminating in attempting to complete the move on a blind crest. Oncoming vehicle forced FR12GUS to abandon the final overtake of a camper van and slam on the brakes and force his way in behind the camper van and in front of a motorcycle. Later the driver sped through Tetbury and then Doughton and Didmartin well above speed limits yet we all caught up again at the junction with the A46 where he turned off towards Badminton.
White male. 30-40 shaved head perhaps - hard to tell.
