I would not have continued the argument in the way that you did. It comes across as goading and threatening. After the first interaction you should have left it and then prepared the reports you wanted to. By continuing the argument for several minutes along a long stretch of road you were in danger of causing a distraction to other road users, as well as an over-reaction from the driver of this vehicle.
So I was ragging my ecoboom around lakeside gp then look to my left to see an m140 being driven by an ice gem, for one minute I thought I was still off my nut but then looked again, it was just an eager Dougy Martin.
