Appalling Driving by Driver From The Courier Guy

I am very appalled at how one driver from The Courier Guy flicked lights at me yesterday, with the intention to say I must get out the way, I'm wasting his time, when there are two lanes which he could have easily switched lanes. I did not appreciate that gesture and ask that this driver be reminded that he is driving a company car and respect all road users. Plate number of the vehicle - FC 97 LV GP
