This driver doesn't understand how filter lanes work. Highway code says "merge in turn". He will drive so closely to the driver in front to avid allowing others (who have right of way) to merge in front of him and allow him to "skip one car ahead". Beware - one day he will cause an accident by ramming into the back of someone!
You were straddling lanes/encroaching into the bus lane and then you go into the bikers lane with indicating...oh wait you're a BMW wanker so that's normal but then you come out with that garbage!!! "I did see you"
You need to hand in your donor card and ensure DNR is recorded on your medical records because I'm 100% certain no human being would want to be infected by your utter stupidity.
As for your driving licence get a refund as you must have purchased it
