What a bloody idiot - should be locked up - I hope you've passed the information to the police as they will be interested in this? Just in case you haven't I've sent a contact I know at essex a link to this page...
There are only about 3 car lengths when this driver starts moving over to the car coming the other way - this is using the while lines as an indicator - in my view this guy needs a fine and 6 points for dangerous driving...
Fuck this off here right now - it's deformation of character and illegal, i will be reporting this to the police.
