This driver should have his licence taken off him, and a fine issued, as he could've prevented (and may well have prevented) emergency vehicles getting through, when the lane was live, albeit at 40mph. His driving/blocking of the carriage could be construed as dangerous driving (i.e. 'A person is to be regarded as driving dangerously for the purposes of sections 1 and 2 of the Road Traffic Act 1988 if the way he/she drives falls far below what would be expected of a competent and careful driver, and it would be obvious to a competent and careful driver that driving in that way would be dangerous')!!
I was on a family holiday to sheffield to visit the sheffield football ground, as we was driving through Dronfield, This woman in the Blue Evoque took me up the rear driving riduculously close and to top it all off then cut me off into the inside lane and got stuck on the motorway towards Manchester.
What a nob head 👎🏻
