O.G. the police use Cameras to ID Driver that they suspect of Drink Driving, this could have been done in this instance & has been done in the police favour, I was once on the M1 many years back, a tyre blew on the trailer, I was on the hard Shoulder awaiting the Tyre Service, I noticed this car pull on the hard shoulder & the looking at the front of his car, he then set off & pulled in the front of my HGV & said that the Tyre that blew on my trailer had damaged his car ( Happens often to HGV Driver) I said can you prove it, he said no, he jumped back in his car and set off, that are of the Motorway has cameras, & I would have used these in my defence. that cyclist should have demanded this regards the Cameras in that area.
