A photo and a line of text is no evidence of what this chap may or may not have done. Where is your evidence? Are we just supposed to take your word?
Waste of time and effort.
Idiot sped up to prevent us from moving lanes to access the slip road to leave the M1 then proceeded to swerve to the right and and run us out of the lane we were in. He then undertook us to get in front of us. What an absolute idiot and should have his licence revoked. I will be transferring the photos I took to my laptop to try make out the name and telephone number on the side of his wagon or whatever the hell it was. Very very dangerous on such a fast moving busy motorway.
"You think you own the road you (blah blah blah).."
I think you should be asking yourself that question to be honest, Mr YK51OEM. Clearly aggressive beeping (just where did you expect to go?) near a cross..under-cutting..driving one way whilst looking another (notice the car lurch under braking as he almost takes the silver car out)..verbal abuse (Section 59 Public Order).. and also naturally, the Car Tax which you have not apparently renewed.
All this driving because YOU couldn't wait to turn into a side road - stop acting like a spoilt child? A dangerous one at that (hint: that's not a badge of honour here in the adult world).
Good god that's one of the worst things I have ever had the misfortune of seeing .
Shame you removed your hilarious verbal outburst you sound so gruff and manly .
