Have you got video footage? If people are doing such things they deserve to be filmed..they are putting innocent lives at risk because of their recklessness. Don't let them spoil your day mate :)
Driver seems to thrive on tailgating (and looking to make dangerous overtakes) other road users adhering to the speed limits and when confronted with criticism of the dangerous practice, he reacts aggressively.
Assumedly (and understandably) this driver is incredibly depressed with not being able to afford a decent SUV/4x4 and is using other road users as a form of anger relief.
Would suggest giving this driver a wide birth as he was witnessed aiming his poor man's range rover at another car as he made one of his dangerous overtake maneuvers.
On the A1 southbound near Black Cat Roundabout, Bedfordshire 20/05/16. I moved over to allow traffic to merge from the slip road. One merging driver CP05 BTO decided to race up my nearside and undertake rather than wait behind like everyone else. (Speed limit on this section of road is 60mph) Video:
I was driving down the motorway when idiot cut me up multiple times and was weaving in and out of traffic. She also had 2 kids in the car!
