Flip flops at it again?

Why is it some people have to immediately overtake the second they hit the motorway whether it be cars, vans or trucks that they pull in behind from a slip road?

Used to be the domain of the BMW driver but she did the same thing despite it being busy - got to instantly be in lane 2 to gain a few extra seconds as god forbid she should sit behind a lorry. Doesn’t give the truck much chance to notice shes there esp as shes tucked right behind him.

Personally I’d blame her, not because i drive trucks, but because a move like that although technically legal is in my opinion driving without any consideration for others.

This is without even mentioning the near miss caused by a smart motorway!
