you get that a lot on the roads.
As you mentioned people to think to themselves " that car has just smoked me as if i dont exsist, so therefor my manhoods been brought into question"
seems a bit strange TBH why these people do it???!!!

maybe they just need to realise that the Blue, black, green, silver, red, white letterbox shaped scoop behind them means...
dont try it
