Is there an unwritten code among white van drivers? Some sort of non-aggression pact? Is that why they're so mardy with the rest of us? I think we should be told.

Saw one white van driver cut up another today causing the latter to skid to a halt. Surprisingly, there was no hooting, no histrionics, no verbals. I can only conclude that there is a brotherhood of white van drivers vowing to only visit their wrath upon any road user who is not driving a white van. Most odd.
