they do it delibaretly, there are on the CB like
ssshhh "look at the queue behind me hehe" sssshhh....
sssshh..."yep lets see how long we can get the tailback"....shhh
or somthing to that effect
Get a remapped diesel (without a particle filter).
I know I tailgate when I'm about to overtake (not just for the sake of it if that's any better). But some guy in a Scenic got right behind me in slow moving traffic leaving no room for anything, I couldn't help dropping the clutch and giving him some smoke He noticed too as he stopped and left a gap.. I can be a right kevin hunt sometimes!
