Ugh.. this story is all too familiar.
I had exactly the same thing happen to me with an R34 - Red P plater. He kept blowing off in my window to get me to race on the eastern distributor... until i got the shits and gave it a hefty squirt. Left him for dead cos it was stock as... Very very annoying though.
This quote is relevant I think: "Well, animals are not like people, Mrs. Simpson. Some of them act badly because they've had a hard life, or have been mistreated...but, like people, some of them... are just jerks! Stop that, Mr. Simpson!" [Homer butts the warden repeatedly]
