This is precisely why this sort of thread evolves.
Remember Cardiff and the Andersen/Holta incident?
Holta rode Andersen fairly hard, but tolerable. What happened next? Down came the Andersen red mist and a lap later, he nigh on t-boned Holta and got himself excluded.
In the following interview, all Andersen could say was that Holta did the same to him!
Now I always try not to be anti-anyone. In fact, I think it's a travesty that HA isn't in the GP series (though he will doubtless see the benefit when he returns next year). However, this sort of event only reinforces some of the negativity shown in this thread.
And for the record, I didn't like Nicholls show of unsporting conduct either....
