Save the ducks
I think Yoong is a good 'race day' driver. He showed a lot of confidence dicing with other drivers without too many silly mistakes. In fact I can only recall maybe 1 or 2 mistakes which didn't harm anyone anyway.
If F1 is such that drivers only arriving at the circuit on Sunday, jump in and drive I think Yoong would do ok (I'm ducking too)
But F1 (and other series) is a lot more about the race on Sunday. He seemed to have struggled with the team right from the beginning of each race weekend, hence inconsistent, sometimes downright poor qualifying( in season 3), requiring hard driving on Sunday.
Because of that, his results in F1 may not be consistent either. May even end up a lot worse than his team mate. He was outclassed by his team mate Bamber in GP2 Asia recently, which did not do him any favours at all. Certainly did not reflect his capability. I actually feel for the guy. But F1 is a tough world and he won't do well if he can't rid of his 'demons'
