Narian is a good prospect for the future, certainly from a commercial point of view. His first season with Jordan was a baptism of fire which managed to deal with. Personally I think it was too soon for him to enter but hopefully he has learnt a lot from his 2005. A test drive at Williams is a great thing for him. He will learn a lot from Alex Wurz.
If he can take on board all his experiences so far, learn from his mistakes and use the testing role to get consistent, then he has every chance to do well.
I wish him and his Indian fans all the best.
It's great to see another country involved in F1. No doubt soon enough there will be a Indian team also.
