To answer the origional question......he has moved because he can see that Williams has better organisational structure and MASSIVE investment for the foreseeable future.

Bar rely on BAT (British American Tobacco) for most of their funding......there is a 'chance' that Tobacco advertising will be banned v soon and this would leave BAR up shit creek as far as investment is concerned.

Also HONDA would then leave BAR. HONDA powers the team. Takuma Sato is a JAPANESE driver who has outpaced Jenson onece or twice and is showing promising form ( for me he is no way as good as Jenson ), HONDA may push for Taku to get equal status or be the No1 and undermine Jensons position. Confidence in your team is Paramount in F1.

To say Williams is poor ths season is possibly true, BUT, I doubt we have seen their real pace........
Both drivers hate each other and dont work together on setting the car up, they are both leaving at the end of the year also so there is a possible lack of commitment.

Jenson will know a lot more about all this than us and will have made a desicion based on what investment there is over the next few years.

Also just to say.....Jenson and Williams didn't want to go public...it was Dave Richards who gave the story to the Times initially, forcing jenson to go public too.
Jenson & Frank Williams had offered to go to the F1 court of Arbitration to sort it all out before anything was made public but BAR wanted to play dirty with the press.

I think he made the right choice......BAR cant possibly keep improving at the rate they have done this year...it's almost unheard of. Williams dont often produce crap cars two or three years in a row either. Like I said we'll never know the full story but there is lots to think about.

Whats all this crap about road cars? As if it has anything to do with F1.....
