A1GP v Regular Season

[Kiwi3]

John Martin's unavailability for the Mexico round due to F3 commitments, as mentioned in another thread, got me thinking. To date in almost all occasions drivers have prioritised regular season 'jobs' ahead of A1GP in order to further their regular career, as most of them have the end goal of trying to get to F1.

Alex Yoong is likely done with F1 and building his long term future with A1GP (presume he is a shareholder in the franchise but don't know for sure). The only other occasion I can think of is Adrian Zaugg chosing Zandvoort round over the last round of a disappointing GP2 season (wise choice as winning the Sprint race would have done his reputation much more good than another GP2 round). Can anyone think of any other examples?

I wonder if this will turn around from season 4 once Ferrari are involved. Perhaps with a higher profile in the future and payment to drivers once more sponsors come on board, GP2, Champcar, Euro F3 etc will find themselves without drivers for some round as they will be off doing A1GP...
