It was announced today that the teams missing from Zandvoort will be Canada, Germany, Mexico, Great Britain, and India.
One of the teams not getting any practice ahead of time is Switzerland, surprisingly. The defending champions didn't get a car early? Money issues?
AGR has not mentioned anything about drivers being considered. Certainly, though, sticking Danica Patrick in there, while perhaps not the best option for race results, would be ideal for getting U.S. media coverage and sponsorship -- particularly as no team has ever had a woman race in A1GP yet (only practice).
