en zo ga we er wel achter komen:
Bentley themselves will only admit that a fourth driver has signed to drive an EXP Speed 8 at Sebring and Le Mans, but won't reveal his identity until the fifth and sixth sign contracts.
www.autosport.com is fairly clear with its choice of words though - "Johnny Herbert will join Bentley's driver line-up for the Le Mans 24 Hours in June."
There's no mention of Sebring though.
One could conclude that a two race programme makes decision-making extremely difficult for potential drivers involved.
