That would be weird...
People get sick all the time between qualifying and races... But not in F1??? The car and driver qualified... The driver cannot compete for "medical" reasons...
For F1, I would think it would make more sense that you can't switch to a backup car after qualifying begins since there is no practice after Q and I assume the car is toast.
Just an interesting rules question... Wonder if it is either or both... Even if they could find someone qualified/certified to drive there in time.
