This is a great photo because it calls our attention to this drivers eyes. It is just before the start of the race and he is experiencing a mild to moderate amount of fear. His upper eyelids are wider open than in a normal, resting state and his lower eyelids are mildly tensed. This is a common expression in the pre-race setting - even for experienced drivers with many victories. It is easy to detect someone experiencing an extreme amount of fear - detecting moderate or mild fears is more difficult but much more useful in our everyday lives.
