There was an old game called "Shooting Gallery" that tested how fast you could click things - pop up targets, moving targets, etc.
Oh wait, that would be for programmers or database people like me.
As far as drivers go, I'd go with the above suggestion of an RC car or EduRobot.
More important, however, is the chemistry between the coaches and the driver. If your driver is a stubborn idiot, it doesn't matter how well she pilots. On the flip side, if your pilot is decent, but can make quick judgements and listen to the coaches, you have a winner.
