If we raise the stakes to race car drivers, then relevant knowledge on specific tracks, car types, with a performance record would probably be very applicable. When you're trying to find the best of the best in both drivers or developers, the driver should definitely know about how all the components in his machine affect his performance. This also allows him to communicate his intent and any adjustments that he wants made with the rest of the team (mechanics, crew, etc.). The problem comes when employers start looking for talent out of their league, like Greyhound trying to hire NASCAR drivers to drive their busses.
