Ok, but that's just to familiarize himself with the course - any game will do. F1 teams have now developed plug-ins for rFactor which are so true to life that the drivers are able to give feedback to the designers on new components, suspension and set-up before investing millions in actually making the things and flying them out to Spain or wherever to try them out on a race track for real.
Combine this with the GIS data collected from the laser trucks and the simulator knows about every single bump and groove on the track down to the nearest milli-meter. It's really quite amazing - and keeps a fair few Phd boffins employed in interesting jobs for each of the big teams.
