Jack,

You have let the cat out of the bag. It is a secret weapon, but only for the "new" cars. You see the camera on the tree is synced with the one on the starting line, they in turn read the reaction times and also note if you have spoilers and such hanging down. This information is fed to the computers in the CJ's and Drag Paks. They also pick up on the same readings of the "old" car that is in the race and feed that cars info also. The camera at half track monitors the progress and will feed this into the CJ's and Drag Paks so that it can increase power or decrease it just so they stay ahead of the "older" car that is in the race. The final camera is just for conformation purposes and the drivers of the "new" cars get to down load a pic of them ahead of the "old" car when they check their data.

Mystery solved.
