James Allen recently had this to say about scrutineering.
"Ever wondered how they test whether the cars are legal? After every race the F1 cars have to be checked over to make sure that they comply with the regulations. But the pre-race legality checks are not carried out by the FIA, they are carried out by the teams themselves. It is up to them to make sure that their car is legal before the action starts. The teams have to ensure that the bodywork fits the dimensional templates supplied in the FIA garage. The cars are weighed, the track width is checked, as are bodywork dimensions like the size of the front and rear wings and the front wing height. Teams have just 10 minutes for each car to check that it is legal. Typically they do this on a Thursday evening. And they had better get it right because once the action starts the FIA technical delegate Jo Bauer can check a car whenever he wants and if it doesn’t comply it can be disqualified.
All the FIA do pre-event is to check that the safety features are in working order, things like the monocoque, the electricity kill switch, the rear light and the fire extinguisher."
I had no idea about that, and I'm not 100% sure it correct. Does anyone have more information about this?
