Boy, there is alot of noise on this topic across other race forums as well.
I guess in stock class you are not allowed to pull the fuse. And in some cars, if you pull the fuse, you need to make a trip to your dealership's service department to reset an error code. I don't want that bad dream like Matt's

, so I don't think I would want to do this. Then there is the risk that you will forget to plug it back in when you are done.
The report is from 1999 -- and based on implementation of airbags in F1 cars. But, reading between the lines, I think there has also been some experience of this happening within an scca venue, but I haven't found a specific example yet.
What I would like to see is a dummy-simulation of an airbag hitting a full-face helmeted head. I'm wondering if the impact point towards the bottom of the helmet smashes the chinstrap harder into your jaw; or if the impact causes your face to smash back into the chinbar. ??
