Matt - my first thought when I saw that was "there's one more reason I'm glad I have an ISAAC", but after giving it some more thought I think that was more a case of someone on the crew dropping the ball. Hell, I crewed for a team at the 12-hour race at Summit last year, and even our little thrown-together crew knew to have one guy dedicated to assisting the driver (in addition to the exiting driver). The one thing I have to wonder, and you Hans guys could probably answer this, is wouldn't the driver have known that the device wasn't properly secured? I would have to think there would be an entirely different feel between just a belt over your shoulder and the Hans under the belt.

As far as other devices, it would seem to me that the ISAAC wouldn't be that bad, as long as all the drivers were set up for it, and you had a helper to hook it up. I hope to get the chance to find out first hand this summer.
