I did that at one of their travelling road show tracks. One segment had a radar gun with a check speed immediately before a hard braking right hand turn. I asked what their fastest speed was for the day and told them I'd top it. I stayed in it so long before hitting the binders that the factory supplied co-driver was white knuckling it and putting his feet through the floor trying to slow us down. His sigh of relief as we made the corner was clear audible and made me laugh.
