Hmmm - maybe Carl has just come up with an idea for keeping drivers under control without a black flag - have an escalating fee for hitting cones at an event.
Charge .25 for the first cone, then double it for each cone thereafter. Of course, at the 13th cone, it would cost you $1024... That ought to be enough motivation to keep it on the track.
Just kidding - before anybody thinks this is a serious idea, keep in mind that this would actually encourage some people to try too hard to "save" a spin, which is probably more dangerous than driving off under control and eating a cone or three.
