It would appear that http://en.wikipedia.org/wiki/Drifting_(motorsport) http://en.wikipedia.org/wiki/Drifting_(motorsport) and http://www.driftingstreet.com/oversteer-understeer-slip-angle.html http://www.driftingstreet.com/oversteer-understeer-slip-angl... have relevant information for the analogy that this piece is based on, though I'm not a race car driver. Amusingly as relates the author's point, the latter link seems to indicate that optimal slip angle isn't fixed at 7 degrees but varies based on type of tire - as it says, "For race and high performance tires this optimum slip angle is around 6 to 10 degrees while this number is a little lower for street tires."
