Electronic Stability Control is a problem for PIT

As a driving and PIT instructor I have noticed a topic that has gone unnoticed by the law enforcement when it comes to PIT.

Many newer vehicles (and all vehicles sold in the United States after 2012) will have some sort of Electronic Stability Control, or ESC. ESC has been around since 1987 and was first introduced to passenger vehicles by Mercedes Benz. There are a number of other names and acronyms for ESC. For instance, GM has Stabilitrak, and Ford has AdvanceTrac. Other manufacturers have their own version of ESC, but they all do the same thing. ESC and traction control differ greatly in that traction control only works while accelerating and provides a temporary transfer of power to either front or rear drive wheels. Electronic Stability Control is an added sensor in a vehicle that monitors the steering input, engine RPMs, and yaw rate of the vehicle and is capable of independently applying braking power to any of the four wheels in order to keep the vehicle moving in the direction the steering wheel is turned.
