Wouldn't need to be excessiv eyaw. But yaw rate.  As soon as yaw rate 
cause a liit to be reacedd then control uses a mass as a reaction body 
to create and off setting force. Mass free floats on a shaft. Controls 
at both ends to amplify the force. Use magnetics and make very high 
spring rates to put stuff back where it goes. Car would never even feel 
like it was going astray.

As I develop my model of spin mathematics to see how small the yaw angle 
needs to be then I will add some control...
