Wow, this is news to me.
So it seems the need for human steering input on simple roads (freeways) has been significantly reduced with this feature. Although I generally prefer to manually do things myself, I can see this feature being useful in a long roadtrip situation.
For those who don't know what a Subaru WRX S4 is, in Japan, the WRX is sold only with the CVT automatic with an upscale emphasis on features. There is no manual transmission WRX in Japan, only the WRX STI and BRZ are the two models available with a manual transmission.
