trip:

If that is what it takes to make the GTR acheive these lap times then who really cares how fast it is? Yes its an acheivement but its basically a computer doing the driving. I wonder if we will begin to hear stories of average drivers attempting this technique and running off the road.

 Well, I guess that "running off the road" when "average drivers" attempt to be fast is considered normal for sports cars.

The question is, whether controlling the car via such techniques is desirable and superior in the long run or if it will disappear.

My guess is, that this is just progress and in 5 years from now you'll have the same technology in a Porsche.
