Isn't he talking about the "auto accelerate" feature? Even if you have the stick centered, ie no throttle, GVs will slowly accelerate to the max speed for any particular gear if they are moving at all. To maintain a constant speed below max, in any gear, you actually have to pull back on the stick (brakes). This "feature" was added so you could cruise in a GV without having to have the stick pushed full forward. I dislike it intensely because if you do not come to a absolute complete stop in a tank (or shift into N) the thing will start accelerating slowly away to top speed, destroying your ability to fire accurately (ie bouncing up and down).
