I guess I bought the wrong truck !

From my experience, concerning the human eye/mind, and high speed, when not closed course, at some point, it is hard to process your surroundings. Things like a critter crossing the road, or road debris, small bump, etc, cannot be processed in time to avoid, at speeds of 150+ mph. My bike will cruise at 125, about 8,000 rpm, or 3/4s before redline. On a still day, riding one handed, at 140 mph, is no problem. However, just 10 mph faster, is a huge difference, even though just as smooth, it is way more stressful. Even though my bike is capable of near 175, I have never pushed past 160, at which to me, becomes in-sane!

Sorry, to have moved slightly off topic (truck speed).
