It works just as smooth pulling a trailer. What mode were you in?
In the video, I noticed some loss of torque (speed increasing slowing) after 70, and again after 95. I assume that was the truck and not you letting up on the accelerator. Am wondering if that was computer doing it and if could be reprogrammed.
I got my tires to chirp a little while doing on wet pavement, usually just one wheel at time, so the traction control takes a little less than a second to reduce power to the wheel.
Private test track? Have lines on that track? I'd like to see how blue cruise works at various speeds. Rumor has it that hands-free cuts off at 80, but I could swear I have gone over 80 in hands-free mode.
My test track is I75 (let the lecturing begin) and usually has too much traffic to play around "safely" but I mine seems to be governed at 106.
