You guys are missing something important.

With parallax error taken into account, MARK_UK is only going 137 mph!

I took picture of mine doing 115 or so mph (on a deserted desert road outside of Phoenix-really), and it was a bit unsafe even at that speed to take a pic. I will not do it again. I had hit 130 and it was really hard to keep the car exactly straight with two hands at that speed. The road was two lanes wide in my direction, and I needed both to stay on course. The road is in excellent condition, but in my Crossfire, it was definitely not safe at 130 mph to be driving with one hand.

That is my experience with my Crossfire, and some would argue with that. But it is what I experienced.
