It's really hard to judge available traction on any given surface at any given time. I recall the drag strip in Hawaii, which I've run many times. Well ONE time when I hit second hard all hell broke loose, along with tires. The car got near sideways at about 60 mph and I was left wondering, "What the heck was THAT all about. From out of nowhere." Stuff happens, slick spot and I nailed it I guess...
