A lot of the one-car accidents that I see out on my favorite driving roads often have skid marks that look like this.
I mean I see marks like this a lot. You can surmise that the guy came in to the curve a little fast, and instead of pushing through it, he lifted off the throttle, and maybe even touched his brakes. The weight transferred to the front of his car and his rear got loose and came right around on him. He then runs off the road on the inside (and of course crosses in to and through the oncoming lane). Now there are a ton of ways to wreck, but if I had to guess, I would say this scenario is the most common "spirited driving" mistake. Most of us have done it at one time or another.
