What was scary for me was when driving to my parents house on Christmas day (it's a 2.5 hour trip), for no reason my car almost pulled a complete 360. The roads where dry, they were in good shape with no furrows in them from heavy traffic, I wasn't speeding (it was a 55mph zone), and the tire looked fine afterwards. I was lucky that it was Christmas Day, so the next car was about two miles down the road so I had plenty of time to turn around and get going, instead of getting in a massive accident. It was a four lane road, but separated by some grass that dipped (you know what I'm talking about) and a barbed-wire fence.
Another time I was a moron and took some cues from cars barreling down a highway at 65mph and fish tailed in both directions before I managed to stop. The problem? This was back when there was the huge snowstorm in the eastern half of the U.S. about five years ago. Most people went maybe 30 on the highway, tops, but some people seemed fine booking it pretty fast, even if it was covered completely in snow. Then again, those type of drivers probably explain the miles and miles of wrecked cars on the side of the road. I forget what the average response for AAA was during that period, somewhere around 8-12 hours, maybe?
Just remember that NOT trying to save 5 minutes by flooring it might save your life, your car, and plenty of other headaches (such as killing someone or trashing their car, plus insurance hassles).
