What's the closest you've come to having a car accident?

Not counting the time a lady popped her clutch pulling out of her driveway and hit me, since I guess that's not "almost" an accident, probably the time I got caught out by a snowstorm, and on the way home I did a 360 on the freeway before regaining control. Thankfully there was no one else around, so it didn't hurt anything other than my pride.
