I have had 1 car totaled in almost 2 Million Kilometers (1.2 Million miles) behind the wheel and it was because someone ran a red light and T-Boned me. I spend my day on the road in some of the worst traffic conditions, road rage drivers around me, and in some of the worst weather imaginable and have never totaled a vehicle before either my fault or someone else's fault until my Journey which I guess I was due for statistically.
I have been involved in a couple of fender benders as well, again not my fault, someone else running into me. These were minor though and not enough to write off a vehicle or anything.
But considering these 3 accidents in almost 1.2 million miles, I think that's a pretty good average.
