Most of us are pretty lucky when it comes to traffic accidents. Minor fender benders get taken care of by insurance, maybe we pay a traffic tickets, and everyone goes home. Maybe a little inconvenienced but not totally broke and certainly not out by bucketloads of money.
Now consider Tiger Woods. This guy goes out and bashes into a tree and a fire hydrant and the whole thing blows up like Hiroshima. The effect of the accident on golf tickets, the industry that got built around Tiger Woods, and all the accompanying revenue, is suddenly down the toilet. Really, is the economic effect of this traffic accident less than several hundred million dollars? At least.
And so to Tiger Woods goes the distinction of having pulled off the most expensive traffic accident ever.
