...on a per year basis, your odds of dying in a vehicle crash would be somewhere in between 1 and 4,000 and 1 and 8,000. Currently, roughly 40,000 people per year die in car accidents in the United States.
I won't publish the odds of getting a bearing failure based on the numbers of 986/996 sold because some may feel embarrassed.
With that said, "have fun" and drive safely chaps
(and avoid motorcycle road racing if you can)
