The Google car is only driven in controlled conditions in sunny California. For example the car simply doesn't work when it snows, so they just turn it off for that duration.

The more so as it's adversely selecting hazardous conditions for the human driver.
My own stats, space travel excepted, are about a quarter million miles driven. Three parking scrapes (insufficient clearance / hitting unseen object), twice rear-ended (neither major damage) both times by a trailing car driving too close, too fast.
