While OPs statement did make me laugh a bit (I've personally driven almost a million miles myself and I don't think my odds of killing someone were 1 in 4), we do have to realize that MOST miles that make up the 100 million mile stats are done at highway speeds far away from pedestrians. If I had to do 4 million miles in SF, I just might have hit someone by now.
