Also one still needs to include the impact bad wheather conditions, where Tesla's AP is not to be used either. Then there's the impact of "incompetent" drivers on the statistic. As a toy example, consider a world where competent drivers cause 1 death per 100mm miles. AP causes 2 deaths per 100mm miles. However, 20% of all human drivers are driving while drunk and/or sleepy and cause 10 deaths per 100mm miles. This gives an average of 2.8 deaths per 100mm miles. Clearly, AP has a better average but you should only use it while you're drunk.
