Safer than people is not 99%. The accident rate is around 74 per 100 million miles (and fatalities is 1.13).<p>It&#x27;s unclear exactly how to turn that into a percentage, but no matter how you do it it&#x27;s way way more than 99%.<p>Say an accident takes 5 minutes, and people drive 30 miles&#x2F;hour. Then that works out to 99.999% for humans. If you use the numbers for fatalities then it&#x27;s 99.99999%.<p>That&#x27;s not even in the same ballpark as 99%.
