> Furthermore, even 99.99999% reliability is not good enough, and that's already incredibly hard to achieve. Five 9s of reliability still means 5 minutes of unreliable behaviour per year, which is unacceptable in the context of driving. 40,000 traffic accident deaths per year in the US. < 400,000,000 drivers. So more than 1 fatality per year per 10,000 drivers. There's a 99.99% change that you won't kill someone while driving in a given year. That's just fatalities. > In 2017, there were an estimated 2,775,608 police-reported motor vehicle crashes in which at least one passenger vehicle (i.e., a passenger car or a light truck) was towed from the crash scene in the United States, which resulted in an estimated 1,686,240 known passen-ger vehicle occupant injuries.[0] So 0.6% per driver per year. So far today I've seen one driver going the wrong way down a one-way road, and one run a red light. (Plenty entering the intersection on yellow and leaving on red, but at least one where it was blatant). I was on the road for maybe thirty minutes. Do you think the average driver spends less than five minutes per year driving unsafely?
