People vastly underestimate how little data we have on autonomous vehicles. For context, we drive about 3,300,000,000,000 miles a year in the United States.
All autonomous vehicles across the entirety of the last 10 years have only driven about 200,000,000 miles- six orders of magnitude less. That is the equivalent of driving from your house to the corner store and saying youâ(TM)re as good a driver as someone who has crossed the United States 12 times.
If you simply look at the raw probability of having a novel situation or potentially fatal situation over 1,000,000 times more miles, autonomous vehicles have not even scratched the surface. We need to be very, very careful about the idea that we have mastered autonomous vehicles and should roll them out en masse on highways.
