Tesla released its safety report in Q2 2020 showing a strong year-on-year improvement in Autopilot accidents, but a small quarter-over-quarter regression.
Since 2018, Tesla has been trying to create a benchmark for its improvement in Autopilot safety by releasing a quarterly report comparing the number of miles per accident on Autopilot versus Autopilot.
Today, Tesla released its report for the last quarter:
In the 2nd quarter, we registered an accident for every 4.53 million miles driven by Autopilot. For drivers without Autopilot but with our active safety features, we have registered an accident for every 2.27 million miles driven. For drivers without Autopilot and without active safety features, we have registered an accident for every 1.56 million miles driven. By comparison, the latest NHTSA data shows that in the United States there is a car crash every 479,000 miles.
In comparison, Tesla crashed on Autopilot every 3.27 million miles in Q2 2019.
That was a significant improvement in just one year.
However, this is a slight increase in accidents in the last quarter when Tesla had an Autopilot accident for every 4.68 million miles.
Note, average mileage gradually climbed to Q2 after a sharp decline at the end of Q1 due to lockdown orders in the middle of the pandemic.
Since Autopilot is currently used on highways where it is easier to accumulate a lot of mileage without accidents and non-Autopilot mileage comes from driving the city, where accidents are more likely, the two databases cannot be compared .
But it is still useful to compare Autopilot mileage per accident year-over-year. The data is far from perfect, but it is the best we have for now.
Tesla will need a lot more data if they want to convince the authorities to allow them to expand their entire self-driving system.
With these improvements, it is important to note that Tesla’s Autopilot and FSD features are currently driver-only features and drivers should always remain careful and ready to control at all times.
