If we take the analysis done by this third-party at face value, with a crash rate of 10.6 per billion vehicle miles driven and >7B vehicle miles up to 2022 for the Model Y, that means ~74 fatal crashes for the Model Y up to that date.
Sales figures for the Model Y in the US show approximately 425,000 cars sold up to 2022, which means that any given owner has a 0.01735% chance of experiencing a fatal crash in their car.
Put otherwise, you would have to own 58 Model Ys over your lifetime before you reached even a 1 in 100 chance of experiencing a fatal crash.
Which just goes to show how meaningless these statistics actually are.
