Conversely though, how many people are killed in the world every single day simply because of human error? When (in the US) a 16 year old gets their license, we don't ask them to provide a formal proof of their driving technique that shows it's impossible for them to ever get in a crash. We say 'you've had the training, you've demonstrated that you can safely drive, be careful out there'.
