I always wonder if they can slice the data where they compare with decent human driver. I drove for 15 years and never have a single accident. All of my friends never have major accidents (e.g. breaking bones). Sure, we are privileged. We don't drink and drive. We aren't deprived of sleep and overworked and etc. We never have to go out when the road condition is bad. We don't really drive over a speed limit. I'm worried that this "US average" stats is skewed by some bad drivers.
