"Safer than the average driver" is great if all the below-average drivers start buying Teslas. But if you're converting drivers on the other end of the spectrum then the roads become less safe overall.
Denmark compared FSD data to national incident rates for regular passenger vehicles. So it’s a true average across all passenger vehicles.
Why would you assume that the group of people would be anything other than the average driver?
That's if you ignore the ability to look everywhere all at once which even the best human driver has trouble doing.
It will be interesting to see if the substantial safety margin decreases as more people buy in.
I wish someone who had access to the data would address this.
I do know that there is not much better than average driver! There is much worse than average: people who drive drunk, and a few other classes of people who shouldn't drive at all. However the vast majority are all about equal: in reasonable mental health and limited to the same eye and reaction times. A few people have and follow better training and so are slightly safer - but this is slight. Most people think they are better than average because they excuse their mistakes as a "one time mistake", while confusing "the other guy's" mistakes with the other guy must be a bad driver.
