Model S owner manual is at
All in all Autopilot will save you from some pretty stupid behavior and I'd like to have my current car replaced with a Model 3 right now. I'm positive any Tesla you give me (other than the pre 2012 roadster) would be safer than any car I own or have owned.
If you are concerned about safety, there are several autos on the roads that have zero driver deaths year after year.
Tesla isn't on the list.
