The NHTSA found a 40% crash rate reduction from Tesla's autopilot. I'd say thats what its good for.
No doubt collision avoidance is a fantastic feature though.
Addendum: Looks likes the NHTSA has disavowed Tesla’s interpretation of that study. They did not evaluate whether autosteer (autopilot) was engaged.[1]

Wow. This is a story in its own, because that statistics has been touted a million time by the tesla/elon apologists..
Furthermore, no one is forcing anyone to buy Teslas. People should be free to do as they choose. I have no doubt, for example, that a corvette, lambo, m3, or convertible all increase certain risks for their drivers by far more than autopilot - which probably decreases their risks.
