It's not quite that simple though. "autopilot" is a blah term, but it's also not possible to say whether or not it has saved lives with auto-avoidance and braking. The hard truth is that for things to get better, they need billions of miles of testing, and you can't do that in a lab.
The technology itself is fantastic. Autopilot is the most advanced ADAS system in the world. But the marketing was pure criminal negligence.
