So is Tesla behind other manufacturers?? I've seen commercials (Subaru and I believe Volvo) who demonstrate fully automatic braking when the driver is distracted in order to avoid a collision. Granted, there may have been fine print in the commercial stating that it's not guaranteed to avoid a collision, but the ads are pretty compelling in and of themselves. I've tripped the collision warning a few times but never felt so much as a whisper that the car was braking for me.
