There have been studies that indicate that these sorts of technology (lane keeping/departure warning, auto-brake, blind spot detection) help reduce collisions.

Personally, I don't think that it's right to dismiss these systems entirely if they provide some level of safety benefit, are cheaper and easier than level 5 autonomous vehicles to develop and / or deploy.
