Most standard cars already come with emergency automatic breaking.

Is that so? Now if they also could brake...

That's exactly what self driving cars do, silly.

They do it as well on top of some other non-safe features. Less is sometimes more. Breaking when a pedestrian steps before us in sub-human reaction time is great - it doesn’t have to be combined with full self driving, which is simply really far away from now.

It does that as well. Have you ever driven one?
