This was my first thought as well. Honestly, this "driver must be ready to instantly take over or else maybe everybody dies" category might be the least interesting kind of autonomous vehicle to me for this reason. I really love my ACC for all medium-to-long drives, and wish I had real lane keeping (My car will just comically bounce off the sides of the lane unsafely for 5 seconds and then give up entirely and chide you with a loud chime). I agree completely that that's useful technology. Besides that though, wake me up when they can reliably actually drive while the occupants sleep.
