car automation has to be good enough that that's a credible suggestion. I completely agree. I suppose what I was trying to get at is that the direction Google seem to be taking this is one where it will end up as an amazing feature on top end luxury cars whereas the technology could be very different if evey car on the road had the same technology and each was constantly aware of every other vehicle in its proximity thus reducing the risk of human drivers interfering with a predetermined path. The latter sounds like it would require additional or even very different technology to implement. That's my two cents, keep in mind I know more about the internal combustion engine than I do about programmed automated technology!
