>Waymo’s CEO, John Krafcik, has admitted that a self-driving car that can drive in any condition, on any road, without ever needing a human to take control—usually called a “level five” autonomous vehicle—will basically never exist. At the Wall Street Journal’s D.Live conference, Krafcik said that “autonomy will always have constraints.” It will take decades for self-driving cars to become common on roads. Even then, they will not be able to drive at certain times of the year or in all weather conditions. In short, sensors on autonomous vehicles don’t work well in snow or rain—and that may never change.

This reminds me of the time Bill Gates allegedly said: "640K ought to be enough for anybody", taking about RAM memory.

Why would you say it will never happen? That is just silly. It may be decades out, today sensors may have a long way to go. But it's just silly to say it will NEVER happen.

Never say never!
