Our best of the best image recognition tech cannot see a difference between a zebra, and a sofa in a zebra print. I think &quot;reading hand signals of a policeman&#x2F;workman on the road&quot; is far far far beyond what we can currently do. Or rather - I&#x27;m sure we can make a solution which will work right now, in perfect conditions. I&#x27;m sure it will fail in the dark&#x2F;rain&#x2F;snow or if the worker is making small gestures near his hip rather than moving hands high up in the air. There&#x27;s just so much uncertainty in driving that I think for cars to be absolutely 100% automated, where you can genuinely go to sleep when the car drives, the roads would need to be 100% automated as well, with beacons everywhere. That will probably happen, but it&#x27;s definitely not &quot;3 years away&quot;.
