Careful, your karma might not take the hit from the autonomous driving crowds at HN. I keep looking at the state of the art systems for autonomous vehicles, and shake my head. I don&#x27;t expect to see them in use in the US in any serious numbers before I die. The obstacles are just too complex&#x2F;difficult. We always denigrate people&#x27;s intelligence, but the human mind is pretty incredible at processing things spatially, even when distracted in a minivan hurtling down an Interstate.
