The issue is not the risk of adversarial images being used to create mayhem, which was originally a straw man of the 'vehicle automation is infeasible' faction, but is becoming something of a straw man when it is used as the primary target of the 'this is not a problem' side. The issue is firstly the fragility of current image recognition in ways that are not easily bounded, and secondly the fact that humans use aspects of generalized intelligence in recognizing such situations and dealing with them, something that is not yet feasible to the same level in vehicle automation.
