Re: caused by human error and inattention
"Driving is more than yaw computations. Sorry, was that a packet of crisps that can be safely run over or a rock that must be avoided by an aggressive manoeuvre. No time to get a response from Watson in this crappy 4G zone."
A packet of crisps would probably return a different infrared signature than a rock, Plus there's the matter of motion (a packets of crisps will react to the wind differently than a rock due to weight and aerodynamics). And if it's a rock IN a packet of crisps, that's pretty much sabotage at this point.
Put it this way. A LOT of thought has gone into the various scenarios that the average driver faces as well as how we as drivers identify and react to these. The bulk of that knowledge is probably in the prototype cars, already at hand no Internet necessary. Same for the maps.
